So, I’ve been messing around with the plugin. A LOT. It’s possible to export from Maya, you just need to have all curveShapes under one transform node.
But there is other problem. The same steps that work on cube mesh, do not work for cillindrical mesh. What could be the reason of it?
I’ve tried remodel cube to shape something similar of cillinder, and only SOME splines stopped being picked up by shader! So it’s partially bald, although I’m remaking and reexporting splines anew. So it looks the shape is actually affecting if splines work or not, which I believe should be a bug or something.
I’m looking forward for new implementation of mesh controlled styling in 4.19. But I also hope it would work in 4.18 as well.
P.S. It could be much easier to debug if we could see splines in engine. HairWorks have this option.
