The region of the render target to read from. The horizontal pixel position in the texture to write the pixels to. The vertical pixel position in the texture to write the pixels to. If this parameter is true, Unity automatically recalculates the mipmaps for the texture after writing the pixel data. Otherwise, Unity does not do this automatically. Description. Color or depth buffer part of a RenderTexture. A single RenderTexture object represents both color and depth buffers, but many complex rendering algorithms require using the same depth buffer with multiple color buffers or vice versa. This class represents either a color or a depth buffer part of a RenderTexture.. What the fragment one does, successfully, is.

If we do the math, 401 pixels x 3 bytes = 1203, which is not divisible by 4. Some image file formats may inherently align each row to 4 bytes, but some do not.
