Hey everyone
does anyone know how to render particles as anything other than the default? F.e as disks or volume spheres in Solaris?
In the regular rop context this is easy. You can simply change exactly this in the Arnold render properties tab on the geo container.
In solaris you have to use the "rendergeometrysettings" node as far as I know, and here this option is somehow missing.

In solaris I only see the option to change how curves are displayed. The tab for particles somehow just isn't there.

If anyone knows any tricks please let me know

With a Render Geometry Settings LOP under "Geometry" you can set "Render points as" to either Discs or Oriented Discs.
Not sure about rendering them as volumes though.

The solution is to manually set it to spheres using vex:
Also there is a potential issue with solaris, material should be always at the same level as the geometry point...solaris is a house of cards....

usd_setprimvar(0, "/sopimport1/points_0", "primvars:arnold:mode", "sphere");
usd_setprimvar(0, "/sopimport1/points_0", "primvars:arnold:step_size", 0.00001);
usd_setprimvar(0, "/sopimport1/points_0", "primvars:arnold:radius", 0.1);
usd_setprimvar(0, "/sopimport1/points_0", "density", 1);

WHY do we need to use "primvars" can't it be just @ like the rest of Houdini.......*pulls hair*
WHY Arnold is so poorly integrated with solaris....*pulls more hair"
