Hi, , now ray tracing is great, but there are still some defects, and it seems that the official does not have the update expectation of these contents:
-
About the lighting problem of ray tracing self illumination, when can the emiss material directly cast light from self illumination? This can greatly reduce the cost of arranging night or lighting;
-
Can you see the reflection of complete DXR effect in real-time DXR? At present, the reflection of DXR effect is only limited to shadow, and some indirect light, without any Ao, GI effect, which will cause some strange light and shadow problems in the dark place;
-
This may or may not be a bug. When I use sky Sphere, or even HDRI backgrop and other objects for lighting, I find that rtgi completely fails under this lighting. As long as sky ball or HDRI backgrop is used, there will be no GI effect inside, that is to say, we can’t get complete rtgi while using sky Sphere or HDRI lighting? According to the test, only rtgi is affected, rtao, shadow, etc. are not affected.
-
About DXR lightingmass, does it seem that the function originally expected to appear in 4.24 is not available?
-
Is there any plan to expand the path tracking renderer into a complete offline renderer?
Thank you for your reply
