I am looking to create a ‘silicon / resin’ material that will look like the linked image.
So the aim is to picture the ‘thickness of the resin/silicon’ while being transparent. In addition, add some bubbles with some noises ?)
I assumed I had to tweek around the refraction fog but I can’t quite achieve that.
As I am working on Rhino, I am also wondering if it should be applied to a closed polysurface (kind of a volume thing) or single surfaces on the outside.
As long as it’s a closed mesh then tweaking the fog params will work just fine for this. Blur the refraction/refl a bit.
You’ll need caustics to get it looking right though.
Bubbles…just scatter some throughout the mesh, with a clear glass mat.
Will be interesting to see the results
Why did you set bias to 20?
I would start with a phisically correct material, and only then tweek the values artistically.
resin ior is maybe between 1.45 and 1.52, looking at the reference i would put between 0.85 nd 0.95 on the glossiness both fr reflection and for refraction.
I would add a little bit of chamfer to the corners.
And last thing make sure that the resin base planar geometry is not coplanar with the wood…I would make a negative push of 0.001 cm.
This is what I worked up with a mix of stuff. I added a composite which includes edgetex and a random smudge/grunge map, which turned out to be crucial to add much variation.
Looks pretty similar to me but I’d have to have all the necessary extra geometry - the boats etc. in order to develop it further…I’ll leave that bit for you
Lighting is just a sun, caustics on with max 300 photons. Make sure your sun’s photon radius is large enough - what could be causing those black parts.
Hdr in the env reflect slot.
I would consider tesselating the mesh and adding a subtle noise modifier to it as well so that no face is totally flat.
Lighting a completely flat reflective face is its own challenge (involving gradient light sources to get a variable tonal gradation, aka “whispy-doo.”). A slightly uneven surface will provide much more interest in any reflection or refraction as well.
fixeighted’s example is definitely in the right direction.
Don’t be afraid to alter the surface of the non-resin material underneath to get it darker in the middle, etc. Use this surface under the resin to help get the look you are after.
