You can use the backfacing output of the geometry shader node as a factor to mix two fresnel nodes. The input of the second fresnel node should be 1/IOR to get the correct shading on the backface.

Oh nice. That's smart I have not thought of that. But it makes perfect sense! Thank you for sharing this option 🙌

Amazing tutorial and the node setup for the fake shadows is genius. So far I have either used what Blender gives out of the box or for interiors I have removed all shadows to increase render time. Now I can have the best of both worlds. One problem that I still have is that all the faces of the mesh are visible as soon as I increase the volumetric density to a value that gives satisfactory results. (5 cm large object and a density of 500)

@SilverwingVFX 8 ай бұрын

Thank you very much for your super nice comment. I appreciate that you fount it of value. About the density and seeing the faces in the SSS. As far as I could tell this is a unfortunate side effect that I did not find a workaround yet. The only thing I found was to increase the mesh density. Also. I forgot to mention this in the tut. But the thicker the SSS is, the less difference there is between the random walk and the volume method. So if you want to reproduce super thick SSS (while theoretically the volume method is still more realistic) you might be fine just using the Random Walk.

Thank you very much for your comment and your input. I will think about it. Though it might be a bit boring, since my lighting setups are usually super simple. Mostly one HDRI and one or two lights 😇 I would generally say it would not matter because lighting is lighting 😄 It`s the most universal thing in 3D. But what software would you prefer?

@@xff3959 What's the outcome you had? I have modeled my syringe to scale. So it's really just a couple of centimeters long. This can make a huge difference in the way the shaders behave! If you are modeling to scale and also apply the scale at the beginning of shading (so you have a scale value of 1) then you should get the same result then I have. It of course could also be other things. But scene scale is the most likely!

@Just3DThings 8 ай бұрын

This is awesome as usual I think you might already know it but if not this can be useful , in the math node there is a radians to degrees and degrees to radians convertion. If that helps : ) Or you can simply type pi/2 in the math inputs to get that 90 degree equivalent in radians

Hi! Thank you for all your tutorials. I've repeated your tutorial step by step, even subscribed Patreon to investigate the source file. But I can't still understand: what's the necessity of such complex node system if the same matte plastic "sss" result can be achieved by just Principled BSDF with Transmission 1.0 and Roughness any you like even without enabling SSS. Could you please explain?

@SilverwingVFX 8 ай бұрын

Thank you very much for your comment Egor. And of course also for subscribing to my patreon 🙌 There is a distinct difference between SSS and roughness. SSS happens inside the volume of the object. Roughness happens at the boundary condition, when the light enters the material. It can appear to be the same in certain situations. But is a totally different effect. One is the effect of frosted glass. Where everything you see through the surface looks blurred and out of focus. The other is the one you have e.g. with milk. If you take some milk and mix it with water, you get a milky murky substance that looks cloudy. But the surface of the milk water mix is not rough. If you mix your milk with enough water, you can still see through it unblurred, but the fluid appears cloudy. I have made a tutorial with almost the same topic for octane that I also mention in the video. If you watch this, I have some real world examples in there. Maybe this makes you understand it better: kzbin.info/www/bejne/nHa8enykgNJpo6M

@egorsorokin2760 8 ай бұрын

@@SilverwingVFX I've checked the second video, thank you! Much more clear now. But now I have the second question as I'm not so good in Blender SSS: the Principled BSDF has the SSS slider. Can't we reproduce the same effect just with the basic sss settings of Blender materials? Or they are too poor in comparison to Octane, so we had to recreate the whole light physic manually?

@SilverwingVFX 8 ай бұрын

@@egorsorokin2760 Thanks for checking back. Glad I could help! About your next question. I think I show this in the video at 2:15. Using the SSS in the principled is a diffuse kind of SSS. We will miss all refractions through the object. As soon as you introduce some transmission, you are loosing the SSS again. If you find a setting that works, feel free to share it. It can always happen that I overlook something.

That looks insane! I will test myself, but how does it compare in render times to the regular SSS?

@SilverwingVFX 8 ай бұрын

I just had someone else pose the same question. Tells me I should have done a test. Which I unfortunately did not. It also really depends on how much ray depth you give the volume. I have quite a bit of render power (3 x 3090 1x 4090). So one frame of the turntable rendered in 50sec in 2560 x 1440 with Depth of field and without denoising which I think is quite good. I can remember rendering some Lego blocks using this technique around 5 Years ago and it took ages. But nowadays we do have hardware multiple times faster as well as a updated and vastly more speedy CyclesX which really helps to make this option vaiable. If you do any tests on your own, I would welcome if you share the results. Also I did not find any other method to make convincing milky transparent plastic. So for this, there is no competition 😇

@@SilverwingVFX Making plastic looking right with Cycles is insanely hard, especially since they took away the transmission roughness (Why?), but this technique does it really well in my opinion.

@SilverwingVFX 8 ай бұрын

@@Skovidesign As a long time Octane user, this is how SSS works in Octane, and I always liked that approach more then the surface approximation SSS. I did not even know they took away the transmission roughness. I think it is linked now with the overall roughness as this is the more realistic thing. As in reality the surface roughness is of course linked to the refraction roughness as well. But I might be interpreting stuff wrong here. Not to knowledgeable about the old Principled shader. With the setup I show I think I have everything that I need to produce good SSS and foggy / transparent / translucent plastic shaders for now ✨

@FrozenDozer 8 ай бұрын

@@SilverwingVFX Is the surface roughness really linked to the refraction roughness irl though? Can't you take a plastic that is very milky and just polish it like crazy? Sounds to me like this would give you low surface roughness but high transmission roughness.

Nice! What´s your estimate Raphael, as a 10 year C4D generalist, how long would it take to be confident enough to tackle the first projects using blender? I mean... in a way that feels more or less save? Blender seems so much different but I´m so annoyed my Maxon. Need to make the switch now.

@FrozenDozer 8 ай бұрын

I know you didn't ask me, but I switched to Blender around 2 years ago and to feel safe it took me about a year. I didn't do Blender 24/7 though so if you REALLY spend your time learning it'll be much faster. At this point, I prefer Blender. It does things it's own way, but imho it's often the better way. It's more technical though.

I have tinkered around with Blender here and there so I already knew a bit. After I did my spare time project in Blender I would take on work for Blender now. It took me maybe half a Year and 1 month of every day 8h project work to think that I am ready. I will still be slower in a lot of aspects than in C4D for now. But in general I am comfortable with the basic pipeline !
