Question by Seneral · May 03, 2015 at 10:42 AM · texture2dgetpixelsteps

Steps in Texture2D after writing values to an array

I'm getting "steps" in my texture after I

  1. Write it to an array of floats using Texture2D.GetPixel in a for-loop

  2. Doing my algorithm on the GPU (receives the image with steps)

  3. Writing to an new image with Texture2D.SetPixel - EncodeToPNG - File.WriteAllBytes

Even leaving out step 2, so just reading to an array and writing to a new texture, results in a texture with steps. Tested with a very smooth Gradient.

How can I avoid this? I really need a perfect representation of the input Texture2D in an array (my algorithm is calculating flow on it). Currently it screws everything up just because of these steps...

In the attachement is the result of just step 1 and 3 on an initially perfectly smooth gradient.
