Oh my god, you’re genius! Thanks!
Time to resurrect my little jelly!

Cool! Let me know if you run into any issues

One thing I am curious about , are the spheres themselves in the distance field? Static meshes are in the distance field by default if they cast shadows and have ‘Affect Distance Field Lighting’ enabled. If the spheres are in the distance field, usually you get a distance of 0 when you do a DistanceToNearestSurface with your own position. But if the spheres aren’t in the distance field, they would not squish each other.

Ah! That explaines the strange results I got at positive location. They all seem to be 0, unless you are inside another distance field, which now that you explain it makes a lot of sense. The colliders are less than half of the actual sphere size. It probably sees it as the nearest surface since you are inside it, which is closer than your own surface since you can’t get inside yourself.

Wow awesome sample. I donwloaded your contnet file and put its content in the content folder of a blank project. When I tried to open the map like in the video, I found nothing. I opened the contetn folder in the editor and I found nothing there too. How to use the content folder you provided, Thanks.

Very cool but I can’t open the assets in the UE4 (I put the Uasset on my content fonlder but nothing) any ideas?
This is very cool I have already test the Flex Nvidia soft body but you need to compile the Ue4 source from the ue4 flex branch and I get a lot of but soo that cool to be integreated in the 4.8 .

Make sure you are working in the master branch from GitHub. It’s Unreal 4.9.0.

I was thinking about a stealth game where your character cloaks near walls and uncloaks in the open. But you could use it for snow piling up more around buildings, or leaves, or trash.

I though this idea was cool, so I made it for you. Hope you like it:

Distance Field Cloaking

Here is the overview:

I would still suggest also looking into using the depth texture, since it makes more sense from a natural standpoint to base the distortion based on the distance behind the object from the viewers perspective. It also has the benefit of not needing DX11. But I can understand how the distance fields help to make an effect like this more gameplay consistent with distance fields. Especially in multiplayer.
