Different mesh settings for particles from different groups

[Whatsinaname]

Is there a way to apply different settings for particles coming from different groups during the meshing phase?

 

An Example:

 

I've got a particle system, consisting of three groups: Starters, Leaders, Trails.

 

Now, I do not want to see any of the particles in Starters, want those in Leaders to be meshed with a slightly larger radius and the ones in Trails with a smaller radius.

 

In order to mesh the particles, I basically use a VDBfromparticles SOP, filter those using VDBReshapeSDF and VDBSmoothSDF and then use a convertVDB in order to create polygons.I know I can maks certain areas of the mesh but it was way more convenient if I somehow could grab the group the particles are in.

Doesn't it obey the pscale attribute? If not, you can also try using VDB From Particle Fluid.

Append an AttribWrangle or PointWrangle before VDBfromparticles or VDBFromParticleFluid to vary pscale on groups.

 

Then use this code:

if(inpointgroup(0, "leaders", @ptnum))
    @pscale = 0.05; // set pscale value


if(inpointgroup(0, "trail", @ptnum)) //use your own group
    @pscale = 0.02;


// and so on.........


else
    @pscale *= 1;

Replace leaders and trail by your groups.

And change pscale value whatever works for you.

 

And if you have more group just keep on adding lines.
