Hi,
Since upgrading to MtoA 3.0.0.x, using nParticle instancers causes maya (2018) to freeze for a while. My test scene contains an nParticle emitter and an instancer whose input geometry is a default polyCylinder.
Lowering render threads doens't help and the render log in debug mode shows more than 90% waiting time.
Anyway to fix this issue ?
Thanks in advance.

Hi
I had the same problem in Maya (on Mac). Any scene with instances (nParticle or MASH) simply would not render, or Maya would crash. This started happening when we updated to MTOA 3.0.0.2.
I just reverted to MTOA 3.0.0.0 and it fixed the problem.
Good luck
I want to add my experience. I think it's the same complex.
I also have a problem with the Instancer but fed by a MASH system. It's ~75000pts, 9 simple MASH networks/Instancers and very simple geo. It takes at least 40min, hammering 1 cpu - I stopped it here - before the actual rendering may start.
Until now I only did some simple tests with one MASH system and 40000pts to reproduce the issue. At least it produced very inconsistent times for the Arnold "node init", though it never took that long as 40min.
I did yet not try the downgrade. I am on MtoA 3.0.0.2 on Win7x64SP1.
Hello, could any of you try with latest MtoA 3.0.1 ?
On our side we could reproduce the problem in the attached scene in (BSPR-31260) for both MtoA 3.0.0 and 3.0.0.2, but it should be solved in 3.0.1.
Please let me know if it really solves it for everyone. And thanks for reporting.
Cheers,

Great, I updated to MtoA 3.0.1 and it fixed the instancing / freezing problem. Works flawlessly.
