Arnold won't render surface textures

[Anonymous]

Hello All,

I have created a texture for an eyeball using 2 aiStandardSurface linked to a BlendColors node, but when I try to render it in Arnold, it shows up as a black sphere on a white background (I have a skydome and area light in the scene). Also, a warning shows up that says, "Warning: [mtoa] Could not link aiStandardSurface1 to blendColors2.input1."

Any ideas would be appreciated!

Thanks,

Josiah

Standard Surface doesn't return a color, so you cannot use a node like BlendColors.

You can use Mix Shaders with Standard Surface

or blend the textures first and then plug into standard surface

Hello Stephen.Blair

Hmm, that's odd...because I watched this tutorial that used BlendColors and it worked pretty nicely: https://edge-cgi.com/maya-tutorial-how-to-create-a-realistic-eyeball-with-arnold/

Thanks!

That's an old tutorial, using an older Arnold.

It uses aiStandard, not aiStandardSurface.

In Arnold 5, Standard Surface replaced the old Standard shader

Aahh...I see. So what would using a MixShader node with my two aiStandardSurfaces look like? 

Thanks!
