I have Vascularity For Poser by Zev0 & draagonstorm @ Renderosity, it's pretty good but doesn't work with Octane. I can use the displacement maps, but I haven't figured how to add the diffuse map. There's a material mix, I'd have to add a third material with some kind of transparency but I don't know how.

The bad news is that the veins are not on a transparent background, if they were I could just use Photoshop and apply over the character's skin. Tedious for many characters but doable.

Dear Scott,

got your e-Mail as well, please check

I think I got it! I didn't see the Merchant Resource before. I found it, that has the vein diffuse and displacement maps on a transparent layer in PSD format as needed. Only had time for a quick test, but I think it works!

...same issue here. Can't get a proper render using Redspec and Vascularity.

The problem is, that we didn't design the RedSpec TGX tailored shaders with displacement mapping in mind, because it was chewing away too much S/P when being used on every material of a character back at the time.
To this date, displacement mapping is still one of the most performance-dropping features of Octane, which is why we rolled with Bump and Normals.

It is - however - very easy to add Displacement mapping like the Vascularity products are using it.
Simply open a material inside OctaneRender and find at the very bottom the Displacement node.
In here, select the corresponding texture for the material zone and set the Detail to 4096x4096.
Now set the Height, to something around 0.001 and at he Offset to -0.0005.

This should give you a good starting point from which you can further tweak everything.
Always remember, that the Offset value should be about half the amount of your Height setting but in negative.

Hope this helps, if not, don't hesitate to ask

Thanks again TRRazor. I forgot the offset, I'll have to try with it.

MyRho, the PSD files work well. I prefer them actually, you can tweak more in Photoshop, then when done, you're done for that character in future renders. I have the original zips and PSD file for backup of the original skin. With Vascularity, I was keeping a text file of values I've used and/or using a default for my characters.
