Extracting the UV-map:
There's a video
here, but it's 5 minutes and I didn't have the patience to look through it, so here's a written one. The steps are probably shown in the video if you need picture references.
- Extract mesh + texture
- Open mesh in Blender
- Click the (+) button for the "s4studio_mesh_1" (or the mesh you want to extract from - could have a different name)
- Click the "s4studio_mesh_1" name directly below (mesh will highlight in orange***)
***if it doesn't, there are some boxes at the bottom, one is called "limit selection to visible" and one "face select". Click both. The mesh should look see-through with lots of lines. Hold Ctrl and mark the entire mesh, should highlight in orange.
- In the bottom left corner there's a triangle shape. Click-drag this. It makes a new window pop up.
- The picture next to this new window has a dropup list, choose "UV/Image Editor". You should now see the UVs of your mesh in that window (lots of lines).
- Highlight all the lines (Ctrl + leftclick-hold-mark). Should now show in orange.
- Click "image" at the bottom. Find and select the image you extracted in S4S.
- Click "UVs" at the bottom. Then click "Export UVs". Save with a new name. (You can also change size and all that, but by importing the texture you get the size of the original texture).
I worked on it several times- I guess since I last posted about definitely trying. Couldn't get it to work- maybe tomorrow
Thanks so much for the instructions and assistance.
