any idea of what might cause this? Only happening in the site file that I'm working on, other files which are much larger working fine.

Not really -- what is the CPU doing when it appears to have stalled? The first thing I'd check is that there isn't some piece of geometry way out in space.

[Josephus Holt]

it looks like at least one core is active during what appears to be a stall...I waited for about 10 mins or so. I did a "select all" and then "zoom to selected" and found nothing out in space.

Anything else I could look for? Might be possibly connected to the blocks as I've never had this problem before. I'll go through the block manager and clean that up, save and try again.

I found the problem...it was a bad mxm.

[JDHill]

That's interesting, do you know what was 'bad' about it?

[Josephus Holt]

I do. It had a displacement layer in it. When I was adjusting the amount of displacement at one point the render inside the maxwell editor was taking so long...it looked like it was going to take hours to get to SL7, and I had to get a render going, so I terminated the app in the windows task manager, but apparently left the mxm in a "bad" way. That brings me to a question, I've had that happen a couple of times editing the displacement setting and the render engine taking much more time than I have for it to do that, is there any way to safely terminate that render...I don't see any cancel or abort options.

If a preview is rendering in the plugin's material editor, you can cancel it by double-clicking on the preview image, or clicking the small 'refresh preview' button.
