press TAB, select front part of model (B key) and press TAB again
unwrap with U key
press TAB, invert the selection with ‘Select Swap’ button , press TAB
U key again
After these steps, there are faces in the middle, which were never selected and
don’t have UV assigned.
Is there any way to select these faces automaticaly? The model is quite complex
and I don’t want to do it manually.
I think it could be possible to do in python. Did anybody try something like that?
If you go into the python-plugins board, Theeth has made a UV unwrap script for you to run which will give you the shape of the textureing you need to apply. However I don’t think it rewraps and automatically matches your face cooridinates to textures. The flaw in the steps you took, however, seems to be that you went into edit mode by pressing tab…I don’t believe this is necessary at all. You can just select the faces as you described without doing that step.
I don’t need a special script for unwrapping, results from U key are fine.
Without pressing TAB I can’t see unselected faces, because whole mesh is white.
Mooreover, ‘Select Swap’ button does not work at all.
I have another question: Can I lock (or save) UV coordinates for some faces to prevent
accidental changing them?
Maybe it is another tast for python. I am going to look at it at the weekend
I can’t answer all of your questions, but read through this tutorial carefully for some great information about UV mapping that MIGHT answer some of them:
Just chimming in to correct a little misconception, my script doesn’t unwrap polygons (well, AFAIK ), it exports the layout of the UV faces (the one you see in the Image window, when UV mapping) to a tga file, yo help you create UV textures for your model.
After these steps, there are faces in the middle, which were never selected and
don’t have UV assigned.
First assign seperate materials to the different parts of the mesh. Then select a material group (1 mat 1 , 1 mat 2) to apply the UV textures to.
This will solve your other problem since you are working on seperate materials you would be less likely to have accidents while working with the UV editor, (but still likely while selecting materials from the datablock. Speaking from unnecessary experience!).
Al_Capone: I don’t see why someone would like to do that, both script have fairly separate use. But of course, if they want to integrate it, no problem.
