"much easier with symmetry :) also, there's ridiculous 500 tri's limit and only one slot for both weapons." The one slot can be two different weapons. 250 to create a weapon is enough.
>No pictures of the actual sculpt. >LOD 0 is 500 tris Something tells me he had to do a lot more texture work that he should've. I'm also going to use that quote as a copypasta, that language is hilarious.
The workshop tech page says the 'weapon' must be bound to r_ and left_weapon bones. So yeah, it looks as though you need to upload one complete model for both sides. It has a poly budget of 1000 tris which is pretty high for weapons. 500 tris each is still a decent budget.
