There are so many out there, the lit would take us forever to compile. I know lightwave is safe, but DeepUV is a uv editing program, used by many poser content artists. All it does is change uv mapping, if memory serves, and that means it does not mess with point order, but also, it cannot create morphs either. UVmapper pro is another UV editor, and again is NOT used for creating morphs. (although it can be used to fix some export issues) Plus another consideration, is price. Not many people are going to invest $1500-$4000 for a 3d modeling application just to create some morphs. Rather then a blanket "what all programs can" question, would be "what program do you use", or I'm considering x,y,z.. which would work? questions. It's kinda like asking which is the best grpahic editor for making textures... there are SO many to choose from.

Way too many people take way too many things way too seriously.
