Do you have this problem with other objects in Z, or just one particular model you’re working on? Maybe check out some other quick native polymesh objects.
I seem to move points across screen with no problem. Perhaps it has something to do with the worldspace scale of the model? Like if a mesh is just really, really big it makes the space a vertex can travel in a single stroke short in comparison? Perhaps youre zoomed out really far on the model when you do it, which would also make the distance it could move seem really short, if its an absolute value?
[edit] I just checked this out…if I’m zoomed out really far on a mesh, yeah…it makes it seem like its moving a much shorter distance. I can see how that could be annoying in some situations. I dont think its a bug, so much as an unintended consequence of making the move function into a brush. I suppose there needs to be an exemption on the stroke limit for the tweak brush, if such a thing is possible.
