What format will allow me to copy a texture on Android in real time?

Hey folks,

I'm building a simple painting app for Android and want to be able to copy from a default texture to a new texture and then write my paint to it using a Render Texture.

Everything is working just great in editor, but the atlas texture (Default, read/write enabled, RGBA 32 bit) is not displaying correctly on the model (a house) when in Android.

Code (CSharp):

1.  baseMaterial.maintexture = new Texture2D(houseTexture.width, houseTexture.height, houseTexture.format, true);
2. Graphics.CopyTexture(houseTexture, baseMaterial.mainTexture);

Does anybody know what kind of texture format I should be using to ensure it displays in Unity Android? Have tried all options available under Format in the image import Inspector, and I'm just getting a grey box with seemingly random lines, or the object is covered in one of the main colours (a pastel peach) from the texture (suggesting a UV issue?).

I'm honestly baffled, and if somebody has experience with this I'd be most grateful.

(Bonus question: Does anybody know why VS2017 wouldn't be able to see my USB-attached Samsung TabA via debugger tools?)

EDIT: So, I'm running my .apk with the Logcat settings found on [this page][1] and all I'm getting are standard errors, no suggestions of what's causing the problems - I thought I might find something indicating that Graphics.CopyTexture isn't working, but no dice.

The current import settings for the 2D texture atlas are Read/Write Enable == true, with the format as RGBA 32 bit - and all I'm getting is just a grey/white texture on my model (which, ideally, should display a copy of the original house texture). Again, this all works in-editor.

 

Why don't you just reassign your Render Texture work in progress texture to the material used to render the house, which I presume is a MeshRenderer pushing out a 3D object?

 

That might have worked! As it is, I solved the issue by using GetPixels32 on the textures, making sure to call .Apply() on the destination texture. Thanks...!
