Particle color by age

HI


Not luck changing particles color depending their age. That’s my shading node tree and I’m using cycles
Any idea? Thanks

Particle Info node is limited to rendering of Objects or Groups instanced through a particle system.

To color a volume via particles, you need a point density texture.

Tornado in gooseberry was made through a texture developped only for this project and was never available in an official release.

But for that particular thing, you may attempt to simply use a gradient texture.
