Can I use something similar to the ParticleInfo Node but for meta objects?

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

1. My example Material
2. Sphere as dupli object
3. Metaball as dupli object

• Metaball doesn't have age. If the metaball is dupli of particle you could do the same as with cube particles. This question is very unclear for me, can you specify? What info for metaballs would you like to get exactly? Commented Apr 29, 2015 at 15:19

• I see your problem now. This is because all the metaballs are treated as a single object:( Thats sadly how they work - they merge into single object. Maybe you could color this with a gradient from top to down as a workaround? Something like this could work work you: blender.stackexchange.com/questions/5422/… Commented Apr 29, 2015 at 16:41
• So, am i right when i assume that there is no solution for my problem? Commented Apr 29, 2015 at 17:19
• dont know how long you didn't check your Stackexchange but I posted the solution. I dont know if Pointdensity was a thing in 2015 but now you can do it Commented Nov 16, 2017 at 9:56
