Vray values are not animatable?

[Morbid Angel]

Just stumbled accross of this now. Tried animating the duration of motion blur and found that its not animatable, and would like to know why?

[vlado]

Some V-Ray parameters can be animated and those appear in the Track View. Having animated parameters complicates the operation of V-Ray somewhat... As far as the duration is concerned, we didn't see any practical reason to make it animatable. This can be changed, of course. Why do you need to animate it? Also, a work-around is to render a sequence through MaxScript and change any render parameters between frames.

Best regards,

well since vray render time is affected by the amount of motion blur which is in current frame (I read this on 3dcenter.ru) they wanted to animate motion blur to become 0.0 and save up on render time. When I thought of that and tried it thats what I stubled upon.

Which brings me to another thing I wanted to ask you, if it's at all possible, is per object motion blur. So that some objects can have blur and come can be exluded from it.

Second that request - A lot of the renders on the canadian milk ads had stability issues due to memory handling and since an object can be taking up extra ram for blur processing without needing motion blur it's a bit of a problem.

No doubt we don't need to point this out since everything you've put in to vray up to this point is pretty damn efficient

I "third" this request. It would be helpful to animate the duration of motion blur.

and not only that. Lets say you have an object inside of the interrior. You need nth number of gi subdivisions to illuminate interrior and etc. Then the object leaves interrior and is now on the exterrior where you dont need so many subdivs. So animating numbers of samples cast would also be benefit.

yeah lets say you want to do that crazy skinny shutter effect like on gladiator.

This has been wished for before but with no success. I would like to have animated vray parameters too but not just Motion Blur but a lot more settings, would be so much easiere to find the right render settings if you could just animate them and send them all of to the slaves and analyze all the images afterwards to find the ones with best quality at the lowest rendertime.

I secon that!

did you look at the new scene states in max 7.5?
looks nice to try a lot of settings etc. in one go.

[suurland]

Plastic_ not sure you asking me.. But I havn't I havn't updated to 7.5 think I'll skip it and jump to max8 instead. Also it could probably be done with maxscript but I don't know anything about scripting so it had to be very simple.

Hmm, that is an interesting idea, could be scripted... the question is what parameters to adjust and how much.
