Hi all!

I was wandering if it's possible to render splines with an emitting material?

I have a scene with a spline object with a octane tag on it. "Render as Hair" is check on the "Hair" tab.
What I want is to turn the spline in a light source.

I understand that since the spline is not a geometry it makes sense that the emission shader won't see it,
however I was hoping maybe there is a work around.

PS: Just to use a sweep nurb and generate geometry from the splines doesn't work for me cause I have LOTS of splines and will kill the viewport and octane.

Have you tried the blackbody emission with "Surface brightness=ON"?

Answer is NO for this case from devs. Hair primitives are not supporting the casting of any illumination.

Link the trails to xpSplineMesher - there the emission will work - no more need for the hair tag
