@ethiopia I guess directly, they can't be exported to Daz. I haven't tested it, but I "suppose" that they could be converted to the .vbd format (which Daz does accept...) or an .obj plus an .mdd, or an alembic.
I'll take a look, although I don't understand much about Unreal...
But the file, if possible, would have a "few" Gb... 😀
That's interesting reading and I'm intrigued by the new NanoVDB from NVidia. Now all we need is for Studio to support it. I assume this would be a part of Iray?.
