Hi all!
Well, I’ll try to hold my tongue as I write this post. It’s late and all I really want is to succeed with ANY SSS shader at this point. I’ve tried SubScatter and while it has pretty good results, I’m not getting that true SSS effect you see in “The Incredibles” and “Shrek 2”. I’ve downloaded the shader pack from Alias and installed it/them and you practically have to have a college degree to figure them out (at least that’s how it is for me). And now the one you all are touting as the “it” shader for SSS - Diffusion. I’ve installed everything as they are supposed to be but when I go to render in MR, I get nothing. In my Script Editor it keeps saying // Info (Mayatomr): Aborted //. [size=2]I’ve tried Point Lights and Area Lights and Directional Lights and honestly, I’m about to give up. I don’t have the time to read all though all of these forums and pour through various others to get the answers I need. Let me show you an example of what I’m coming up with in SubScatter. Everything else is looking okay but I can’t get that “light behind the ear” thing to work. Mark Davies himself said this… [/size]

[size=2] "This is happening as a result of the thin geometry of the ear. Our rays
fired from the light sources are returning bad distance values and
leaving
areas darker than they should be. You can try a few things:

  1. thicken the ears. this would only be to see if this is indeed the
    issue
  2. map the ‘Absorption’ parameter. this would be a greyscale painted
    map
    that isolates the ears as white. you may need a setRange node to remap
    the
    values to greater than 1." [/size]
    [size=2][/size]
    [size=2]I’m lost. I have no clue what I’m doing. I just want to achieve the effect and just move on to my next step in getting my first movie made. This is hard stuff! If anyone can please send me in the right direction, I’d really appreciate it. Thanks![/size]

Sorry, maybe not what you asked for but - I prefer the misss_fast_skin shader instead. (I don’t know the answer to your problem because I switched quite a while ago.)
You really should give it another try, for instance none of this problem with the ears. I think anyone who can assemble an IKEA shelf from their instructions should be able to install and use that shader :slight_smile: provided you read the tutorials of course, there’s one by Jozvex on installing, and a couple over at Lamrug.org (sp?) the links are in that misss thread.

Also, always check to make sure that things like cast shadows and visible in relfections/refractions is truned on. Its the little things that can screw you the most.

Hey, they do happen. Just wanted to share with you guys the results of my latest renders. It just kinda happened. As I mentioned on a different thread… one part DirtMap, one part soft ray traced shadows and 2 parts SubScatter SSS shader and voila! I’m quite proud of this render. Any comments?

Thanks,
Russell

I asked this in another post on the site but I wanted a second opinion so I’m coming here. The answer I got for my question was this: “To have better results you should paint texture in photoshop to localise your sss…” First, I have no idea how to do this. And letter number 2, why can’t we just use the SSS shader to get the SSS effect instead of using other software like PhotoShop. Well, here was my original question… - maybe this is just an anomoly but it can be remedied, I’m sure. Can you explain why around the edges it seems more pink. my Scale Conversion settings are at 45.00 and the Fall Off is at 2. Thanks in advance!

I love this shader, and maybe I haven’t looked hard enough, but is it compiled for Maya 7?

Nevermind I’m an idiot!!!
