intersection_filter/occlusion_filter?

[zhuyuxiang1994]

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

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)

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
