Messing around with refractive materials!

The [Mosquito scan](https://skfb.ly/6tFKT) (415k tris) is from [Geoffrey Marchal](https://sketchfab.com/geoffreymarchal).

**Modeling**:

* The scan was first remeshed with [mmgs](mmgtools.org) and baked to a lighter version (11k tris). 
* The amber fragment was roughly sculpted in blender ("I have no clue what I'm doing" style), keeping the main face flat (clay strips + flatten brushes).
* The small fragments inside the amber were done by splitting all the main fragment edges and applying the "shrink/fatten" tool, followed by a random Displace modifier. Exterior fragments were then removed with a boolean modifier.

**Material**:

The important parts are the roughness and normal maps, which are a mix of PBR textures (rougher edges, smoother main face), while the refractivity is just a product of tweaking Sketchfab settings: opacity set to refractive and using the object's roughness.

Refraction is the phenomenon that makes light bend when passing through different transparent materials due to the velocity of light changing in different media. It makes objects behind the refractive material look distorted. Refraction is useful for simulating glass, gemstones, and many other transparent materials. Real-time refraction is available on all plans, including Basic - [learn how to use it on our Help Center](https://support.fab.com/s/article/Transparency-Opacity).<br/>

Refraction is the phenomenon that makes light bend when passing through different transparent materials due to the velocity of light changing in different media. It makes objects behind the refractive material look distorted. Refraction is useful for simulating glass, water, gemstones, and many other transparent materials.

To see for yourself how refraction works, just rotate the model, paying attention to how the shell appears to distort beneath the egg white.

Refraction Demo: S**t happens

As it appears to be a trend, a small WIP diorama ([Nice one here!](https://skfb.ly/6xvV6)) just to try out some lighting technique for an incoming model (not a WIP I hope).

The refractive "box" around the model is just eye-candy, what was really of interest to me was to get an idea about bubbles (spheres with an emissive material coupled with dithering transparency), sun rays (elongated planes with blending opacity and a light emission to them) and the ground lights (not done well here, but basically voronoi textures to simulate the effect of waves on the light, baked on the ground model).

The ground is a quick and ugly dyntopo sculpt done in blender, while the little fish are just a particle system set with a lowpoly mesh as render object.

A nice point to spend time on will be the ocean surface, to do with the appropriate modifier in blender, and a refractive/small-scale-roughness/foamy-at-the-edges material.

Plus, I should try to animate rays, bubbles and fish (as boids) to give it a living touch.

Built with refractive transparency and high roughness, so if you are trying to achieve similar results, use those and water as a hdr.

Water Orb

A high-quality, game-ready hero prop of a vintage kerosene lantern. Modeled and textured in Blender with a focus on realistic PBR materials.

Key Features:

Materials: Galvanized Steel body with realistic refractive dirty glass.
Workflow: High-to-Low poly workflow with baked normal maps.
Optimization: Optimized topology (~12k tris) suitable for first-person games or high-quality environment scenes.
Render: Real-time PBR rendering.

Created as a study in hard-surface modeling and texturing.

Galvanized Steel Kerosene Lantern (Game Ready)

A detailed incandescent light bulb that can be used to decorate your scenes. The filament can be used as an emitter; there will be no fireflies, because the glass-material is non-refractive.
And don't worry, it's modeled to real-life scale! Check out its low-poly counterpart here: [Low Poly](https://sketchfab.com/3d-models/low-poly-light-bulb-a7d27c2224d94c86a04083de8f9df7db)

Incandescent Light Bulb

Like a ruby, our Rosé cuvée is forged by the Love and Passion of excellence.

A natural ruby of 0.45 carats is inserted on the central label. Corundum, red, pear. Refractive index : 1.760 - 1.770 Biref 0.010 Specific Gravity : 4.00

Tasting : Bright light pink colour and vivid small bubbles. Pure and floral nose with rose petal, fresh red berries, ripe citrus and some roasted nutty notes. Good grip on the palate, youthful fruit with some mature autolytic notes, brioche and butter with crushed raspberry, red citrus, a creamy texture with bright acidity and a long grippy finish. Attractive, generous and vinous.

Vignification : traditional Champagne pressing. Settling and racking by natural gravity. Alcoholic fermentation between 16 and 20°. Maturing on lees, partial malolactic fermentation. Vinification of the red wine in open vats, grapes destemmed, manual pigeage.

Grape variety : 95% Chardonnay 5% Pinot noir Dosage : 8 g/l Abv : 12,5%
