While using Fire in either Rhino or Maxwell Studio the object being rendered jumps and wobbles all over the viewport and ends up looking like the attached image when the render is finished. Has anyone else experienced this or this caused by a poor job of setting things up on my part?

This is the resulting Fire image of a ruby in an odd looking setting:

It looks like there is just very heavy depth of field blurring at the object's distance. If you are expecting the object to be in focus, you would want to check that you're modeling at the correct scale. As you are apparently rendering jewelry, it is probably just that the correct scale is actually very small, and you simply need to set up your camera's fStop and focal distance appropriately.

It's much stranger than a focus problem JD. The object being rendered jumps all over the place while it's being rendered and then ends the rendering session of Fire as you see it. If I leave the drawing being rendered, go to another drawing and then come back it works quite well as long as I don't try to change my view point or move the object while it's being rendered. If I do either of those things it starts jumping around again. I'm going to try it on a different computer this evening and see if I have a problem on that one as well. Thanks for your response by the way!

Is it possible that you've enabled motion blur for the object? That would also give this impression when rendering in Maxwell Fire. You can quickly find objects which have motion blur enabled using the commands Maxwell_SelectLinearBlurEnabledObjects and Maxwell_SelectRotationalBlurEnabledObjects.

Yep, that did it. Thanks for the help JD.
