Render Textures quality degrades with multiple renders

Unity Engine

How can I prevent the texture quality from actively degrading, when I render a camera to a texture recursively?

Curved lines slowly turn into jagged edges over multiple renders. Filtering hasn’t helped because any added blur or enhanced sharpness is compounded by the next render.

Where is the “absolute 1 to 1 quality no matter what” option? Surely we’re not all restricted to low quality rendering?

You can use a stencil buffer to mask each level of recursion and render everything relative to your base camera. Since you are rendering everything into the same buffer (can be a render target on your base camera or just the screen buffer), you will get cleaner results.

Thank you for the tip! I will look into that.
