Hi,Does RadeonRays support user filter function to do alpha-test? or there is any way can achieve alpha-test?

devshgraphicsprogramming commented 6 years ago

That would need either:

You to continue casting rays after first-hit and alpha test fail along the same ray
Radeon Rays to accept user-defined "Intersection" and "any-hit" subroutines which can terminate the ray or modify the ray payload (like Nvidia RTX)

devshgraphicsprogramming commented 6 years ago

Well actually in DXR/RTX "Intersection" Shader cannot modify or read the ray payload

Thanks for your reply. Well I know,Compare to DXR/RTX,RadeonRays is a toy for children. I am so disappointed with AMD

devshgraphicsprogramming commented 5 years ago

I'm not an AMD developer
