In general, the drawing and painting tools are quick to make changes permanent. Perspective is far from the only issue with Paint 3D. Without a rich set of camera controls, tool changing shortcuts, or many hotkeys to speak of, this process quickly becomes tedious. As the object count grows, you’ll find you must pull each object out in front of the rest, do any work on it, and then rotate and slide it back into place. Regarding Paint 3D, I'd be interested in your comments on my post here:īasically I was keen to have a workflow of export from Sketchup, paint in Paint 3D, import back into Sketchup.That’s not really an issue for single 3D objects, as you can rotate the object in place to re-shape or paint it. I haven't posted my exporter anywhere at this time, as I haven't implemented matrices (I am currently multiplying all the geometry in the model by the combined matrix in sketchup during the export), and also haven't implemented shared meshes (components in Sketchup).
