I can’t replicate that with or without packed textures. Switching from Blender render to Blender game didn’t make a difference. Tried today’s build, Blender 2.7.5 e2c412f Linux 64bit and latest stable 2.71 with factory defaults. Nvidia graphics.
Thought that maybe it lost track of the textures for some reason but then that’s not it because the roof is different color than the walls. Maybe try again with factory defaults and see if system console outputs any errors.
I just read the developers are refactoring colors and floats to make the compositor OpenCL more memory efficient.
There is no reason to use 2.7.2 yet, it is not ready. Just use 2.71 and get your work done and forget about the pie in the sky until you hear the dinner bell ring.
Well, some of us try to test the dev builds and report bugs in order to avoid ‘a’ releases. Rolling back on my machine and testing seems to indicate it started happening around when the GSoC-Paint stuff got merged.
