big eror with motion blur

[rezaansari]

Hi
I'm working on moving a car in the desert.
When enable motion blur (transform vertex), strange thing happens
Wheels are moved from the original place. I tested a few scenes.
this problem just happened in render final (picture viwer)

The next problem is that for motion blur for wheels, must start from the first frame to be rendered.
Cache also got , but not resolved. If I render the middle of the frame motion Blur does not work.

I thank you for helping me

First test it on C4D renderer. Test it without motionblur on Octane render. And just use transform motion blur.
If still have error send me your scene.

thank aoktar

Why c4d render?
all test done
It does not happen without motionblur
with just use transform motion blur is happens (with octane objecttag)

just use transform motion blur

The main problem is that it is sometimes right and sometimes wrong does it work?

[rezaansari]

new test
with just use transform motion blur is happens (with octane objecttag)
but
Without "octane objecttag" is Worked correctly and not Difference with Previous state

Motion blur preparation is a complex process in plugin. So my advices is to get some ideas about your problem. It's not possible quiet be sure without testing your scene. Propably it's about progressing the objects which are under dynamic calculation.

Dynamic for car is mandatory.
I hope this possibility will be provided in next versions.

Perhaps if you bake the dynamic calculations?

no.i got bake all but not Worked correctly

Just to be sure baking an animation it's not the same as caching it, baking means you get keyframes, if you do it this way I'm 100% sure you won't have troubles with the rendering, now about how to bake dynamics I'm not quite sure because I rarely use them but I'm sure a simple search in the browser will give you a couple of results
