THANKS in advance!
I am testing the scene with two particle mixing colors using the magma flow and I want range of the gradation to be narrow.
I’ve been playing with the meshing section for the frost but I just can’t get the result.
If I put low value in blend Radius Scale it sure takes away the gradation of the mixing color but shows the vertex shape.
Some thing can be done in magma flow? I am lost here…
I hope someone will reply…
Can you provide a screenshot of your MagmaFlow nodes? If you provide a test scene that’d be even better since we could use the same flow.
Screenshots of the actual meshed result might be useful too to illustrate the problem. If you can throw in some Photoshop hand drawing of what you expect to see, it would be a bonus 
Keep in mind that Frost will take the influence of the nearest particles to propagate the channels to the mesh vertices, but if your Magma is on the particles, you have very little control over what each vertex will receive. On the other hand, if the Magma was on the mesh itself (the Genome modifier, which is part of Stoke MX now), then you could sample the nearest particles and control the influence on each vertex. Unfortunately, Stoke does not have a free mode, but we could give you an evaluation license to give it a try if everything else fails…
