liquid gel caps material HELL

[lukx]

Does anyone have any tips hoe to make this kind of material?!


This is the close I get... with translucent hybrid.. but it's still isn't it.
It's too dull
Whatever I do I can;t get this orange pop with bright yellow blinks inside.

Caps are just single faced objects. I was trying with shell but it's even harder.

I don't think materials are the problem at this point. It looks more like a lighting issue and geometry thing than anything else.

You need to get some light behind the bottle and pills, and you may need to turn on caustics to get some of the hotter spots that are in there. Mostly you need to create a light source ( area light, or lumigon/light plane with an image map etc.) behind the pills that has some variation in it and that will probably give you most of what you need for light.

I would suggest making the geometry more accurate to the reality if you want to get realistic internal complexity in the material like your reference. Make them shelled, and create a "liquid" inner object too. This will give you more interesting and realistic refractions and with the right lighting should do the trick.

OK I will work on geometry, because there is light behind. But I'm not sure if I should still try using translucency or not.

So outside shell: just black diffuse , reflection, full refraction, and fog color
Inside liquid: black diffuse, reflection, full refraction?

SO only outside shell fog color should give me color ?

Doesn't look like enough light, or the right shape judging by the shot but see how it looks with accurate geo I guess.

I would apply a VrayBlendMtl to it, and make loose specular reflection on the base, and a tight specular reflection on the coat material. The color looks nice, and the lighting may or may not be good, but the specular reflection is flat for a specular reflection. Blending multiple specular's should give you some more intriguing results.

I'm not sure with what I should control the color. With diffuse or fog? I can;t get the color bright and saturated enough with fog, even when cranking up lights.

I think u have to add some kind of texture to them in 1st place. Other than that its simply post and AA filter that does the trick... Everything else you already have...

[simmsimaging]

there really shouldn't be any diffuse component per se. Diffuse should be full black, refract full white, and the rest comes from fog. You might want to add some SSS type effect but I really think you can get most of what you need out of fog and refract glossiness.

Textures are only necessary in the reflection slot IMO, but if you add one to the refract slot it may give you some interesting results. At that point diffuse will become a factor though, so your diffuse colour would need to be orange/yellow and your render times will take a hit.

I still think lighting is more the issue though: as was pointed out the specs do look flat and they do not appear to be refracting much dynamic range.

Can you show what you are using for a backlight texture?

I think I've finally got it I just used simple one face model and... you know what was in this case of material is the main factor ... CAUSTIC. I cranked multiplier hard and here it is:
Also lowering refraction IOR



and after a bit of post tonal adjustment:


Regarding back light it's just vray plane light

material and caustic settings:

I think shell will be good. When You look at the photo, capsules looks there is a space inside. But in the last image with caustics, it looks there are made of a one piece of a glass. My opinion.

[simmsimaging]

much improved, but I agree that they would still look more like your reference with some thickness and an interior liquid. Still, what you have there is looking quite good

[lukx]

yeah I will play with thickness and liquid geom also.

looking good so far
