Projecting low resolution onto a full screen high resolution

Unity Engine
1

Hello,

I’m trying to find a way to project a low resolution window in full screen without distortion. The resolution size is 420 x 240. I see it’s not as simple as saying Screen.SetResolution(420,240,true); This distorts the image. I have code set up to do letter boxing based on the ratio of the screen the game plays on in comparison to the aspect ratio of this resolution , but it doesn’t stop the image from distorting past the letterboxing…it simply gets drawn under it unfortunately. I do not expect the image to take up the whole screen obviously. Just want this resolution to size up as much as it can without distortion. Can anyone lead me in the right direction as to how I go about this?

Use rendertextures (requires Unity Pro).

Thanks; was looking at it’s properties in the Unity Scripting reference. Could you help me define an algorithm to achieve this? I was looking at “RenderTexture.active” but I’m not sure if it’s as straight forward as that example since I don’t have experience with the “RenderTexture” Class
