Official release

Date – 23 September, 2020

Download – Build 4.30.00

With Phoenix FD 4.30 we added support for V-Ray 5 for Maya.

We also added force tuning to Voxel and Particle Tuners. This allows forces to affect particles or voxels with certain channels, inside or outside geometries, or according to textures, effectively allowing you to mask forces and gain precise control over how, when and where forces affect the simulation.

Rendering of fire/smoke with the Use Probabilistic Shading option is now much faster with V-Ray 5. Both fire/smoke simulations, as well as large FLIP liquid simulations are also sped up.

We did some more changes to simulations, allowing for more control and quicker iterations, and we also improved our Standalone Preview and Cache Converter tools, so be sure to check them out!
