3d Body scan

ZBrush Usage Questions
#1

Hello

I could do with some pointers when using Zbrush, as I haven’t used for a very long time. I have been asked to clean up a model (obj) which was created from a 3D body scanner. The model is very dense and has an untidy triangulated mesh. After a bit of research I realised how great ZRemesher is and I have created a clean quad mesh. However it messes up all the uv’s. The Uv’s from the original scan are bizarre and a real mess so I need to remap. I know almost nothing of uving in ZBrush, but I watched a tutorial which shows how to use the attract and protect to paint where you want to uv. If I paint a ‘Y’ shape down the characters back and then try and unwrap zbrush just thinks for a long time and doesnt do anything. Is this because the mesh is too heavy or because I have not drawn enough guides to aid with splitting and laying out?

Any tips would be gratefully recieved. I have attached a load of captures here - cant see them in preview however, might have to load them seperately

Many thanks

Piers

try to generate a lower res mesh for the unwrap. Once the model is unwrapped you can subD the model and project to get all of your details back.

Thanks for being the only person to reply. I will have a look at that.
