Title: Preparing geometry it takes a long time
Post by: archimen on 2019-02-20, 01:19:04

Hello,
A scene that is only 35 mb preparing geometry about 1.10 min. This makes it impossible to work IR,
Can anyone check it?
Also, when I use Portal Light with the VFB renderer, the materials have a strange structure.
Can someone check it?

edit:
I solved the problem with prepraring geometry.
The problem was .... IES light. I've added the standard from the corona installation folder and everything works as it should. Previously I had it from the library of cinema 4d. The light portal still has a problem. Any tips. ??

Hi, when sharing a scene to us can you please make sure you 'save project with assets'? Otherwise, we just get a scene with black textures ;)

I noticed that the texture problem does not occur during IR, but when the final renderer is in VFB, there is still a problem with the light portal.
The same image without a light portal renders about 59 minutes, and with it 15 minutes !!!
What's up?
