To Ivan: Remember I’m talking about ascii 3d software scene files, for models, materials, perhaps animation and even rigging. Not bitmap graphics in any shape or form. This is purely for sharing 3d scene files between the artists working on assets for vcmi. The bitmap graphic files are created upon rendering, which happens last. Most likely post work is required after rendering (i.e. photoshop etc), so this is when I’d recommend using another sharing service/location rather than SVN for bitmaps. However, probably most artists here will do the post work after rendering themselves (I know I will).
Hope this clarifies a bit.
