  1. I ended up switching to volumetric stencil shadows to get a shadow directly under everything that has a shadow. Right now the perf is acceptable, and hopefully it stays that way as I add more objects that cast shadows in the game.
  2. I'm using raw DirectX 11 with my own shaders for this game. I tried moving the light to be 93 millions miles up, but then I still need to give it a z component that matches up with the player's ship. This continues to give the effect of the shadow directly under the player's ship, but shadows for other objects not staying underneath themselves. I may have to find a way to fake it unless anyone has any better ideas.
  3. I'm writing a D3D game where the player's ship flies along and casts a shadow nearly directly underneath to give a clue to the player on the height of the ship. I'm attempting to make this a directional light by using an orthogonal projection for the projection matrix of the single light. As the ship moves forward, I update the location of the light so that the shadow remains the same relative to the ship's position. The problem is because I move the light, shadows for other objects move relative to the light, instead of also staying underneath their objects.   (I'm purposely darkening the shadows so that you can see them better.)   The blue ship is moving forward and the gray ship is stationary. Note where the shadow is for the gray ship.   The blue ship has moved forward. I've moved up the light so that the shadow stays under the blue ship, but I need the shadow under the other ship to stay under itself too. Instead, its shadow moved up since I moved up the light to chase the blue ship.   I feel like this should be easy to fix, but so far I can't figure it out. Thanks for your help.   Steve
