Several of my V4-based characters suffer "cracked faces" in Octane. See attached render. Does anyone know a solution to this? Thanks.

Reduce the rayepsilon setting. It make look like it is at zero but it can go lower.

Yes, as noted above, the value of rayepsilon is probably your saviour

The lowest value is 0,000001. You can enter this value manually. I think the default value is set at 0,000005. But I'm not sure of that.

I've found that you have to specify a non-zero value and THEN specify a zero value for it to 'take' at the lowest value it can have.

unfortunately because of the digits limit in the daz slider, you won't see the input number; as zero is below the limit the plugin won't accept it, but the 4 digits in the daz slider still show like it was zero... to overcome by this: http://render.otoy.com/forum/viewtopic.php?f=44&t=36713

These cracks are transparent geometry, the upper looks like scalp, the lower like eyebrow, that cut through the geometry of the head.
Took me a good while to figure that out.
Scale the hair or use a deformer, and move the eyebrow geometry if thi is the case.

Hope that helps!
