Great, I should have tried it last note but I haven't. I'll try it tonite. So I just click on the Texture button on the immediate right of Bump Value and then out pops the Hypershade material window and I can choose Fractal for the bump map (I'm creating skin texture for a head which uses misss_fast_skin). I had tried it on Lambert which is assigned to my head and it works just fine but the SSS is not there and the skin looks like plastic or wax.

Funny though, yesterday nite when I rendered my head with misss_fast_skin, there were weird small red dots like when the lighting intensity was set too high. I checked lighting but it was ok.

Just wished that that 'famous' dragon tutorial on SSS had provided the sample Maya binary file which I could then download and experiment to see how the author used misss_fast_skin.
