When I recreated a scene, I used emit per second, not total number of particles. It doesn't happen then. Indeed there seems to be a problem with the slide on surface node, when using a total number of particles AND the emitter is inside the grid. No idea what it is, but at least I can confirm it.
As a workaround maybe just using emit per second and animate the value to zero after emission? sven From: [email protected] [mailto:[email protected]] On Behalf Of Chris Marshall Sent: Friday, June 24, 2016 5:43 PM To: [email protected] Subject: Re: ICE and Mental Ray - seen anything like this? It's probably just my system. I haven't got time to reinstall Soft so I'll set a test render going over the weekend and see how it goes.

It's something to do with the Slide on Surface compound. I've managed to recreate the bug in a new scene. Something like this, if you're having a slow Friday afternoon, like most of us here in the UK!:- Create and empty point cloud and emit some particles from geometry ie cube (dont move the cube). Create a grid (don't move that either) and use that as the surface for a Slide on Surface compound for the particle emission. Put a Simulate Particles node at the end of course. Step on to frame 2. The render glitch happens when the emission object cuts through the grid, which in this scenario it does, and you make the Offset Distance in the Slide on Surface compound, anything but 0. Draw a render region. That's it. Chris On 24 June 2016 at 14:51, Rob Chapman <[email protected]> wrote: Wow, plotting particle cache and rendering that?

Another thing might be switching from "Use from disk…"to "Load in Memory…" in the clip property of the textures. (unlikely though but I've seen buckets rendered differently across machines when it was not set to "Load in memory") sven From: [email protected] [mailto:[email protected]] On Behalf Of Chris Marshall Sent: Friday, June 24, 2016 1:25 PM To: [email protected] Subject: ICE and Mental Ray - seen anything like this? Hi All, I have a very weird render glitch. OK I know I'm still using Mental Ray but I'd need to fork out a few thousand to get Arnold running here. So I suddenly have an issue rendering a point cloud, image attached. Anyone seen anything like this before? I might need to rebuild it from scratch to see where the problem is.
