How to create a spaceship and force field transition effect I have put together a scene in which a space fighter exits a force field from a carrier. I would like to create an effect that when the fighter flies through the force field, the field glows darker as the ship transitions through it, then the field returns to it's original status once the ship passed through. The force field was created with a mesh and some shading. I then added a dynamic paint canvass to the field, and a dynamic paint brush to the ship but that isn't working. I am including an image of my setup. Am unsure at this point what to do. Maybe add a collision object? Can someone please assist me with setting this up? Am using Blender 2.91. With thanks
The effect I am looking for wouold be similar to this video on Youtube.

A sci-fi energy shield (force shield, force barrier VFX) is fairly easy to create with Dynamic Paint.

You just need ...

a subdivided plane that is the Canvas for the Dynamic Paint physics. Set Surface Type to Waves and tick the Open Borders checkbox. Add a Solidify modifier if you want to look at the shield from both sides.
an object (a spaceship or Suzanne) that is the Brush. Increase Waves &gt; Factor to 2 to enhance the effect
create a shader that uses the y coordinate of the wave deformation to colorize the shield. In the material settings set Blend Mode to Alpha Blend and enable Bloom in Eevee render settings. 

In Blender 2.92+ you can use a Vertex Weight Proximity modifier and Geometry Nodes to add some sparkle. Just create a vertex group (&quot;proxy&quot;), assign all mesh vertices to it, and use it in the Vertex Weight Proximity modifier and for the Density Attribute of the Point Distribute node in the Geometry node setup. 

In the example, both objects (the plane and Suzanne) have each a Vertex Weight Proximity modifier and a set of Geometry nodes to have the little spheres on both objects when they are close together.
