The only time I find it necessary to use the UV tools is when the model was exported from Lightwave itself, which creates an extra set of faces Just inside one of the cube sides when you create a cube, hidden but 3dcoat tries to texture them, this caused me headaches, so I stopped using L.W., similar things happen when I export vert/face modeled objects from fragmotion 3d, forget to turn off 2 sided faces, also if I don't weld all the verts, weld all doesn't fix it, even using weld verts from 3dCoat import OBJ. I Only Manually UV Edit, when painting and a face messes up, letting me know that the UV of the face, is NOT as it should be. I go into UV, and select: -add clusters(lft menu), -islands(top opt.), then click the face, -upd. Islands, -unwrap, -Apply UV Set -yes I understand, viola the face is fixed, and now it paints works perfectly. I have ran across a few models, I was unable to fix no matter how much I tweaked. I can never select the verts / faces that I need to del. / upd., even if I follow the hints closely.. Ex. is the 2 faces from the L.W. cube model, I wanted to del. the extra 2 faces, even though I managed to select & hide the outer faces, I still could not select the inner 2 bad faces, even with outer faces hid, while I tried to click on the inner ones it selected the hid outer ones.. So I tried editing the UV's, hitting del. on the selected bad face, nogo, so then I looked at all options on left menu, none seemed as a delete option, I selected a few which were wrong, like clear, I still couldn't manage to del. the faces from the model, so I just redo my model, using other tech., other programs, welding all verts, no extra faces, I also select: remove all orphans, save a *.ugh frag3d backup file for future adjustments, export the object, hold my breath, cross my fingers, import the new model, usually it works.
Sometimes I have to do some wierd stuff, export the obj file from 3d coat, use U3D to adjust the UV's, deleting extra faces etc.. save it, re-import into 3DC, finally paint it. The bucket fill tool, Modulation fill's, Allow you to create custom fills, and even use them in other tools like paint. It is a really good tool.
I hope this information helps users both new / pro's, as well as gives Andrew some insight into how users are using 3DCoat and some of the issues causing tough problems.. Also, I'm glad to see Andrew fixed the Paint.Net stuff, as I had been working with the psd plugin author of paint.net to fix the issues, whenever you would select the rle-compression option in the psd file save dialog of paint.net, is when I noticed all the crashes happening between paint.net and 3d coat, eventually paint.net was unable to read the psd files, and 3d coat was telling me their was a problem with the format.. That was before I'm going to heavily test the fixes Andrew stated he did for Paint.Net support today, as I make use of Edit Projections in External Editor Quite often, mostly because I can't figure out how to draw a straight line in 3dCoat.. Ok, I'm off to do some more testing, I hope this helps MadDox understand about the UV mapping, and Andrew alike..
