As I'm getting into modelling SM with Maya, I'd have a few questions for you :
1) I understand that UnrealEngine speeds things up when using a grid to snap to powers of 2 coordinates, but is it relevant for SM created with Maya, as they are handled by the graphic card ?
In fact, I use a 8 uu grid under Maya, but when using scale tool, vertexes no longer snap to maya grid... Does it impact performance ? Can I use the scale tool, or must I do scaling "manually" by moving vertexes one by one to be sure they snap to grid ?
2) I'm putting my hands on UV mapping & texturing... How do you guys determine the size of the UV texture ? I've taken a look at some SM done on original maps, but I could find any kind of rule... Are there any rule/habit like some "128 pix <=> ~64uu" correspondance, or is it just by trial/error ?
Thanks for your help.
