Hair Material Problem Tweet

I am not sure if this is a general Octane or DAZ specific problem so i post this here as well.

I have a problem with the DAZ hair material.


(The IOR is the default value of 1.55)
This is how the hair looks with only and HDRI, everything is fine:

And this is how it looks with 2 light planes (from above and the side), hair is way to specular:

This is the material (IOR is default value 1.55):

The problem stems from the plane above i think, here is an image with just a plane over the figure. I toned down the IOR to 1.1 but this is still way to specular no?

I think it will be a challenge to get the Octane Hair Material to look correct on that model. That material was specifically designed to only be used on splines or curves, and it assumes the underlying hair geometry is such.

I have not had much luck getting good results when using it on hair models consisting of transparency mapped planes, though it does look decent on dforce hair.

huakiami is correct - the Octane Hair node is for stand hair, and your model has transmapped hair.

Oh I didnt realize its for strand based hair. That explains the weird look. Thanks
