That may seem like a small thing on first glance but here’s what you get automatically when you import our FBX files with our import scripts for V-Ray: And now those scripts support V-Ray as well. It was via import scripts that we prepared SpeedTree models for rendering with Mental Ray. We’ve addressed this in SpeedTree by writing out native formats when we can (like C4D files for Cinema 4D users or 3DM files for Rhino users) and creating import scripts when we can’t. What’s more, that effort is typically repeated each time you import a model. Getting the materials correct for your particular renderer requires a significant effort. This is no small feat - it isn’t enough to simply export an OBJ or FBX file and say you’re done. One of the main challenges of developing a standalone modeling app is making sure it fits in with as many modeling and rendering pipelines as it can.
