Generally you can select the Mesh in Maya you want to transfer and use File->Send to Mudbox->Send as New Scene Transfering your Mesh from Maya to Mudbox

When you restart Mudbox, it will create a new 2015-圆4 directory with default preferences.The only reason to keep the tmp_2015-圆4 directory is in case Mudbox is unable to regenerate a fresh directory.

To restore Mudbox back to it's default condition, go the C:/Users//Documents/Mudbox and rename 2015-圆4 (assuming you are using the 2015 version) to tmp_2015-圆4. Not even sure if what I'm trying to do (have trees in an Arnold render) is even possible.This is intended to be a very quick basic guide to texturing with Mudbox for Project 2 Resetting preferences in Mudbox I can get a realistically lit scene with Skydome lighting, but the trees all look like collections of small rectangles. I can have trees in Maya Software renders, but cannot have a Skydome light, which is an Arnold feature. It seems as though many effects are mutually exclusive in Maya. Is it possible to restore the former look of these objects, so they render looking like trees (as was the case with Maya Software render), and have I used the wrong procedure to do the conversion and thus lost all of the attributes of the tree objects? It appears as a black and white or grayscale collection of rectangles attached to branches. I've done that, and the 'object' appears, but looks nothing like the tree it appeared as in a Maya render. What I read is that to make them render in Arnold, they need to be converted to polygons. I realize that Paint Effects are a post processed effect in Maya Software renders, so they apparently don't render in Arnold.
