Each starcluster is FBX model with attributes. You can variate stars using color ramps included in this pack.
These models are a result of heavy computer simulation.
Features:
Realistic (Physically simulated) arrangement of stars.
Each model type has it own variations + you can variate models using color ramps.
Fully volumetric effect. You can fly through these nebulae without any artifacts.
Easy to use. It is as easy as drug and drop model and assign material instance. Then just play around with material parameters.
You can use these models for VR experiences.
