Particle transparency and ReflectionYou can get transparency, reflection and
refraction with the new particles by plugging in raytracing nodes in the colour
input in the tree, they just take ages to render... I just hope you don't have
too many particles to render...
To use the old particle shaders you mentioned, "simply" delete the shaders from
your ptype so it inherits the shaders attached to the cloud itself (the only
place where you can attach a volume shader for particles). Now, in the clouds'
rendertree attach the appropriate particle shaders you want. Save your scene.
(can't remember if an actual XSI restart is needed at this point) Open your
scene. Draw a region and your particles are now there, rendering away with ye
old shaders... it's a convoluted way of getting the old shaders to work as they
do come in real handy some times, but I think it's got something to do with the
way generates the particle files which contain some info regarding... and then
I'm lost... lucky for those bread crumbs I thought I had left behind...

Subject: Particle transparency and Reflection
Hi, I am currently working on a job with the XSI particles in version3.5 and
found myself caught with this nasty rendering issue. I am having trouble
rendering the fluid particles to be transparent and reflective. The default
shaders for the particle cloud and the particle type doesn't have any
transparency or reflection parameters. Now, I've looked into the old "tap water
" scene from the XSInetview under the library->simulation section, and tried the
"water fall" simulation tutorial at XSIBase. It seems to me that, at least in
the old version of XSI (2.x), I can assign a new particle shader like particle
blob or particle_fluidv2 to the particles. Those shaders have access to
transparency and reflection properties. I've tried to hook those shaders and
their respective volume shader into the appropriate cloud material node in the
render tree. The results did not show up in the render. So I am asking if
anyone have had success and know how to render transparent liquid with the XSI3
.5 fluid particles or know any alternatives. Thanks in advance.
