I don't think vray can render motion blur by object

Can you render a velocity pass and do the MB in comp?

I'm sure I can, I just can't wrap my head around how to tackle it.

I've got a smoke trail (Afterburn) hitting a wall, and chunks that explode out of the wall and through the smoke trail. I've got the wall chunks set as matte objects so the smoke trail renders normally, and the wall chunks appear cut out from the smoke trail. I can then render the wall chunks on their own without the trail and comp them together and it looks great.

My issue comes from wanting the smoke trail to have no motion blur at all, while the matte chunks that fly in through the trail have motion blur. Is there a way I can set up a specific group of objects to render a velocity pass for, but ignore my Afterburn system? Pflow is the particle system I'm using if it matters.

Thanks for putting up with the noob questions guys, I'm at work and don't have a copy of Max here so I can't do a test on my own yet.

Vray motion blur issue - go to the vray properties in the object, uncheck 'use default mblur samples' and lower the samples to 0.

I can see where the option is, but it seems that when you set the mblur samples of a PFlow operator to 1, it just changes itself back to 2 as soon as I click anything else. I just tried it with a Superspray too, it just reverts back to 2 samples immediately. Very frustrating.

CubicleGangster, and EoinCannon thanks for all your help so far, I've got my matte issue resolved and that was my biggest problem. I'm going to keep plugging away at the blur thing. I enabled the Frame Buffer for the first time today and played with that, but I couldn't get After Effects CS4 to do anything useful with the .RPF files. Does combustion handle it better? I think I've got a learning edition somewhere... Back to the books.

Hm, really? I find it to be a pain. Used Nuke for a few weeks then started using Shake full-time at work -- I much prefer Shake to Nuke, though it may just be due to exposure. Tried using Fusion again (it's what I started with), and I absolutely can't stand that poo poo. Ugh. Eyeon needs to get their act together.

heh, we're using Shake at work right now, I can see why some people like it, it's simple :-P , but good lord is it slow. I just find Nuke so much sleeker and faster.

^^^^ Shake is just very simple in the way it works, it's very into the whole fundamentals of compositing operations, over, gamma, color correct, invert, all these operations which are pretty much the basis for compositing.

While Fusion is more compressed down with it's nodes, merge is pretty much all the layering operations into one, where as Shake has them separate in Over, Add, Subtract, Multiply, and so forth.

That's nuts, I changed the EXACT same value, PFSource instantly changes back to 2, but PFSource->Event 01 will stay at 1.

Maybe I need to select them both at once and change the value. That's the only miniscule difference I can see comparing your window to mine.

I'm using VRay 1.5 SP2, and Max 2009, could it be a version issue?

Thanks a lot for the pointers, really. You can't get specific help like this on big CG forums.

Though Nuke also has 'Merge' with a drop-down, or you can choose an Add ("Plus")/Mult etc command which is the exact same as the aforementioned 'Merge' except it's already chosen for you.

Is Shake slow? I've never used Nuke in a production pipeline, just on my own. I can definitely see how it'd make the comp cleaner, what with channel support, but all the more complicated too.

I agree with the sleek bit. I went from Fusion to Nuke to Shake, and now looking back at Fusion it's a dinosaur. It's so.. clunky. Pain in the rear end to do anything. Nuke is gorgeous -- smooth, flowing, everything right at your fingertips. (Love the 'tab search' node creation feature, a la Houdini. All comp programs should have that.)

EoinCannon posted:

As stated before, I personally find Fusion to clunk along very slowly compared to Shake (or Nuke). The attributes menus don't 'flow' as well...

I understand I'm being vague. I can't really describe what it is about Fusion I don't like. I was perfectly fine with it before I started using anything else, but now I can't go back to it. Maybe it has something to do with bearing a strong personal grudge against somebody I know at Eyeon, that may be it.

Eoin - if you're using a Mac, look into Shake or Nuke. If PC, check Nuke out.

Don't worry about software differences, it takes but a few hours to figure out another comp program once you're settled into one. Went from never using Shake before to doing full comps the next day - easy transitions.

Edit: I know I brought this up before, but does anyone else think we should split this into two threads? 3d & Comp/VFX?

At least here at work our Shake setup is pretty slow, might be cuz it's a big company, 2k plates, all that crap. But Nuke is really fast, remember, they stopped developing for Shake about 2 years ago, Nuke just released a brand new version, 5.2, so it's getting updated more and more, oh and it's insanely fast if you got a raid or fast transfer rate going, mmhh real time DPX.

And yeah I wouldn't mind having a split thread, so we don't bother some people with our software, production, client rants :haw:

I just played around with it, and I think I'm just encountering a bug, if I type 1, press enter, then immediately close the window my changes take effect, if I click anything else in the window other than Close, my mblur settings revert.

It turns out I probably did have it working a bit last night, but in the tests I'm doing right now there is a moving camera, and that adds motion blur to the entire scene even when one object's motion blur should be turned off. It works perfectly with a still camera, but since I'm camera tracking I guess there's just always going to be some blur.

EDIT: The slight motion blur isn't really perceivable, and actually matches my plate nicely. Here's a quick test I threw together last night. After Effects since there's been lots of comp talk lately. Thanks again.

Here is a technical question which seems obvious but I can't seem to find an answer. How does one see and type in global / world-space coordinates for an object in Maya? I am not talking about the transform numbers in the channel bar or the attribute editor but the absolute world position. In Max you can see local vs global coordinates pretty easily but it never occurred to me how to do the same thing in Maya. If you import an object, often it is far out in space and has zero transform values. How can you see the global transform values for an object from the origin?
Just curious if anyone knows what I am talking about, or is this yet another dumb question?

You can do `xform -q -ws -rp` to get the worldspace position of an objects pivot point.
If you want to set position in worldspace you can do `xform -ws -t x y z`

For the problem with imported objects, here is a tiny script I made a while back that might help if you do that stuff often or on a lot of objects.
It just centers the pivot, moves the object to origo and freeze it, then moves it back out to where it used to be. If you don't want to freeze rotation/scale just change the makeIdentity r/s.

code:

global proc freezeMove()
{
	string $objectList[] = `ls -sl`;
	string $object;
	float $orgPos[];
	for ($object in $objectList)
	{
		xform -cp $object;
		$orgPos = `xform -q -ws -rp $object`;
		move -rpr 0 0 0 $object;
		makeIdentity -apply true -t 1 -r 1 -s 1 -n 1 $object;
		xform -t $orgPos[0] $orgPos[1] $orgPos[2] $object;
	}
}

You could also use xform -q -bb to get the boundingbox and calculate stuff from there if you don't want to touch pivots/freeze things

That's so awesome. I definitely want critiques, but that was just a placeholder to make sure an afterburn system would work. Shadows are my next hurdle, I'm having difficulty rendering shadows without the object that's casting it, but I'll get it.

I enjoyed this about his posts, he would usually do it to people who really deserved a taste of reality, even if they could sculpt well (its hard to reach those types). Although he did hold a lot of grudges and was relentlessly incessant about persecuting certain people's work to the point of just becoming noise.

Never saw his work, but the jokes on him I guess.

Prisoners don't like pedophiles and the "but it's for artistic reference!" bullshit is not going to fly in front of any judge or jury.

Burn in hell.

/edit

After reading a few of his posts, I know the type of artist he is. Especially when another guy did a painting recreation that got featured on a few other websites, he got his nose out of joint and pretty much dismissed it as one character with a simple background... you know, because he did one with 100's of characters and therefore his is better.

Weird thing with this is that any image anyone ever did with a fairly scantily clad girl in, he'd loving flip - say it was close to a perversion, that it's not real art, that they're just making the images for some form of gratification.

And it turns out he's been filming a 12 year old for years.
