The really interesting thing about USD it’s more than just an asset and scene file format it’s an open source VFX pipeline so it’s going to have a dramatic affect on how we do 3d. Importantly both big game engines have announced they’re supporting USB and according to Ton over at Blender many studios he knows well are well underway with switching their pipelines over to USD. Since the beginning of 3d software we’ve always wanted slick scene and asset transfer between applications COLLADA, FBX and Alembic were all touted as being the answer but weren’t, however, we might just have a chance with Pixar’s USD given the players who are adopting now and those who have stated plans to adopt it. When I started with Houdini we settled on using Alembic for interchange, before that we used a potpourri of formats, whatever worked. Some people like me have our own ways of working and once we’ve set up out small scale vfx pipeline we don’t tend to change unless change is forced on us. This doesn’t concern Davide in his usage. There’s nothing wrong with Objs in principle but for animation they are just a sequence of still meshes so rendering with motion blur is problematic as there is no actual changing geometry. Modern formats like Alembic have an advantage of being able to store all manor of vertex data, one of the most important being velocity to accurately represent motion blur for deforming objects.
It’s just a question of file or scene format exchange. Exporting a sequence of obj’s seems not to be rocket science, and should be a no brainier in an expensive app that has supported the actual format since for ever, but not really done any work on it since 1995 ish. Some times people have to deal with the real world out there. So although old formats are becoming less used, due to alternatives, they are not to be ignored as if they don’t exists.
Lots of people still get sent old crap from clients, and have to figure out what to do with it, or get asked to send old crap back, and figure out htf to do that.
Even old garbage formats like VRML are probably used more in everyday life, than modern formats by armies of people who are not doing what you think the world is doing. It often makes far more sense to support old, well established formats, despite their limitations, than it does to support the latest and greatest trending formats. And relatively speaking, not a lot of software that supports so called “modern” formats. There is a lot of old (and new) software that supports obj,vrml,etc.
