Title: Working with Multiple UVW Channels
Post by: MattiaPenazziArchitect on 2024-10-17, 01:52:53
Hi everyone!
Technical question.
I'll start by saying that I’ve always struggled with UVWs and I just can’t seem to get the hang of them... However, I have an object imported from 3ds Max where three UV maps are applied simultaneously. In Max, I saw that the material uses these UV channels to indicate how different textures should be placed (for example, UV channel 1 for the diffuse, UV channel 2 for the normal map, etc...).
Now, in good old Cinema 4D, I have these UV channels, but I have no idea how to use them. I know there’s an option to choose the UVW channel within the Corona Bitmap, but nothing changes; it’s like it doesn’t work.
Does anyone have any advice?

Thanks!!

Can't say it for sure, but I believe it depends on the order of your tags. It is something like: All material tags use the UVW tag on their left. (or on their right?) Can't test it out for myself right now.

Don't bother, the parameter doesn't work, I've been asking for this to be fixed for ages. Anisotropy Orientation UVW channel doesn't work either by the way.

Ah, okay! Wow, is there a way to achieve the same effect without using Corona Bitmap? Some kind of workaround?

Not to my knowledge, hope it will be fixed some day !
