I love using lw, but lately have been learning xsi at school.
Somethings I really like about xsi:
- select loop <–lw8 has this now
- select range
- The uv tools in xsi are sweet. I love how you can tear your pieces apart and it color codes the edges of them so you know what they attach too. The heal tool will weld them back together and also scale it to fix the pieces together nicely. Also, island select is really nice. If you end up with pieces of your uvs stacked on top of each other you can turn island select on and by picking one point on the uv it will select the whole piece.
- I also enjoy being able to use the Left Middle and Right mouse buttons to move along the x,y, and z axis’. I think that you can do this in Maya and XSI.
That is all I can think of at the moment and these things I really like in xsi.
