After Effects 3d Displacement Map

[Umbelina Baublitz]

Inmy case this was caused by something in After Effects' preferences. I'm not 100% sure what actually fixed it as I was digging through and testing any available toggles, and I'm not sure which one actually had an impact - something related to previews or acceleration I think. Didn't make any changes to my video card drivers or settings so that definitely wasn't my issue.

If you replaced the light blue solid with a shape layer filled with a multi-colored gradient, applied Chromatic Displacement to the Shape layer, and selected the image as the source you would have some color values in the source file you could use to displace the pixels in the Shape Layer gradient. If the shape layer was a solid color there would be no pixels to move around. The other option would be to just apply Chromatic Displacement to the image Use the image as the source, and crank up the Displace amount.

Yes that's the one.

I did Select the mask and Effects. Same result black screen. Then i've tried applying the chromatic displacement on the image itself an cranking up the Displace amount, same thing black screen. I'm now wondering if this is due to the fact that i'm using a trial version but all the other plugins in the RG VFX suite are working fine, I'm puzzled.

Did you make any discoveries with this? Just added the VFX Suite to my collection and notice I get the same black screen with any of these Effects, Chromatic Displacement included. Comp screen goes black immediately after adding any of the Effects, without adjusting any properties. Have played with all kinds of Project Settings, bit depths, software/hardware acceleration, changed my Monitor from SDR to HDR and back, all to no avail. No problems with any other Effects, Red Giant or otherwise...

It seemed to be an issue with after effects registering my other graphics card. Because I am using a laptop, I had to change all of my Nvidia settings to direct to my 3D graphics card (Nvidia) but sometimes it would cause a black error as it was using my default Intel.

Dude, I had the same problem, too. After some efforts, I found the solution.

The problem is caused by the Video card. if your graphics card is out of date, update it. If your graphics card is up to date, upgrade it to previous versions. and the problem will disappear.

You saved my day. I had been trying to reinstall back and forth the VFX pack but can not solve and I even checked my graphic card it was up-to-day but I couldn't solve even though switching between gaming version and the studio one. Then I tried to update my on board graphic card, things turned out it was the problem and then problem solved.

Hello have the same problem, could u explain better the way u solve it pls, also i hve the problem with supercomp which is empty when i apply it (i mean the supercomp panel is just on white). also i have to say i cant effort to pay the original license :c am just a student

Not yet, it's so frustrating. VFX suite works fine for me except for Chromatic Displacement. The Red Giant team told me I have an inadequate CPU for my RTX2070 but it's among the best compatibilty wise.... Can someone please explain ??????????

Originally I had multiprocessing on and the render time was 24 hours! A friend suggested taking off multiprocessing and it went down to 4 hours. I had to shut down the machine over night and when I came back and restarted the render it jumped back up to 46 hours to render 3 minutes of video as shown in the screen shot.

And as I understand it the reason multiprocessing was running so slow was because there was a bottleneck at the hard disk trying to read and write at the same time. When I turned off multiprocessing the render time greatly improved, but now after restarting, the render time is even worse!

In an ideal situation, your cache should be placed (a) on your fastest disk (b) at a physical location that is different from your source footage. The idea here is to not have a single disk perform read and write instructions as this will slow performance, greatly.

I have no idea which of your two disks is faster. Having said that, in your specific situation, where there is only one source footage and a lot of writing from RAM to disk cache (due to the Time DIsplacement effect having to read a lot of before and after frames, which I safely assume will very quickly max out your RAM), it may be a good idea to place the disk cache onto the same disk as the source footage IF the source footage is currently on your fastest drive.

AE is multi-threaded regardless if you have switched on Render Multiple Frames Simultaneously. IOW, multiple processors will be enabled regardless if RMFS is on/off. Further, there is a disconnect in your Q as you are addressing two separate issues.

Well it looks like ramping the effect down seems to have a good effect. At 70 sec displacement the render time dropped to 9 hours, and now I just turned it down even further to 40 sec and the render time has dropped to 2 hours!

I had actually read through that page earlier, I guess I should be more specific by asking why does the render times take such a huge hit when turning on Render Multiple Frames Simultaneously. I assumed from thread that my problem might be that the disk drive was not reading & writing fast enough:

One thread should be fine. By now you should have a better grasp with using the Time Displacement effect and how to optimize the settings for performance and temporal quality. You should also have a better idea of how multi-processing works and how to optimize your system under different project types.

I am quite new to touch designer and I am encountering an issue with the displace TOP.

I am trying to replicate the effect I saw being done in Photoshop. Where it is possible to stack different effects on top of one another, resetting eventually the original effect, by applying the same effect in reverse.

EDIT:

Here is the video example:

Here you can see how the layer is first displaced in one direction, then a filter is applied, and then displaced in the opposite direction.

That destroys data but the skull comes back at a later stage, more than my beans did .

Oh wow, then it was much easier than I thought to replicate. It is literally the second time that I try to tackle TouchDesigner so I am still not familiar with all the features. Thank you so much for the examples and the effort!

Maybe, although the logic would make sense (in my head anyway) this just cannot work.

I think the nature of noise displacement is somehow different form the concept of twirling an image?

I am not sure.

Great to come with knowledge from other packages and try to rebuild things here. It really gets you to understand the platform and also allows to bring criticism on how things could perhaps be improved.

Hello, i am trying to determine the deformation caused by an earthquake in our study area. I have already made the displacement map but i am not sure if the results are reliable since their are displacement values on areas covered by the sea.

I am relatively new to InSAR processing so any response would be of great help. Thank you!

Please have a look at this tutorial: Displacement mappping with Sentinel-1, especially the notes on limitations and the selection of suitable images.

Based on your coherence it does not make much sense to derive coherence for such large areas while only the small part at the coast has a coherent phase signal. Accordingly, the unwrapping produced random results.

Does masking out areas with low coherence before unwrapping help? If not, what can you suggest I should do? The image pair I used is the shortest possible time interval available on Sentinel before and after the earthquake happened. Thanks for your reply!

However, after unwrapping there are displacement values on the masked areas. I would like to ask if the masking procedure that i did helped in unwrapping or it didnt have any effect on the results at all. Thanks!

I have a problem with the final displacement. As you can see from the image, there is over 6 meters of displacement, which is impossible. I followed the TOPS Interferometry Tutorial step-by-step and got no errors. I am open to any suggesstions.

Motion Mosaic offers a set of powerful features for generating truly unique effects. Specify both an icon layer and displacement layer and set the number of units. Toggle between rotation, scale, both or none for the displacement effect. Control the intensity of the effect independent of the displacement layer. Adjust the rotation, scale and time offsets. Toggle a border on and off and specify its color. Set color swatches and use them to map displacement layer values to icon layer coloring. Map the displacement layer values to icon layer time. Map the displacement layer values to icon layer transparency. Adjust the random engine seed value. Since every control is fully animatable and keyframable within After Effects, the possibilities are endless.

Motion Mosaic produces effects not otherwise possible when using animated icon layers. Map the animation timing to the displacement layer so as to offset timing by constant, horizontal units, vertical units, displacement and inverse displacement.

Motion Mosaic is capable of working in 8 bits per channel and 16 bits per channel color modes. It is recommended to work in 16 bits per channel color mode so that the displacement map can provide 32,768 levels of luminance as opposed to 256 when working in 8 bits per channel color mode. While Motion Mosaic will also work in 32 bits per channel color mode, it will down-convert 32 bit float values to 16 bits per channel.
