Hi people,

After a long absent from cgtalk and from cg, I am back and need your help. I am trying to use the mix8layer with fast skin SSS, I have tried multiply times and multiply connections, pluging the lightmap in the SG of mix8 as well as SSS SG, but no luck. I am using Maya 7.0 and downloaded mix8layer 1.1 from highend3d.

What I am asking for is a basic sample scene where somebody has the connections correct. I know that this can be done but everything I have tried has failed. Just a small scene with a sphere or cube with mix8layer connections setup using the mi SSS fast skin.

I have also searched multiple times on this forum for the key words Mix8 and mi SSS but all there is, are brief explanations no real examples to download and view.

Thanks

This is from my archive...sorry I just copy paste and do not get info about the author of this pic and text

When you have finished (mean finish the sss setup with lmap), plug the "misss_fast_lmap_maya" in the Light Map Shader of the Shading Group from the mix8layer and plug the misss_fast_simple_maya in a layer. Should work.
Now you should link the Misss_fast_simple_maya to a layer of your mix8layer shader (with screen as blendingmode).
Then navigate your way to the Shading Group node of the mix8layer and apply a Misss_fast_lmap_maya to your Light Map Shader of your mix8layerSG.
In the lightmap slot of your misss_fast_lmap_maya shader, type "mentalrayTexture1" and press enter.
Now it should look like this and it should work:

no it dont work whatever I do. I think its MR its been buggy on me for a while. The render refuses to render, it says:

API 0.0 error 301031: call to undeclared function "mix8layer"
API 0.0 error 301036: while defining material "mix8layer1SG": undefined shader "mix8layer1"

Whatever that means, anyone know how to fix it. Ive put the mix8layer stuff all in the correct places. It just wont render on me.

Something wrong with your installation ...your Shading Group node cannot undertstand what mix8layer is...check again your installation step by step

Good luck

Thanks again, ghostlake114 and leha_sokol.

In my haste to install this mix8layer I forgot to edit the maya.rayrc

update the maya.rayrc with the following lines::
link "{MAYABASE}/lib/mix8layer.{DSO}"
mi "{MAYABASE}/include/mix8layer.mi"

Working now, thanks. :beer:
