Hi,
I've been getting into Blender recently, mainly for it's Cycles engine and NPR capabilities. I'm experimenting with how to export hair from C4D to Blender for rendering. So far, my best attempts were generating every single hair as a spline in C4D, exporting as Alembic, importing to Blender, then changing thickness of the splines to become visible and rendering with a Principled Hair shader.
However, the generated Alembic file has an enormous size and animation playback in both programs becomes very slow. Moreover, I found that spline thickness in Blender is uniform, with no tapering like in C4D. This makes the hairs look like noodles.
So my questions are if there is a way to optimize the Alembic file to be smaller and how to assign varying thickness profiles to hair strands in Blender just like in C4D. Could there also be a way to just export the spline guides and then have Blender use them to construct the hair just like C4D does?
Any advice would be greatly appreciated.
P.S. generating hairs as geometry exacerbates the performance issues by tenfold. Spline seems to be the least storage-consuming so far.
