Hi all,

I have an issue with rendering multiple pyro simulations at once in redshift. The first simulation renders fine, until the next one begins (20 frames later) at which point the first vanishes. I can see both in the viewport, its only in the redshift renderview this happens. If I disable the second pyro sim, the first one renders fine all the way through.

At the moment I have four simulations all beginning one after the other, with the cached sims merged in a single geo node, and all using the same material. I have tried putting each sim in individual geo nodes, and also tried creating separate but identical materials for each sim, but no success.

I'm sure this is the result of an optimisation tickbox somewhere in the redshift ROP, but as of yet I haven't found it.

Any help appreciated.

Thanks
