Ok a real odd issue here.... I have Maya 8, and I am currently rendering a pipe which has a sculpt deformer running up its interior to bulge it out...
Now the deformer runs into the pipe and out the other end so that nothing is left behind...
When I render using software or Mental Ray without motion blur the deformation is fine... when I add any motion blur of any kind 2D or 3D the deformer stops working just before the ends of the pipe leaving a deformed lump in the tube... which is naturally very irritating as I need a nice blur shake as the lump rumbles through the tube...
Has anyone seen this before? Is there something I can do about it (other than do a cruddy 2D blur in After Effects or Shake)?
All help appreciated in advance.... as this is the second all nighter I'm pulling to get this job done and Maya just seems to stick a bug in my way at every turn...
Joojaa, thanks again... You're like the Lone Ranger of the Maya boards
I had the shutter delay at 0.1 and the shutter at 0.9... I don't know if that makes that much difference but if you suggest checking it I will
I don't actually know how to bake deformations on to a surface (there should be a noob smiley here ), but I'm sure a swift trawl through the Maya Help will clear that up...
So once again thanks for sending me in the right direction...
BTW returning to the shutter settings and motion blur in general, is there any known values that generally "do the trick" and produce a nice smooth (and above all not grainy) motion blur?
Hi! You're only half on the right path! For obejects that are deforming, you should use Exact algorithm in the Render Settings ->MR-> Motion blur ->Calculation tab.You should be aware that lowering you time contrast could obtain less graininess and keep your shutter angle at 144.You shoud modify this only if you have nice motion blur and want a more dramatic effect.The default setting of 144 is pretty good and is by default recomended.Keep in mind to use Linear calculation for translation, rotations etc..and Exact for deformations.I highly recomand you the Gnomon Dvd's for MR and of course the documentation.Lots of people are complaining abouth issues that can be solved in 2 min just looking at the help file for render settings in MR.Cheers!
Usually the base settings are way too low so increasing contrast dont help unless you aso turn more samples to take. The contrast is there to adjust the adaptation level used for this.
