My PR for a Vulkan Ray Tracing pipeline has been merged into Godot! I’m grateful to everyone in the community who took the time to review. github.com/godotengine/... Want to know more? I'll be talking about that at Vulkanised 2026 in San Diego on Tuesday, Feb 10, 2026! vulkan.org/events/vulka...

Smooth normals implemented over the weekend. 🤓

Godot GDScript ambient occlusion demo accelerated with the Vulkan raytracing pipeline. Fun has just begun!

I figured it out! Godot compresses some geometries when importing Sponza, so some positions are packed into rgba16. I am not sure whether Vulkan acceleration structure building supports that so, sorry, do not compress please.

The plot thickens. What's this?

Improving my #Godot GDScript #Vulkan raytracing demo, I finally managed to fix some validation errors and visualize normals properly. Some geometries are missing though. 🤔

How about Vulkan raytracing pipeline in Godot? 🤖 github.com/godotengine/...

Naive pathtracing needs a high number of samples per pixels to get an acceptable result, and shooting too many rays drastically affects FPS. But then look at the result once it starts importance sampling the light! 💡 #vulkan #raytracing #rust #rustgpu
