[H1] Testimonials
Here’s a few examples of what people have been saying about OGRE:

“We are currently using Ogre3D in our naval simulator. After trying other 3d graphics engines, Ogre3D was by far the best for a good combination of qualities: clean and understandable code, excellent documentation, and a great community.
Those three characteristics make me choose it and so far, after almost a year and a half, I have never regretted that decision. Ogre3D has helped us a lot by speeding up the prototyping phase, testing new techniques for the physics algorithms really quickly, and, as part of my Argo Engine, serving really well as the presentation module.”
Alvaro Pereyra Rabanal
Independent Consultant , Peruvian Navy

“Ogre’s complete feature set, along with the very well designed and documented API made it the perfect choice for our upcoming titles. The engine enables us to use cutting edge technology without having to lay out hundreds of thousands of dollars for licensing fees which is invaluable for small teams on a tight budget. As questions on the forums are never left unanswered, the support also leaves little to be desired. And if there is still something you need which you cannot do yourself, there’s always Torus Knot Software around to help you.”
Thorsten Lange

“Ogre is a shining beacon of open-source development. Boasting an efficient and versatile rendering engine, a clean, elegant API and a supportive community that leaves no question unanswered, Ogre offers a product which outperforms leading commercial rendering engines. Ogre has proven itself as an enabler for rapid 3D application development.”
Development Team
3DNA

When we were designing Blink 3D we knew that in order to take Web 3D to the next level we needed a high performance cutting edge graphics engine. In our search we examined and instantly discarded a number of respected graphics engines both commercial and open source.
When we looked at Ogre the bar was instantly raised, it easily fulfilled all our criteria and more. The clean, extensible, object oriented architecture was well suited to our needs. Some open source projects often consist of cryptic, un-maintainable, spaghetti code. The thing I like most about Ogre, is that I do not feel compelled to have a shower every time I touch the code.
Clive Jackson
CEO, Pelican Crossing, Inc

We use OGRE as a rendering engine to develop the webshop of the future. Imagine a real store where you can go through the courses and view the products. We are working on a prototype of a new online shop software, realising a totally new shopping experience. Thanks a lot for the library.
Philipp v. d. Born
Compredia GmbH

To the seasoned developer OGRE looks different. It is like the carbon steel knife my friend uses to cut sushi in his restaurant. Deceivingly simple, yet a very potent tool in the hands of a craftsman. A single blade, a single purpose. The Zen of 3D engines, if there ever was one.
Kai-Peter Backman

During the development of Supremacy: Four Paths to power I had the pleasure of using Ogre to create the particle effects and GUI functionality our game needed. Due to its object-oriented design, it was easy to pick up Ogre and start generating functional content quickly. For example, if you can learn how to use one type of particle generator in Ogre, you already know 90% of what you need to use all of the other types.
In addition, creating the scripts for interface components is a breeze since Ogre’s approach is clean and straight-forward. While you can (and we did) manipulate GUI components through code for advanced effects, it is easy to get GUIs up and running quickly. Ogre’s well-documented design makes it great both for prototyping and for customization of a finished product.
Vance Vagell
Supremacy: Four Paths To Power

Ogre has provided us with a solid, reliable base to build a powerful, ground-breaking, commercial platform. It provides a sufficient level of abstraction from the underlying rendersystems to provide a very simple interface balanced with the power to reach down to the hardware should it be necessary.
As an accolade to it’s stability, it has performed outstandingly in an embedded environment. The transparent portability has allowed the development under a Microsoft environment and subsequent deployment on Linux with painless ease. With constant ongoing development in a growing, and evermore supportive, community, we have visions of using this engine for many years to come.

[H2] Ogre 14.5 released

by Pavel Rojtberg | Jan 10, 2026 | News
Ogre 14.5.0 was just released. This release contains some significant bug-fixes and feature additions, which we will discuss in more detail below. We recommend all users of the 14.x branch to update.
For a full overview of the changes, see the changelog.

Correct Colors: Automated Linear Workflow

Smarter MSAA Memory Use & Mobile Gains on OpenGL
[H2] Correct Colors: Automated Linear Workflow
Left: Gamma Colours – Right: Linear Colours
The “Linear Workflow” as described in GPU Gems 3 is now fully supported, finally resolving the “washed-out” look previously associated with “sRGB Gamma Conversion” Option. The RTShader System’s new setTargetLinearColours feature automatically generates shaders that convert color values to linear space before lighting calculations, ensuring physically plausible results for both PBR and classic Phong shading. Additionally, the new setUseLinearColours option in GpuProgramParams enables efficient CPU-side gamma correction for custom shaders. These updates allow you to adopt a mathematically correct lighting pipeline using your existing gamma-space materials without manual modification.
[H2] Unified Relaxed Shader Precision
Ogre is unifying shader behavior across platforms by defaulting to relaxed precision (16-bit) in fragment shaders. This update aligns desktop rendering with mobile standards (GLSL ES), unlocking performance gains on Vulkan and D3D11. By defaulting to mediump we are ensuring consistent behavior and making it easier to catch precision-related bugs on desktop hardware.This feature is enabled in the RTSS and available now on Vulkan and GLES, with D3D11 support guarded via the USE_OGRE_FROM_FUTURE macro. This paves the way for Ogre 15, where relaxed precision will become the unconditional standard.
[H2] Smarter MSAA Memory Use & Mobile Gains on OpenGL
RenderTexture MSAA across our GL RenderSystems got a significant enhancement, focusing on memory efficiency and cross-platform performance. By adopting a robust pooling strategy similar to our existing depth buffer system, we’ve optimized MSAA RenderBuffer sharing to minimize GPU memory waste while eliminating artifacts in complex “ping-pong” rendering scenarios. This release also brings MSAA support to Multi Render Targets (MRTs) in GL3Plus and GLES3 – a major win for deferred shading G-buffer passes – alongside the introduction of TEX_TYPE_2D_MULTISAMPLE to allow for custom, shader-based resolving. Finally, mobile and tile-based GPU performance sees a boost through the implementation of glInvalidateFramebuffer, which eliminates costly memory write-backs to ensure your applications run more efficiently than ever.

[H2] Ogre 14.4 released

by Pavel Rojtberg | Jul 26, 2025 | News
Ogre 14.4.0 was just released. This release contains some significant bug-fixes and feature additions, which we will discuss in more detail below. We recommend all users of the 14.x branch to update.
For a full overview of the changes, see the changelog.
[H2] Table of Contents
Full Layered RenderTarget Support
Initial Icon Font Support
New Bone Debug Drawing
Improved Bullet Component
Ecosystem: OgreWater now runs everywhere
[H2] Full Layered RenderTarget Support
This release introduces major upgrades to our layered rendering capabilities. You can now efficiently render to multi-layer targets like cubemaps and texture arrays. The key feature, per-rendertarget instancing (VPRT support), enables rendering to all layers of a texture in a single pass. This dramatically reduces draw calls – by up to 6x for cubemapping and 3x for techniques like PSSM3 – addressing a core performance bottleneck in complex scenes.
These improvements are built on several foundational updates:
Add support for 2darray and cube shadow samplers in OgreMain
Targetting layered textures with the ShadowRenderer to consolidate multiple textures for a light source.
Declare texture arrays directly within Compositor scripts.
Using layered textures in the RTSS ShadowMapping SRS for more efficient binding.
This new API expands on the instanced stereo concept from Ogre-Next, scaling it from two targets to a flexible N-target system.
Achieving this required extensive cross-component development in RTSS, RenderSystems, and core architecture. This was made possible through the sustained support of the Patreon community – i.e. this work was sponsored by you.
[H2] Initial Icon Font Support
Ogre now supports using Icon fonts by merging them into your main font. For this the “merge_font” property was added to the font scripts, which specifies the font to merge into the current one.
Text-only UI
UI with font icons
Check out the screenshots above to see the difference it makes in the meshviewer!
[H2] New Bone Debug Drawing
The latest update introduces a new debug drawing, inspired by tools like Blender.
Old transform drawing
New hierarchical drawing
Instead of just seeing individual bone matrices, you’ll now see the connections between bones, making the bone hierarchy instantly clear. This also means the axis visualization is always perfectly sized – it automatically scales to the next child bone, so you’ll never struggle with tiny axes again!
[H2] Improved Bullet Component
Thanks to a valuable contribution from user slapin, the Bullet Component now supports Terrain (heightfield colliders) and features a simplified API for kinematic (user-controlled) objects.
[H2] Ecosystem: OgreWater now runs everywhere
Thanks to some crucial groundwork laid by slapin (again), I’ve successfully ported OgreWater to the OgreUnifiedShader macros.
This means, that OgreWater now runs on every RenderSystem available in Ogre, including the modern Vulkan API – instead of being restricted to D3D9 and D3D11.

[H2] Ogre 14.3 released

by Pavel Rojtberg | Sep 22, 2024 | News
Ogre 14.3.0 was just released. This release contains some significant bug-fixes and feature additions, which we will discuss in more detail below. We recommend all users of the 14.x branch to update.
For a full overview of the changes, see the changelog.

[H2] 3D Gaussian Splatting and VET_HALF support
Ogre 14.3 now comes with an example that shows how to render 3D gaussian splats alongside with normal mesh data.
A point cloud vs the rendering as 3D gaussian splats
To efficiently store the splats they were converted from the original .ply files to native ogre .mesh files which reduced the storage by 10x. See my blog post for the details of the procedure.
To achieve this reduction the new VET_HALFx types were introduced in Ogre, which allow storing vertex attributes using 16bit floating points.
As the most useful VET_HALF3 type is neither supported by D3D9 nor by D3D11, Ogre will transparently pad it to VET_HALF4 on loading. This approach maintains reduced file sizes on these render systems with a slight increase in loading time. It’s worth mentioning that all other rendering systems, such as Metal and Vulkan, do support VET_HALF3.
[H2] Mesh Shader Support
Initial mesh shader support has been introduced in Ogre. They are supported on GL3Plus via GL_NV_mesh_shader and on Vulkan via VK_EXT_mesh_shader. Although the loading and processing of these shaders is now supported in the OgreMain component, the rest of the pipeline still needs to be developed in upcoming releases. Specifically, the generation of the meshlet structure, which is essential for the effectiveness of mesh shaders, is not yet available. Storing this structure will likely require an update to the .mesh format, which must be handled carefully to ensure backward compatibility.
[H2] Wayland Support on Linux
Thanks to the contributions of “Joakim Haugen”, “benjaminvdh” and the work of yours truly, all OpenGL and the Vulkan RenderSystems can now be compiled on Linux without any X11 dependencies and will use the Wayland display server instead. This is particularly beneficial for running Ogre on embedded devices or through WSL.
If you use OgreBites, this feature is automatically available by setting the environment variable SDL_VIDEODRIVER=wayland to instruct SDL to use Wayland. There is also initial support for OgreBitesQt, but Wayland interoperability with Qt is still under development and not fully functional with Ogre yet.
[H2] HighPy module for Python
The new HighPy module enables Ogre to function as a lightweight Python renderer. As the name implies, this module offers a high-level API, allowing users to start using Ogre without the need to read the documentation.
If you want to render a mesh it is just:
import Ogre.HighPy as ohi
ohi.window_create("ohi_world", (800, 600))
ohi.mesh_show("ohi_world", "DamagedHelmet.glb", position=(0, 0, -3))
while ohi.window_draw("ohi_world") != 27: pass
This will load the gltf2 file using the Assimp Plugin and display it using our Filament-based PBR rendering pipeline.
GLB file loaded with HighPy
ImGui Overlay with HighPy
want to add a GUI to that? Add
import Ogre.ImGui as ImGui
ohi.window_use_imgui("ohi_world", ImGui.ShowDemoWindow)
want to display an background image?
ohi.imshow("ohi_world", "image.png")
This will use the secure image-rs rust plugin to load most image formats.
Then there is Physics with the Bullet component and headless EGL rendering on Linux..
Another improvement to the Python bindings is that Ogre now works better with Python threading. Previously we would just hog the GIL preventing any other (python) thread to run. Now you can allow python threads while waiting for vsync by calling Ogre.Root.getSingleton().allowPyThread()
Finally, the Python modules are now part of the official Docs.

[H2] Ogre ecosystem roundup #9

support manually specified mesh LOD levels
initial support for OgreNext .json materials

[H2] Ogre 14 User Survey Results

by Pavel Rojtberg | Mar 5, 2024 | News
Between January 20th and February 25th, we gathered 54 responses. Among these, only one person mentioned using the pip package, whereas the ogre-python package was downloaded 3000 times. Although the findings are informative, they may not accurately reflect the broader picture due to these disparities in response patterns.
A notable observation is the duration that users have been working with ogre. The most popular choice, representing over 27% of the total, has been using it for more than 11 years. However, the group with less than 2 years of experience accounts for 42% of the overall user base. This suggests that Ogre continues to attract new users effectively.
Regarding RenderSystems, we observe a considerable decrease in usage for legacy systems (D3D9, GL). This trend allows us to explore new techniques for enhancing performance, which are not compatible with these older APIs. However, considering the absence of RTSS support for Metal, I question whether users understood that the survey was only for Ogre and not Ogre-Next.
As always statistics are lies though, so better take a look at the actual numbers yourself.
