Both together, Polys and NURBS, integrated into EIAS.
I’ll repeat an earlier post, XSI and Maya (and most other applications) have full modeling capability within the core package. Using an outside modeler is the user’s CHOICE, not a failing of the core package.
Modeling within the application allows for creating blend shapes, morph targets, and smart skins. It eliminates many, many, issues with basic workflow like names, scale, orientation, vertex and face normals, etc. When you can get to the vertices, you can UV Map, bake illumination, bake out procedural textures.
Despite EIAS’s advantages in render quality and speed, without a built in modeler, the program seems incomplete, and falls behind.
lol. Of course it would be nice to see everything integrated into a single package and do all the things you’ve stated…but that could take a while to manifest and we still don’t know how well EIA’s framework would support it. I’m just curious to know if this kind of separation of technologies could be beneficial somehow.
