hi lukahsi,
The red bits are (if we’re talking about the same thing) the texported segments of the mesh. Texporter is a plugin that unwraps your model and makes an image based on the uvw coordinates with all the polygons outlined. Then you can take that image and paint over the top of it using the lines from the poly’s as reference so you know what part of the model it is you are painting on. very useful!
Is that about as clear an mud?
ps,
