AutoDesk Smoke :: Using Motion Vectors To Control Texture Movement?
Feb 2, 2013
I'm specifically looking into using motion vectors to control the position of a texture. For a better idea of what I mean. See this video, especially at 1:08

I'm sure some people will call this the "Paperman" effect.
I see a lot of information out there on how to use motion vectors to do motion blur, but not much else. I'm sure they are capabable of soo much more! All that movement information from 3D in a 2D environment sounds great!
I have motion vector channels correctly exported from Maya and I'm wording which CFX combination I would use to composite a texture in a way that it was controlled by the movement information of the motion vector channel.
I'm trying to use motion vectors that I rendered from Maya 2011 using Mental Ray's 2D Vectors for Toxik preset. The vectors work for blurring in Toxik and Nuke but when I bring them into CFX, the Motion Blur node goes crazy and shows arrows going off in all different directions. Is there a different format for rendering motion vectors from Maya for CFX or is this a Smoke 2013 bug?
I have a shot with handheld camera. I like the movement but it´s a bit too much. So i want stabilize it, but just take off let´s say 50% of the movement. Is that possible in an easy way?
I edit in FCPX and do effects and stuff in Smoke2013.
I have a shot done with handheld camera from helicopter. The camera is hung by a system, and we have a small gyro on it. But not yet a wiscam or other cool stuff.
So, in fcpx I can us load and lock X and it is really a beautiful steadycam shot. How do I do that in smoke.
The auto stabilizer does not give me a smoothcam version. And normal stabilizer is just for doing 2D stuff....
The shot, is a helicopter flying around an oilrig, and a nice horizon as well. It is orbiting the platform. So I have at least 90 degrees flying around the platform/oilrig.
I'm coming from a Symphony and FCP background. I do a lot of keying in the timeline when I'm finishing, so I'm often moving the green screen clip from track 1 to 2 and then putting the BG on the lower track. I'm used to being able to constrain the movement of the clip so that it doesn't slide around on the timeline and get out of sync when I move it. Does smoke have a hotkey for this? I've noticed if I hold shift, I get some indication of where Smoke is lining up the clip relative to other clips by some highlighting, but this does not constrain the clip I'm moving.
I have a bunch of shots in which I have to place layers of smoke in z-depth. I found out that there is a plugin system for Nuke called YUVSOFT which does this but the company will not release their plugins for small market jobs. The depth maps don't have to be anything special or perfect. I just don't want to have to spend days and days rotoing out a 30 or 40 layers per shot with Mocha. Will the Motion Analysis node create the vectors to assist in depth map creation?
I tried different things, like pixel spread, shrink, etc but I don't seem to get a better key than in my screenshot...."I know there is a way in Autodesk Smoke that you can use to paint the hue underneath your faded image. Its called the wash paint if I'm correct."
I don't know how that should work though.... how to get rid off the white edges but keep the blur?

Is there any way to turn on motion blur in Axis on the time line like you can in Action?
I looked in setup and it doesn't seem to be there, hoping I'm just missing something and I don't have to hall this text into action and back each time it gets updated.
I've got a load of text whizzing about on 3d paths and an overall camera move. The thing is i want loads of motion blur on the text but NOT on the camera move itself.
I'm trying to do some basic motion graphic builds with logos, and mask shapes.
Is there an easy way yo bring in mask shapes, timed animation position or scale keyframes that I have in AE... Like Copy keyframes, or mask shape from AE, and Paste into Smoke...
There is a box below the Stablizer button. Pressing the Adjust Box for a while, it pops up with 3 options which are Adj off, Adj Axis, Adj offset. I've used "Adj off" all the time as default.
On the other side, there is one more Adjust box for Vertices. I don't get it either. I just used it set to "Adj Tangents" as any tutorial said.
I tried to understand it from user guide, but it is still unclear.
I have used smoke for a few years now, and one of the things that I find frustrating is the camera controls in action.Would it be possible to have a control hotkey set-up like maya/XSI/3DS? Some other softwares allow you to choose the keyboard set-up.
Using the maya set-up: Alt - left mouse : tumble Alt - middle mouse : track Alt - right mouse : dolly
This means while looking though the lens you can move the camera in any orientation, you only need to hold down the alt key and use the 3 button mouse/Wacom to navigate.
When i scrub playback control in the cfx , it's slower compare to if i scrub the same thing (same viewport layout) inside the timing editor timeline. In timing editor the scrubbing response is a lot smoother even when we're looking at the same objects on the viewer. The playback control need to be fixed.
I know most of us have 2 computers in our suites and would be nice to controll both computer without having to use 2 mice and 2 keyboards. Right now I am using 2 computers, a mac pro and a macbook pro. I would like to use my MacPro's keyboard and mouse to control the macbook pro much like a mouse and keyboard on a second display. I've been using an application called teleport, but it doesn't allow me to use keyboard commands.
I've heard/used synergy, but it's to much work for the final product.
what i like in fcp, i can easily doing cut very fast, because the clip is not 'sticky'. So i can grab the clip and move and i got a very 'light' drag. The timeline is more 'slippery' ... i don't know how to say it. The drawback is : it's sometime become too sensitive so i can easily by accident move the cut and mess up the edit. I become paranoid , so i have to hold my breath while clicking :-) . But again the pros : it's easy to do fast edit or to crumble cuts around.
In the other hand .. what i like in smoke , this will rarely happen that i accidentally move the clip while i intend to click it. It's more 'sticky' to the timeline. So there's like more friction while try to drag the clip (only when first click/drag the clip not when the clip is already floating). The drawback is sometime i feel , it's hard to do some fast cut just by moving the clip around. :-) well, as usual, if we have 2 options, option A and option B, then we will tend to ask : do i have option C ( somewhat between A and B) ?
I'm asking is there any sensitivity control while i drag the clip. So it's between FCP and SMOKE. Something like a 'treshold' parameter.
I'm noticing with the new 2012 released, start up times are much slower. This seems to be caused by a 3 minute long control surfaces: intialising.The only control surface I'm using is a Intos tablet.Is there anyway to by-pass this?The .cfg didn't seem to have any control surfaces line.
In gmask, i switch the softness to 'tracer' so i got individual control of each the control points (cp). But seems that the feather's cp doesn't have its own tangent control. Is is hidden ? how can i turn it on ? or is it not available ?
How does one implement the use of two pivot points to control movement concurrently in the X- and Y-plane?
I 've added a Link Constraint to the salmon colored component which is linked to the red cylinder pin at far left. This pin has a Path Constraint to an Arc path which is orientated left-to-right and arching up. The pin at right has a line Path Constraint that moves down and to the right. Still image 01 shows the retracted position. Still image 02 shows the animation at 50%, the Fowler hinge follows nicely the path of the left most pin quite well. Notice no movement occurs in the down direction that would be imposed by the right pin - if it worked/was set up properly.
How to add a texture from a motion tracked footage (Motion tracked in Boujou) onto an object in 3ds max.
For example: Around 0:04 in this video [URL].... the guy smashes into the wall and it collapse. The wall is obviously recreated in 3ds max. But how did they make it so realistic? How did they take the texture from the wall and applied it onto an object?
How do you control texture mapping. Review the attached PDF for illustration on this problem.
My goal is to predictable create geometry in Revit that when a material is mapped to it the desired result will be achieved. My industry has a lot of objects created out of veneered wood, and solid wood forms. Revit is not giving me the texture mapping I am looking for.
We have numerous families to create, but the ugliness of the UVW mapping .......
I know that the AJA Kona 3 card has 2 outputs. Can Smoke send one eye to one channel and the other eye to the other of the Kona 3 card? Dual Stream output is what I am really getting at.
Is there any way that Smoke can see/output sub-blacks and super whites? Can't find any way of seeing them on my scope, Smoke just clamps everything. It won't even see anything below zero in order for me to make a correction on it, everything seems to be clamped on import. I'm using ProRes HQ footage.
What is the best plugin to do spline warps in smoke?(need something like the distort in flame) I notice revisionfx don't make a warper for smoke on mac.
