Hi,

Just asking, coz I can't infer this information from the manual :(
When rendering hair - should I add the FB Hair tag besides the original C4D Hair tag with C4D material? Because the C4D hair material has all the controls for thickness, curling etc...
So the tags on a hair object would look like this (from left to right): C4D Hair Tag (with C4D Hair Mat), FB Hair Tag, FB Hair Material (in a C4D Texture Tag). Is that the proper setup?

Also, if I wanted to render splines as hair - normal C4D workflow is to add the Hair Render tag followed by Hair Material. So in order to render in FB - to that setup - I should add FB Hair Tag and a FB Hair Material?

Unfortunately I have been trying this and other combinations without any success, and FB kept crashing or simply not rendering any hair.

I am not using motion blur.

I tried different settings in Acceleration structures as well ... unfortunately nothing seemed to help. :(

The scene is very simple. The hair are just 5000 strands or so.

Please I want to stay optimistic! :D
Cheers,
B

Yes, it works. FB hair tag is not needed, there is only some additional parameters.

Splines are not supported yet, however you can convert it to hair if you need it.

Thanks for the answer.

I was trying to render splines generated from a Tracer object.
When creating Hair object from the tracer and hair from guides, all seems fine in the viewport and physical render, but FB crashes.
Next I tried to bake tracer into alembic (which worked ok) and then using that as a source for hair, but still doesnt work.
It only works when I explicitly do "current state to object" from the alembic splines, and use that as hair guides source, but that effectively limits me to static shapes. :(

Cheers,
B
