Hi Adrian,

> render bigger/wider then crop down after motion blur processing?

I think I remember from reading in either the release notes or
the docs that XSI now has controls to help do that, keep the
aspectratio and camerasettings as is (no shifts in POV) but allow
to render additional sourounding pixels, like taking out the cache
and rendering "open gate" in real world.

You know where that setting is?

Or how would you reset the camera to keep the framing but get
extra pixels usually?

Cheers

tim

P.S: I´ve just installed the demo, even the rsmb standard looks great...
(exept for the  red cross and imprint but that´s o.k. for testing it...)

 The biggest one for me is when lots of objects are whizzing past the camera at high 
speed - it has trouble dealing with objects that have just gone (or are going) out of 
shot. Then again if the pixels simply aren't there to process whatchya gonna do? :)

 Hi Lee,

 thanks for the link to revisionFX, I had thought ReelSmart MotionBlur
 to be a lot pricier. Admittedly, I don´t even have the $150 for the
 pro version (personally would go for the AE version) currently but
 that´s a matter of time...am about to upgrade to the Adobe Production
 suite and will probably just add the plug-in to that shellout then soon.

 Can you give examples where reelsmartmotionblur didn´t work?

 Pierre Jasmin of revisionFX is an active member of the highend3D maya
 listserver, usually really responsive and open to looking at anything that
 may break or stress "his baby". I´d forward it, as I´ll try to buddy him for
 a student acount anyway - he´s probably nothing to do with sales, thought.
 (May as well result in my email being put in his spamfilter. lol.)

 Cheers

 tim

 I've found for most jobs ReelSmart Motion blur does a pretty good job -
 Also afford you the luxury of being able to tweak the blur amount in post.
 It's all done via the FXtree which is nice.

 help with motionblur optimizations - alternatives?






 ---I´m sorry if you get this twice, I had used a wrong
 email adress to submit, got a bounce reply, not sure it
 showed up anyway ----------------------------------

 Hi guys,

 I´m running into problems in tuning the speed of
 motionblur calculations. I suspect I do something wrong.

 I have a scene, 650 000 tris, xsi_ambientocclusion
 piped into the ambient slot plus one pretty large and
 highly sampled arealight. Renders at roughly 1min10
 with reasonable AA (Box -1/2, 0,075 threshhold).
 (768x432px)

 If I activate motionblur, shutter close at 0,5 and set
 Evaluate SRT for entire frame, Deformationblur to on,
 treshhold to 0,1 and keep the steps at 1, I get a rough
 12min per frame. Quality is decent, no problems with that.

 Unfortunately, I won´t be able to use 3D motionblur with
 such a speedpenalty, because I can´t throw more machines
 at it to speed up turnaround but would have to bring pass
 time down to max. 3min/frame or 10min for all (~5) passes.
 I simply don´t have the time+budget to up any of that.

 So, I´m desperately looking for alternatives, any tips
 you´d bewilling to share? Stuff I could read up on?

 Cheers

 tim
