reading the PC manual/tutorial it gives the impression that the PC vol tracer can be placed on any object and will affect all PC settings "encompased by that object"

I can't really see what they are getting at here..the vol shader seems to ONLY work on an enviroment object

With that said suppose i want 2 vol shaders with 2 setings say crispy for vol 1 and world step size of 30 for vol 2. The idea is to have some particles render accurately but slowly and other bigger particles to render fast

As i seem to only be able to put the vol shader on an enviroment how do i create 2 sep enviro effects ?

I have tried creating 2 nulls and dropping the 2 enviro objects and their asociated emitters inside them but there is no seperation of effects

I have tried 2 stage obkects with each set to a different enviro object but again no effect

Does anyone know how to achieve this and also what they mean by assigning a vol tracer to any object apart from an enviro object ?

Works fine here.

Try this file and see if it renders (R9 format) http://w1.695.telia.com/~u69502813/stuff/separate%20tracers.c4d

I thank you

Ah.... so using nulls was my mistake you have use cubes and i note the effect is now conatined within the shape which is new to me and opens up all sorts of possibilities

So to have say clouds and sparks on the ground render with different enviro settings i would have to create an object to "hold" the clouds and thier vol shader

Another thing R9 file opens up fine in 8.5 ...which is nice :-)

- Yep. One can assume that the volumetracer simply restricts itself to the bounding box of the object it is assigned to. Nulls don't have much of a bounding box in that sense....

- It's quite an interesting twist. I have actually never tried this myself before, but I read the very same section in the manual a while ago and thought "hmm... that could be useful...." :D

- Ah, good to know.

... ... I'm pretty sure that Amnesty International will step in here any day now with some serious remarks on how Meg and Otto are generally treated. Human Rights Watch are already scared shitless :D

She loves it..she's that kind of girl you know.


This is great..you can fill a scene with particles (that don't effect render times untill needed) and have your objects/abused megs move through them

This may be handy for the meteor impact scene i never finished. Could never get a good effect of a fire storm raging across the planet after the impact..the pyro was either too big or too small


Now i may try this effect to get the particles to shade the surface of the planet as they do a move on surface..may work

Well bounding box woldn't be accurate either, or meg would simly look like a cube of fire. It uses the volume of the mesh itself

Well, that's even better - and quite surprisingly nifty even! Opens up a lot of possibilities for Meg :D
