hello,
i am trying to make LDPE foam material, but i'm afraid that white dots will not disappear.
Here is what i tried:
- created a normal map from scan of the foam sheet.
- used SSS polyurethane preset (with desaturated the colors).
- tried controlling the shininess with single BSDF (not good enough), then with a gloss layer with forced fresnel on.
Two layer approach seems to work, with gloss layer in additive mode.
Could use some help to improve this:
- How to avoid the white dots?
- any tips to improve the material appearance and reduce render time?
Following is a photo of the material and a test render at SL 19.7:
thanks,
raja
