Hello again.
New test with separated renders.
(yeah, I know. The absolute best would have been to let all of them cook
to SL 10 and compare the time it took, but I dont got the time to do it.)

SSS-Settings:
Absorption: 0,10
Scattering: 0,10

Materials with SSS:









Materials without SSS










Id like to thank "4 HeRo" (and JDHill for the tips) for The material with the transmittance-map.

Settings:

sss looks great!

how long did they render / which sl?

EDITED
In my oppinion, the double-sided SSS looks great, while the single-sided looks like sh*t (When emitter is on).

It cooked for about 1 hour and reached SL 11. (Multilight)

Im not satisfied with the emitting trough the transmittanceMap yet, but I will try to add red color to the map and hopefully it will transmitt red light to.

well - depends on your goal. i don't think the single sided sss is too bad, especially with the sky on.

would be interesting to know the rendertimes sss vs transmittance, and maybe you could use the same modell for all tests. it's hard to compare because you switched single / double inbetween.

If I got time, then I will.

hi sunlight rocker

great tests!

can you share the sss settings of your test?

thanx alot!

This is a great material to MXMgallery

So we don´t need to add a layer of subsurface to create a SSS maaterial

No, thats not the point at all with this.

In that tread, Im creating a house of glass with curtains, and if I render a dayscene the fabric looks good, but when I turn down the daylight, the curtains doesnt have the red color anymore, and therefore I made this test to see how I should setup the material in order to get the red color. And the best way seems to be SSS with a doublesided mesh.

Yes i saw... very nice

Can you explain me abou singlesided and doublesided mesh.

Thanks

Double sided = thickness
Single sided = flat

The doublesided object has therefore more than double the polycount.

But you must give that attribute in C4d (in my case) or in others platforms, we don´t make that attribute in mxed ? How we attribute thickness or flat side is in material attributes in cinema 4d or mxed?

Thanks

No, thats right. Its the model itself, not the material. I use maya And model my object with single or double sides.

Everyting in real life has two sides. If you paint a wall, the paint has two sides, and then comes the wall...

That's a nice comparison SunlightRocker, I have been investigating the best method for doing curtains in a complex interior scene by myself quite a bit by now. I am atm doing very well with single sided clipmapped geometry. I tried doublesided SSS in advance and it produced good results too when using pure skydome lighting. But it looked horribly when hit by direct sunlight. I'll post my results some time next week.

That would be great, cuz Im not satisfied wit the results I have right now. I need to do more test with other settings. Would be great to see what You came up with.
