Pyro on viewport better than the render Sept. 3, 2010, 10:35 a.m.
By default, the volume filter size is quite high: 1.5. This blurs the renders.
Try to lower the filtering values, and/or change the filter type.
Parameters to add to you object are:
- Volume Filter (vm_volumefilter)
- Volume Filter Width (vm_volumefilterwidth)

you may also increase the density in the shader to match the viewport. The gl display is quite opaque, and the shadows strong.
Volume Shadow Matte / Phantom? Aug. 20, 2010, 10:12 a.m.
I had the same problem some times ago, and I got this answer from support:
“It's not possible to match the matte volume density to the density on the surface shader. The matte shader uses a default density of 50 to match the default value on the VEX Volume Cloud shader.
To use a different density for matte shading you can add the ”Matte Shader“ (vm_matteshader) property to the torus object, create a VEX Matte shader, assign the shader to the matteshader setting, then change the density on the VEX Matte shop. ”
Actually, I just added a matte option to my shader witch outputs only opacity:
Cf = 0;
Of = newOf;
Af = 0.0f;
That works in houdini10.0, and will work in 11.0. Maybe there is now a new way to do this in houdini11.0.
Cheers,
