Displacement Maps not translated to Octane

[morphious2013]

What happens to the displacement maps in Octane? They provide details like veins on human skin. How do I incorporate them into octane materials tab? Thanks.

Nevermind. Under bump, I replaced the "bump" texture with the "Disp" texture. Now the veins are back. Thanks Me. LOL.

well actually, doing that seems to lose other details the "bump" texture provided. Any ideas how to have BOTH bump and displacement maps in Octane? Thanks.

You would need to merge the bump and displacement maps. Use a mix node for this - with the bump in texture1 and the displacement in texture2.

I tried that. I changed the bump node to "mix" and added bump in 1st and disp in second, but only the bump shows up. So I switched them, and onkly the disp shows up. Seems the second texture cannot mix. I tried Texture, FloatImage, FloatTexture, and same results. Is there another setting I am missing? Thanks.

You can adjust the proportion of the resulting texture of the mix by moving the "amount" slider on that node. The bump and displacement maps probably have different contrasts, so one will be stronger than the other, so just move the "amount" slider until you get the right result.

If you want a very high quality render - you may be better off mixing the dump and displacement maps in photoshop/Gimp, where you can separately adjust the brightness and contrast of each map - then using it in the "bump" pin. But the "mix" ode should get you a 90% result.
