In my game, i want to paint an effect onto the ground as an object moves around. Instead of putting down geometry, i’d prefer to update a texture so that nothing ‘expires’ and fades out. My rough plan was to have the object act as a ‘brush’ that updates a mask, which exposes the special effect material.
Has anyone done this in UE4? Is it a good path? Any tutorials on the technique, or is it just unworkable? The world is small (2ish screens worth) so I don’t think memory will be a concern if i just paint into a big 2k-ish texture.
