Title: Corona texture baking uv issue
Post by: mrtyner on 2018-03-21, 17:17:31

Hi all, I'm having a lot of problems with certain meshes not rendering to texture properly. The attached file renders perfect in Standard / VRay. Corona seems to be having some issues, however. I'm baking to ch.2 - not sure if that matters but my next test is baking to ch.1.

If anyone can help, it'd be much appreciated as this is time sensitive...naturally...

Thanks!

The issue is those dark polygons?
Could you post a good vs bad render?
Could you share a scene where it happens?

Hi! Thank you /u/maru for your response.

This is looking more and more to be a channel problem slash user-didn't-know-enough-about-baking-textures (and probably still doesn't) problem. I was doing some funky stuff with UnwrapUVW channels and it was messing up the render.

What I wound up doing was writing a script that would attach models by <criteria> > add an unwrap ch3, > pack/break the uvs > render > save elements > copy ch.3 to ch.1 <--(time suck!) -- NO ERRORS!

That might be the long way around, I'm not sure. I'm just happy to have a path forward!

And a couple of the test renders!
