2. Pixellate: No...
No ? it doesn't work ?
ok I leave mask, but I would like to improve rotation control, it's not very easy for now. I've take a look at aRTifakktory "the amazing jpeg filter of death" (this is a comment in code lol) but i'm not sure that I can reproduce this effect, morehover, here, I only use shader code for those ipp, with the same basic structure so it's very easy to add some different ipp, just need to copy/paste most of the code and concentrate only on shader code to produce the fx, aRTifakktory is not a only a shader code so I can't use it here, and it need some more time to reproduce, but i'll try to reproduce this effect in shader code.
Thanks for your test file, I've modified textures to be more precise and added a big inside cube, it's better to test texture clamping on borders.
