Hello there i've been fooling around with the new materials in LW 9.2 and i found that diaelectric and conductor are very easy to play with. BUT SIGMA HOOO my god this is really a pain in the .... for me. Firts it takes an eternity to render and then it does not look right, i'm looking for a waxlike material. Can any body share some settigns, so i can study them and see if i can get something good.

Thank you :thumbsup:

I feel your pain claudioarchi, every time I've messed with it I can never get results anything like the examples I've seen in NT's 9.2 gallery.

I agree, it takes AGES to render, only to find it looks nothing like you want. And because of how it renders, you HAVE to wait until it's finished!

I have given up on it now! Maybe when some better documentation of what the controls do and HOW they affect the material come out, I might have another go.

Thanks Pooby, I'll try that!

for the Sigma ... put a light near the wax object... change the specular and roughness values as you want and turn down the translucency a bit then play with the distance until you get the best sss effect.

or as pooby said use Simple Skin it's really simple and better to achieve sss with it :)

Try making a brighter backlighting than a front lighting for SSS surfaces. You'll see the effect much better.

Yeah, I still think sigma is the best for rubber, plastic and wax.

This might help.. It shows some simple skin settings for wax.. I only spent about 2 mins on it so that should demonstrate how simple it is.
