Title: Texture Bump / UV Issue?!
Post by: sykane on 2020-11-12, 16:58:38
I assume its not rally an Corona Problem, but maybe im wrong.

If you see my first picture you see I got some issues with my bump on the diagonal part of the model ... it kind of trips ;)
I just want an continuous honeycoomb al through.
Attached also images of the texture and Bump Settings... I assume its something easy to resolve, hope somebody is so kind to share his/hers wisdom!
Is Thera an issue with UV settings or so?


thx in advanced!

It's triplanar's blending - set it to 0.0 and there won't be that weird doubling issue, but... you will get hard seam. Best solution would be manually unwrap your object and get rid of triplanar.

You wouldn't use triplanar in this case, as the UV mapping needs to follow the surface (and triplanar projects it from 3 directions, and blends between those on surfaces that are not directly facing one of those three directions).

Ah cool... the 0.0 setting worked, but not perfectly... already checking YouTube for UV Tutorials, hope to figure it out... thx!

Looks like it's still a planar or cubic UV, while you'd need the UV to follow the surface. You'd have to look over in C4D tutorials etc. for how to handle UV unwrapping in C4D (as that's not a Corona-specific feature).
