Textures loaded from bytes are pink in build

I am loading an image (just a byte array) into a texture and applying it to a plane. The image in question is a screenshot taken from the desktop and exists only in memory - it never gets saved to disk.

Here is how I am applying the image to the plane:

 var viewingPlane = new ViewingPlane();
 viewingPlane.Texture = new Texture2D(window.Width, window.Height, TextureFormat.RGBA32, false);
 viewingPlane.Texture.LoadImage(window.Frame);
 viewingPlane.Texture.Apply();

Don't worry about ViewingPlane, that is just a custom object for scene management.

Anyway, this works fine in the editor and my textures are correctly applied. However, in build mode, everything is pink/magenta.

The image is being created using another application I made and the DLL is added to my Unity3d project, where it is used to extract screenshots. The DLL is built for x64 and Unity3d is built for x86_x64.

When I check my output_log.txt file, I notice this:

Fallback handler could not load library C:/Users/Rich/MyProject/Builds/Main_Data/Mono/libc

Fallback handler could not load library C:/Users/Rich/MyProject/Builds/Main_Data/Mono/libc.dll

Fallback handler could not load library C:/Users/Rich/MyProject/Builds/Main_Data/Mono/libc

I've read all the questions/answers I can find on this and have reset shaders, etc, but nothing is working. I'm on Windows 10 and Unity version 2017.3.1f1.

Any ideas?

Pink = $$anonymous$$issing/broken $$anonymous$$aterial

Just to add to this, if it were a texture issue, you'd get the red question mark texture. So most likely, your shader is not supported or the material is missing.

How can the material be missing? It is never created on disk. It's solely in memory. The image is a screenshot of the desktop, loaded into a byte array and then applied to the texture.

@meat5000 If you'd read my question, it would be clear to you that I have Googled.

Um no? The word Google doesnt even appear in your question, so definitely wasnt clear, no. Did you make sure all the shaders you use are both compatible and included in default shaders list? You apparently must include variants. The link was simply so you can observe the extend to which pink = missing material, so you know what to focus on. Check your relevant shader includes a Fallback option within it.

Some people have said that in a case where everything is pink, its an issue with Image Effects. Dont know if this will help you? There is a chance this issue arises from working from a Protected Directory, such as Desktop and certain places in the Users folder. Try relocating to a folder just off the c: drive. C:/WOR$$anonymous$$/ Or something like that.

What shader does your $$anonymous$$aterial use? If you are creating the $$anonymous$$aterial in code then it could be that the shader is not being included in the build. You can force the shader into the build by going to Project Settings -> Graphics and adding it to the "Always included shaders" list.

(while the above is alluded to in meat5000's comment as "default shaders list", it seemed to be worth spelling out a bit more as a possibility/solution)
