Your the secound person to have that happen with the SR3 Patch for Poser 5. raven in this thread complains about the same thing. I'm running the last SR2 patch for Poser 5 and I can load 6000x6000 textures, it does slow things down but it loads them with no error message and renders. I have a feeling that they put a limit on it in the SR3 patch for some reason. Poser 5 was supposed to run larger textures.
