In cycles you can control the color of a Particle-(dupli)Object with the ParticleInfo Node. You can, for example, divide Particle Age by Lifetime and use the result as factor for a mix shader.
I wonder if and how it is possible to do the same with a metaball (instead of a cube)?
I have a particle system and i'm using a object (in this case a sphere) as dupli object.
In the picture you can see that the material color is affected by the age of the particle. If i change the dupli object from the sphere to a meatball the age of the particle has no influence. The material is same material that i used for the sphere
- My example Material
- Sphere as dupli object
- Metaball as dupli object
