Particle system transfer times to octane
I tried out particles in Blender for Octane and ended up with thousands of particles (grass creation etc). Rendering this in octane takes forever ... blender spends minutes to transfer the 20-30000 particles of grass blades. I guess this is normal?
I don't remember it taking that long when I tried it out before. Make sure that the mesh type for the particles is set to "Scatter" that way they will be instanced.

Yep, I just tried it with 54,000 particles and when the particle meshes were set to scatter it transferred in about a second. With them not set to scatter, I waited a couple of minutes and then ended up killing Blender and starting over.

I haven't tried grass, but hair rendering is definitely slow; it takes about 40%-50% longer than in Cycles (and yes, that's when mesh is set to Scatter).voon wrote:I tried out particles in Blender for Octane and ended up with thousands of particles (grass creation etc).

Octane's results are obviously much better than Cycles, though.
