I’m newish to C4D (but now 3D) and have a few problems/questions regarding UVWs in C4D (R19). I created a model, and then I made a UVW map for it. I created a material, and all was good. I then subdivided the model, and everything seemed to be working fine. I would do screen renders (render view) and everything seemed ok.
Next I copied the model, because I wanted to try different iterations. I added the subdivisions and everything seemed ok. I then subdivided one level higher (then previous version) on my render and the render came out bad (see attached). The top image shows my initial setting of 3 subd rendered, and then with a higher 4 subds is the lower image.
I went backwards to see what had happened, and it seems somewhere along the way my UVW map got ‘lost’. When I say lost, this is what I mean- When I select my base model, and then go to edge selection, the edges that were my cut edges for my map are no longer visibly selected. When I click on my UVW tag, the map still seems to be there but doesn’t seem to be linked to my model anymore. Basically I lost all connections between my object, the UVW map edges, and the UVW map.
Does anyone know why this is happening, and how to prevent it from happening? (meaning a way that I can duplicate models and have their corresponding UVW maps and tags all stay linked and together)
Is there a way to relink the UVW map with the model? If so, how?
I noticed one thing in the UVW tag that was not checked, and that was ‘lock UVW’. Does this have something to do with it? What does locking UVW do? And if it does link the map to the model, why is this something that needs to be checked, it should exist by default.
Lastly, if needed, this is a cutaway of a jaw model. The material is layered using alphas and the cutaway segment is a procedural displacement, if it makes any difference.
I’ve never worked with programs where the UVW map is ‘lost’ or ‘dropped’, and I’d like to know how I prevent this from happening. Any help would be appreciated.
Thanks for taking the time to read this. Please help!
