Ummm… Do we still not have the Blender equivalent of MetaMesh https://www.youtube.com/watch?v=ctESAMUQYv8 in Blender? :-/ I just had to jump over to LightWave to merge/weld two meshes together, which kinda sucks, since I hate working in LW anymore and takes me forever to remember my old shortcuts etc… In other words: are you telling me that Blender still can’t blend two meshes together, in a way that is an automatic process? I’m ready to plunk down cold hard cash for any addon that does exactly like the 3RDPowers’ plugin MetaMesh for LightWave (must be able to do both Union and Subtract)!
If Blender indeed does not have this ability in any addon, some enterprising person needs to make this, pronto!. I have money waiting for you.
