Xparticles particle fade out

Hello,

since it is not possible to use the xparticles material in octane, how is it possible to achieve that the particles fade out over time? So they change their transparency?

Thanks for any thoughts and hints :)

I've just tried to use an animated texture (with the fade in - fade out), but sadly, all instances of the emitted particles fade out at the same time, so this (cheap) workaround doesn't work.

If it's small particles like sparks, I'll use xpGenerate to make mesh spheres, then use xpScale to make them shrink before killing them. It's a fudge but it looks convincing.

I think Octane simply doesn't have pro level particle rendering yet.

Thanks! Unfortunately, they're a bit bigger, but I guess, that's the way I have to go.

Hi just found this thread and wondered if there's a better solution for 2021?

Thanks!

Hi,
from some time, we have the Octane Instance Color node:
https://docs.otoy.com/cinema4d/InstanceColor.html

You need to change the mode from File to Particles, and drag and drop the XP-Emitter in the proper field.
Then you can choose between different modes, for example Age, set the gradient from White to Black, and connect it to the Opacity channel of the particles material:

And you can use the Gamma, or modify the Gradient, to fine tune the effect.
