Hi everyone

I'm am trying to render a graphically simple animation of a character on a white floor but when I switch on motion blur (either 2d or 3d) part of the floor disappears when rendering. I am using software render in Maya 8.0. Hellp! :-s

Thanks in advance!

Any chance you could post a Pic?

I assume you've not accidentally put it on a sepperate reander layer?

Hi again,

Here is a render with motion blur, the creamy coloured floor should extend to the bottom of the frame, instead as you can see it splits in half revealing that black cylinder underneath which appears later.

Any ideas on how to stop this? This definitely has something to do with motion blur as this doesn't happen when I turn it off.

All the best
Simon

Aint a clue mate, maybe render it in layers so that the floors sepprate from the figure??

that would be my work around for it.

sorry for the late reply.

it's your camera clipping plane i think. Adjust it by selecting the camera and then opening the attribute editor and adjust the near clipping plane to a smaller value

Tried that but still no joy, I just managed to solve it by deleting the poly plane floor and replacing it with a nurbs plane. Still no idea why it happened though :-(

I've seen this before. Fun Maya bug (it's been around forever). My guess is that your ground plane is a giant plane object with just 2 triangles (or one quad that gets triangulated at render time). Try increasing the tesselation of your ground plane to 20x20 or something like that. That should fix the problem.
