-I have convert selection to UVs and select shell on a hotkey but i'm trying to find some more tricks to speed up my workflow and was hoping some people here would be willing to contribute some of their own personal tricks, scripts, etc..

Id like to ask if there's any way to copy a selection of UVs to another UV set. Ive tried "Copy UVs" but that doesn't seem to work.

Convert selection to UVs is great but for some reason in Maya when you convert to a certain selection in maya you are not truly in that selection because you cannot add or remove from that selection until you use the hotbox.

Couple things i'd love to see in the UV editor:
-Contiguous selection within the editor,selecting loops and rings (although it works ok to do in ppersp view)
-Lattices and other deformers on UV meshes
-Copy selected UVs between UVsets (unless someone knows how this works)

any UV tricks anyone might have would be great...

Hey dude :)

-Contiguous selection within the editor,selecting loops and rings (although it works ok to do in persp view)

I use persp view for this as well.

-Lattices and other deformers on UV meshes

Lattices are available in the UV window as of version 7.0

-Copy selected UVs between UVsets (unless someone knows how this works)

What I think you are lokonig for is called transfer in the poly menuset. It allows you to copy a UV set from one model to the next.

My favorite UV "trick" is to duplicate a copy of the model, and smooth out difficult ares to map (The inside of the nose, ear, creases aruond the eyes, nostrils...). Smooth these aeras out using the artisan tool, average vertices etc. Then do my UV mapping on that smoothed "melted looking" model. Then do polygons-->Transfer UVs back to your original object. This will get you started a lot faster than working with the original.

Best of luck!

Hey man yeah we're using Maya 6 at our studio.

Thats a good trick about averaging the vertices on the actual model and smoothing it for UVs. A nice way to get your initial projections.

Another thing I do is probably just common sense but I like to call it "Pre-UVing" Cause i thought it needed a name. Anyways. Its when you know you're going to model many of the same type object and you find a common point in the creation of the models UV it at that point and then do any modifications to the model, add vertices, deform the shape.. etc. Basically building a base mesh or primitive for the rest of the batch.

But what I meant about the "Copy UVs between UVsets" Is actually for the same model. WHen you're working with one model and multiple UVs and one area of that model can share the same UVs. Select those faces and copy the UV coords from those faces to the other UVset. I haven't found a way to get this to work...

yes it works don't remember for sure, because I always struggle with it for a few second, but i think you have to select the face of the object or the Uv themself butthat sound too logical right.. ;)

thematt, thanks man that worked great! I just select the UVs and copy UVs to existing UVset
