Hi there,

could you provide some more details on the exceptions you are seeing or alternatively could you provide a minimal repro project?

Regarding the tutorial you linked to, I’m not sure if you have seen [this thread](https://forums.unrealengine.com/t/community-tutorial-how-to-create-a-custom-ray-tracing-shader-as-a-plugin/1139396) on the Unreal dev forum, which contains some interesting discussions and might be useful to make the tutorial work.

You may be interested in looking at [inline ray tracing](https://microsoft.github.io/DirectX-Specs/d3d/Raytracing.html#inline-raytracing) , which was made available in DXR 1.1. This should simplify shader development as it doesn’t use separate shaders.

Thanks,

Sam
