UV editor - texture resolution

Hi McNeel
I’ve been meaning to ask this for a while: When doing UV unwrapping in the UV editor everything looks fine; hi-res preview of the texture correctly applied to the geometry. As soon as I click Apply, the texture starts to render, but stops after a few iterations, leaving me with a very crude-looking texture. Is there a setting for getting the same quality I’m seeing in the preview?

Sorry @pascal, but I don’t know which McNeel employee to tag on this issue, so I’m tagging you… as usual.

@Normand The polysurface in your model shows very poor texture quality. When UVEditor is running you’re seeing the mapping primitive mesh that defines the texture mapping, so I guess it is perfect by definition. But Rendered and Raytraced display modes and also RhinoRender use texture baking and that makes texture quality dependent on the utilization degree of the texture packing of the polysurface. In your model the packing is very inefficient and that drags down the quality. I working on adding code to check that baking is disabled for these kind of objects.
