I have been noticing texture maps getting smeared on occasion, and in what I would consider an odd manner. Often on picture frames, when it fails half of the surface will be fine, but half will have an approximate 45 degree smearing. Bellow are some screen caps of something similar, but this example doesn’t show the half and half-ness of what I’m seeing with picture frames. The picture frames can usually be fixed by resizing, or by closing and opening Rhino (which makes sending in an example hard). In this example, applying a bump map seems to make the bug more repeatable.
Anyone seeing something similar?
