What's the biggest I can stretch a mess to?
Soooo exactly how big can I stretch this thing to?
Ultimately any mesh can be technically stretched to 64m squared. This means 64 meters in all 3 directions (x,y, and z). HOWEVER!!! We really don't recommend doing this unless you really need to. Biggest disadvantage of it is that a 64 meter mesh that is 1 object does not equal 1 prim like a 64 meter sculpt does. This means, that you could easily end up pushing well over hundreds of prims (yes seriously) when it's blown up super huge. Because of this, we greatly recommend adjusting the size of your mesh to keep it at the optimal size not only for looks, but for usage as well as to save prims.
