Hi friends,

Currently I doing a shot need to render more than 200 million particle.
It's a sand effects so I just render them as point with mantra surface(diffuse only).

For optimize I've removed all the attribute I don't need.
The lighting only one sun light and one env light.
And everything is delay shader.

But the rendering will took 30+GB memory…..

Sorry I can't provide the scene, but does we have a idea can optimize more?
Any advise will appreciate!

Try to slice the sim or pack it if it's not already packed.

Hi trojan,

Thanks for the advice.
Yes, in the end I slice them. render separately and merge in comp. that's cool!

Cheers,
