Ornatrix and Embree for hair

[RichardBlank]

It always gives me a warning for invalid normals. Is this a problem or can it be ignored?

[vlado]

It's not a problem for the rendering, but the warnings do slow things down.

Can you get me a scene for this to support@chaosgroup.com ?

Best regards,
Vlado

I will send the scene.

Vlado, we have been having similar issues with Ornatrix, here is a sample file you may download.

Thanks, it's embree related and we are looking at it.

Nkal, actually your issue turned out to be different - it occurs when you use randomized length of the hairs with relatively short hairs as base and of course Embree. Anyway, it will be fixed

I will send the scene.

Hi Richard,
