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/>

Real-time Refraction Demo: Mosquito in Amber

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.

Studio V1 For Car

The ZiS-2 was a Russian 57-mm anti-tank gun used during World War II. Development started in May 1940 and in the beginning of 1941 the gun was adopted as 57-mm anti-tank gun model 1941 (ZiS-2). The velocity and mass of the armour-piercing 57 mm projectile allowed it to attain sufficient kinetic energy to penetrate up to 90 mm of armour RHA while keeping the gun sufficiently light, mobile and easy to conceal. It is a automated-action gun with vertical block breech.  The rate of fire can reach 25 rounds per minute. The carriage has coil spring suspension, which allows towing with a speed of up to 50 km/h (31 mph) on highways

Here is my new photogrammetry project. It's low poly model with 50K tris, 8K albedo and 4K normal map.

The Borchardt C-93 (Construktion 93) pistol was designed by Hugo Borchardt (1844–1921) in 1893. Ludwig Loewe & Company of Berlin, Germany, a manufacturer of machine tools, produced the C-93, a semi-automatic pistol that he had invented based upon the Maxim toggle-bolt design. Borchardt also developed the high-velocity bottlenecked 7.65×25mm Borchardt cartridge for the C-93. Borchardt's assistant at the time, Georg Luger, also claimed to have influenced its design. With over 3,000 manufactured by Loewe and Deutsche Waffen und Munitionsfabriken, Borchardt C-93 was the first mass-produced semi-automatic pistol.

**The Rayback Mohawk from Split/Second**

The Rayback Mohawk from the 2010 Arcade Racer Split/Second Velocity.

Features your typical early 2000s musclecar look and its original paintjob. Aswell as an updated Interior, rims, brakes and a new engine with animated radiator fans.

I tried to recreate the vehicleselectionscreen from the original game and i hope it takes you back to the nostalgia this game and its design had.

I hope you guys enjoy it and thank you very much for those 300 Follows here on Sketchfab have a nice day.

This is just an experiment with exporting a particle animation to Alembic format (.abc) from Blender.  I created the effect using similar steps as those shown in this tutorial (except I used a cube as the particle so it's lower poly, and I added randomness to the velocity, which I don't like in retrospect): https://youtu.be/k5WH5WY1Osc?si=Y1sfy87AwmzhI96m only up to the point where you start adding a material and adjusting render settings, since that is not necessary for export.

Initially I just selected the emitter and particle and exported them as Alembic with default export settings, and overall it worked remarkably well.  Sketchfab had no issue importing the animation.  Unfortunately though, without any adjustments, the animation's two stages (rising up into the air, then bursting) came out overlapped.  So I went looking for a way to fix that, and found a great Blender addon for baking particle effects by searching Gumroad for scaryplasmon CakeParticles.

In future tests I will remap the texture.

A 2026 "Major Glow Up" for the Aston Martin Valhalla. This specimen moves away from traditional paint into an Obsidian Wildberry Liquid-Glass finish (#1E0536), designed to manipulate light across its active-aero surfaces.

Grounded by Satin Gunmetal F1-style monoblock rims and Electric Phosphor (#00FFC8) braking units, the Valhalla functions as a high-velocity "Institutional" sensor. The internal "Safety Cell" is a sanctuary of Charcoal Alcantara and Soft Lavender (#E6E6FA) instrumentation, signaling a state of constant "System-Ready" performance.
