3. Enter a play mode.

Expected results: The scene is played without any errors.
Actual results: There an error shown in the console:
SetPixels32 can only be called on a RGBA32 or BGRA32 texture but is being called on TextureFormat(14)
GenerateTexture:Start() (at Assets/GenerateTexture.cs:12)

    Confirmed also same issue in Unity 2018.2.0f2
    On Textureformat.BGRA32

    "SetPixels32 can only be called on a RGBA32 or BGRA32 texture but is being called on TextureFormat(14)
    UnityEngine.Texture2D:SetPixels32(Int32, Int32, Int32, Int32, Color32[])"

    So, Issue tracker above says "fixed in future release"

    - Since 2018.2.1f1 is the latest version and this issue does not appear in the patch list:
    I'm guessing that is a yet-to-be-announced future release which isn't even in beta yet?

    Same issue here using a BGRA32 Texture2D, in Unity 2018.1.6f1.
    SetPixels32 works fine with an ARGB32 Texture2D, but requires expensive conversion code on each 32bit int to reverse colour byte order (endian-ness).

    LoadRawTextureData(intPtr,size) works fine with Textureformat.BGRA32 from the native framebuffer pixel data encoding without requiring endian preprocessing, but I need SetPixels32 for smaller rectangles inside the texture2D.
