Its a bit experimental and disabled right now, but it’s pretty straight forward on how to switch it on.
First some general picture of how it works:
- “Light Tanks” have option to spawn track decals, it can be switched on/off on each instance of the tank. These tack decal are not visible on the landscape in the main level (land vehicles) but are rendered on the copy of the landscape placed few hundred meters under the visible landscape. This is done to have a clean mask of white decals against a black landscape
- There is an actor in the level called GroudDeformationCapture. On this actor you can set a target reference - another actor and it will follow it around. What this “Capture” does is basically renders decals from the first step into a render target and blurs it. Capture can follow tank you currently control or can follow camera, the point is to capture ground deformation mask only around some point in the world which matters - where you should be able to see ground deformation
- Landscape material takes render target from step 2 and uses it to displace tessellated landscape.
To enable it, first switch on GroundDeformationCapture actor which is already placed in the level (it should have Disable option switched on) then enable Track Decals on the instance of the tank.
