Upon rendering an image in Blender 2.32 I get horizontal artifacts and what looks to be partial transparency on a uv mapped procedural texture. I have checked this in 2.31a, 2.30, 2.26 and 2.3 and the problem does not exist on any of them using the same .blend file. System Specs: Linux SuSE 9.0 running kernel 2.4.1 Nvidia openGL drivers version 4496 Nvidia MX 440 64 meg AGP 4x I have put up a page with sample renders done with different combinations of OSA values, the unified renderer on and off, and the render done in a previous version for reference; there also can be found the subject .blend file: http://www.zaug.netmegs.com/232uvproblem.html Hope this helps, Zaug
