Ah, I had 3.1.0, i'll get the newest version and see if it works Edit: Hmm, no, the program crashes at the same point (calculating normals, [mip level 0], just after halfway on the progress bar) with version 3.1.1. However you were right about the dual monitor thing I emailed you about, I had 2 -> 1 instead of 1 -> 2
