Example: Color Source


In the following examples, a [VRayMtl ](https://docs-chaos.atlassian.net/wiki/spaces/VMAX/pages/113586760)with a [VRayParticleTex ](https://docs-chaos.atlassian.net/wiki/spaces/VMAX/pages/113575840)assigned as the Diffuse map was applied to the Metaballs object.

## **Notes**

- A [V-Ray Particle Texture](https://docs-chaos.atlassian.net/wiki/spaces/VMAX/pages/113575840) can be used in any map slot of the V-Ray Material applied to a V-Ray Metaball surface. Its blended color relates to the color set in the original particles.
