What is the best way to go about exporting geometry to be used in Maya that has been fractured and be able to keep the “Inside” and “Outside” groups that are created.?

I have tried a few methods and none seem to work. Could it be because at frame 1, the groups do not exist yet, only once the geo actually fractures?

From what I have read, FBX doesn't support groups, ABC doesn't seem to pick up the groups at all, and i'd rather not use Obj's for each frame

I think you can't export your fractured geometry to Maya with FBX format ,Because FBX support keyframed animation objects ,But fractured Geometry is not keyframed animation !!!

So you need some other formats that support point cache data exactly like Alembic Format :idea:

Alembic format can be support groups like “Inside” and “Outside” It's work perfectly in the Nuke ,But I don't test it in the Maya :?

The other good way is to use Houdini Engine ,You can simply export your fractured pieces with it's own groups to sequence bgeo format ,finally create a simple Digital Asset with File SOP to read sequenced files and use this DA in the Maya with Houdini Engine to read bgeo files and use “Inside” and “Outside” groups perfectly 8)

Oh man , I was wrong ,you can export your cached geometry via fbx format , just you should active export cache option , but about export your groups , hmmm :? , I think you should use Alembic !
