Help needed: (RTX shader) Getting hit point properties (pixel color and normal) in Ray Tracing shader plugin

Hi All,

I tried to get the pixel color and normal for geometry hit point via a RTX global shader, but I cannot find an API to do it.

The shader code resides here: https://github.com/tamiroff/CustomShaders.

Thanks
