Particle Transp Mapper is a utility node used for certain
cases when you are rendering particles using Software Rendering.
Normally, when you do Software rendering, you control the particle
transparency using the Transparency attribute of the Particle Cloud node. When
you do Hardware rendering, you control the particle transparency using
the attributes in the Particle Shape node. The Particle Shape node
allows you to do many things; You
can add per-particle attributes, with special expressions to
set the transparency. These values are all used automatically by the
Hardware renderer, but not by the Software renderer. The Particle
Transp Mapper node allows you to use all these attributes in the Software
renderer as well as the Hardware renderer.
To use this node: Create a Particle Transp Mapper node. Connect
its Particle Transparency attribute to the Transparency attribute of the
Particle Cloud object associated with the particles you are rendering.
Now when you do Software rendering, particles
will get their transparency from the attributes in the particle shape, just
like they would if you were doing a Hardware render.
Note: There are differences in result between using hardware
rendering and software rendering. In hardware rendering, for example,
transparency is treated as though the particles were in a separated,
non-overlapping layer, but in software rendering they are treated
as volumes, with overlapping allowed.
Note: This node is obsolete, and used for backward compatiblity only
The functionality is now provided by the particleSamplerInfo node.
