The funny thing is, that the scene preview is fast... It renders in only 5 seconds or less. Only the texture previews need that long. Maybe it is because Vue is trying to update all texture previews at the same time - something I could very well live without. How about updating one preview after the other, starting with the texture that is currently worked on, then the mixed texture underneath and then the texture preview in the main-screen. I could very well live with that, if just texture system would get faster. Joerg
