I am using proximal shader to color the metaball organic structures in attached file.
Unfortunately when i clone the metaballs using Cloner, the proximal shader doesn't work properly.
How to make proximal shader working in that case?

Maybe there's another better way to set material of metaballs? I just want the particles to have different colors and blend between them just like in the attached file.

don't think so, the Proximal works with the actual placement of the referenced objects and the clones are not the referenced objects.... I think you'd have to make the metaball editable and bake the texture prior to cloning

Hi Brian.

Can't bake the objects because they will have a vibrate tag on too.
I am thinking about a different approach. I could make a second cloner without metaball and place the objects into proximal shader but there's a small problem.

There's something weird with fix clone option under cloner object.
I have a small xpresso to drive null position. I use cloner to distribute spheres and i need to have 'Fix Clone' option Off.
When i turn on 'Fix Clone' the script works fine but otherwise not.

Any idea why it's not working or how to make this work?

I have one more idea- to make Radial Cloner to drive proximal shader but vibrate tag doesn't work on the distributed objects..

your vibrate tag is going to vibrate all the clones together because the same object and vibrate tag are being cloned so they will all share exactly the same motion (it would be more obvious if you have more clones to make the helix) - I'm assuming you will want a random jiggling for each clone rather than them all moving together . If so, remove the vibrate tag and use a Random Effector on the Cloner set the Random Mode to Noise or Turbulence. If the individual parts of the molecules are going to vibrate as well the vibrate tags would work on each part...

The xpresso isn't going to work that way I think, the best way seems to be using object mode with the cloner then attach the clones to a helix spline - don't know it the geometry's right for your purposes - but that way the xpresso works.

back to the original colouring problem - one way to do it would be put lights inside the metaball sources and use a Backlight shader to color the metaball - that will clone properly (though some tweaking would be required to get the look right)
