Maxwell Render | Official public forum

I've been playing with nParticles as Maxwell volumetrics and have been getting interesting results. (I keep thinking they'd make for good tree canopies and foliage at a distance)

Every so often my computer with 16 gig of RAM crashes when using nParticle-based volumetrics.

Is this a RAM issue? And what settings are most taxing on resources? I assume the number of particles and size and density of them don't matter as much as the sheer number of voxels called for in a given scenario. Is this correct?

Does Maya crash when you export the scene, or does Maxwell crash when you render it (the standalone application, not FIRE)?

Maxwell claims it's already running when it is not, and it asks me if I want to stop it or continue, and regardless of my answer the plugin crashes but Maya does not.

If I recall correctly.

So neither Maya on export nor Maxwell standalone nor FIRE.

Maxwell plugin launched from Maya.

Wait, how can the plug-in crash without crashing Maya? When you render from Maya, the plug-in exports an MXS file and starts Maxwell standalone (a separate process). So is it Maxwell (the renderer UI) which crashes when you hit stop render?
