The RifPlugin presented here is intended for use with Maya's Particles and nParticles
when their "Particle Render Type" has been set to either Points, MultiPoint, Streak or
MultiStreak. In the "Shading" panel of the particle shape tab the minimum size of
the particles "Line Width" or "Point Size" is 1. Often this value is too large.
A work-around suggested on Pixar's RenderMan forum is,
RtVoid Particles::points(...) RtVoid Particles::curves(...)
to override the value of the points and curves "constantwidth" parameter.
Step 1 - Compile the Rif plugin
Refer to the tutorial "Cutter: C++ RifPlugins" for information about setting up and using Cutter to compile, link and build plugins.
Step 2 - Using the Rif plugin
Go to the Render Settings Advanced tab and browse for the compiled plugin. On Windows the plugin will be named "Particles.dll". On Linux and OSX it's name will be Particles.so. Set the size you wish to render the particles or streaks in the "Rif Args" text field.
Step 3 - Render and Adjust
Render your particle system. With the "it" (Image Tool) window next to
Maya's Render Setting window finding the preferred width of the particles
is simply a matter of changing the value in the "Rif Args" field and then
pressing the "R" key in the "it" window.
