Ray Tracing in Custom Node?

Hello, folks.

I want to use ray tracing for a specific purpose on a specific material. Unfortunately, UE’s ray tracing capability seems to be limited to the check boxes in the Post Process Volume.
Is there any chance that I can use the custom node in the shader graph and HLSL to do this?
It seems quite impossible to me because things like DX12 Acceleration Structures cannot be accessed by the custom node. Or is it? And how would I access them?

Does anyone have experience with this or at least an idea?


Hi, i’m currently stumbling over the same Problem.
I would also like to make use of part of the DXR Acceleration Structure for one specific material with Custom nodes. I can’t find any documentation on the Acceleration Structure implementation.
