Particle data in Octane Material Override?

[vantrum]

My goal is to utilize particle attributes in my Octane material override - but I'm getting stuck. How would I approach using, say, the age of a particle to determine the opacity of the material? Or to change the color of the material as the particle ages? Thanks for the help!

I don't think you could use attributes such as the Particle Age to drive an input to an Octane Override - since the Octane Override is for a "Material", and all particles of a given replicators would use the same Material.

Hey Paul,

this seems to work in the C4D Plugin (https://docs.otoy.com/Cinema4DH/C4DPlug ... eColor.htm). This would be really useful to have in modo.

Btw. MotionBlur for Replicators would be great too. Maybe i'm doing something wrong, but i can't get it to work. In the Demoforum you said this is going to be implemented (viewtopic.php?f=25&t=56680&p=345898#p345898). Is there a way to get particles with motionblur?

(also Replicators don't update when scrubbing the timeline. Is it possible to change this?)

Thanks in Advance!

Have you tried turning on the Render Cache? It may already support this.

Yes, i tried that, but there is no difference

Can you send me a simple scene LXO which shows this problem and I will take a closer look.

Might it be possible to store Particle data in a vertexmap to control color of the particles in Octane?

I don't know. Someone with deeper Modo knowledge would need to answer this one.

If the Particle Simulation is fed into a mergemesh Node there are some vertexmaps shown. Do you have any idea how to use them?

I'm sorry, I don't know the answer to this.
