View Full Version : Animation, very slow feedback

Hi all!

We are experiencing some very strange slow feedback in viewports. We are working on fast machines but still only get like maybe 1/2 fps while working on maybe 1000 or less polygons visible in the viewport.

When working on other projects, the feedback seem normal so thats why I think there must be something wrong with the setup.

Basically, there is 3 versions of the sames characters, one very low res, which work quite well, but as soon as you go with the medium res version to do facial animation or lipsynch, it is impossible to get any feedback in real time, so you have to make playblast all the time which is very time cunsuming.

Even when hiding everything but the character itself, it seems to have very little influence on the real time playback so that is why I'm thinking the problem much come from something else, maybe some setup mistake???
(We have a very good tech support here, it is so strange that they never get around to find the problem..)

Anyway I'm not very good at technical stuff in Maya so please If you have any suggestions or things to try, please let me know.

Thank you very much!

What display card are you using?

history...history history!

select all the objects that haven't been skinned or constrained to anything and select 'edit - delete by type - history', after deleting it make sure nothing has gone wrong in your scene.

history is a pain and needs to be deleted at least every hour imo. if this isn't the problem, I don't know :s

gforce4 ti 4200

pentium 4 2.6GHz

1 Gig of RAM

but it's not related to the computer speed, it's not a too much polygons in the scene problem.
(I remember working on heavier characters 5 years ago on crappy machines and still have better real time feedbacks)

Doesn't really matter if I hide all the character clothes, hair... or if I only have the head mesh. I see very little difference so that's why it must be a setup problem..

Thanks

Robken is most likely correct about the cause of your lag. good ol' CPU processing is required for animation. Maya has allot to do if there are like 10 poly splits, 2 subdivides, a polysmooth, and a skinCluster to calculate anytime that the geometry deforms. Put your rig in a bind pose and delete history on everything. Then rebind. Your rig should run well, maybe not RT but well.
