Title: UVW Randomizer ignored if using CoronaBitmap
Post by: katzenwaffe on 2022-11-08, 18:10:56

As topic says, if i use CoronaBitmap I cant get UVW Randomizer to work. No matter how i set "Randomize by".

Corona 9 - latest release.

Interesting. Can you also test this with the V10 daily and also the viewport IR?

Rotation works - but not UV offset if CoronaBitmap. I am on latest daily!

Apparently, the Corona Bitmap shader is the devil. It seems to cause so many problems. What exactly is the advantage of using the Corona Bitmap vs. C4D's Bitmap Shader?

OK that's good info. I like the idea of faster rendering, but until the demons are removed, it takes longer using Corona Bitmap with all the errors to troubleshoot.

It’s one known issue of many, but the c-bitmap shader still gets “forced” onto us with cosmos assets. The screenshot is just 1 example…
 
As BigAl said, perform a thorough exorcism or kill it before it kills us.

Thanks for posting a pic of the Chaos Corona team at work.
So, it’s just 1 guy in that "team"? That explains a lot…
