Question

few days ago, i asked a question about “how to display in a second viewport without redrawing everything”. One of the answers was “you should use a renderTarget2D and give a Rectangle source to the spritebatch”, this solution is without Matrix camera.

spriteBatch.Draw(
    TheRenderTarget2D, 
    TheViewportTarget.Bounds, 
    TheRectangleSourceFromTheRenderTarget2D, 
    Color.White);

That works very fine, but i lose a lot of render quality (because of my game zoom and some other things).

The question is : How to draw in the second viewport with camera.transform() to keep the quality, with zoom.

Hope you can help.

Answer 1

That’s it :

    Graphics.Device = viewport1;
    spriteBatch.Begin(,,,,,Camera1.transformation);
    DrawScene();
    spriteBatch.End();

    Graphics.Device = viewport2;
    spriteBatch.Begin(,,,,,Camera2.transformation);
    DrawScene();
    spriteBatch.End();
