'Error Unity Texture creation failed. 'R32G32B32A32_SFloat' - Amazon Fire tablet

Hey, so I'm getting no 3d graphics when building for the Amazon Fire tablet. It worked about 2 months ago, but now it doesn't. I checked the logs and it gives me this error in every frame:

'Error Unity Texture creation failed. 'R32G32B32A32_SFloat' is not supported for Render usage on this platform. Use 'SystemInfo.IsFormatSupported' C# API to check format support.'

I've tried to search for any textures that might use this: 'TextureFormat.RGBAFloat' (I think that's the correct format? I couldn't see the same name as above), but I get no results. I also tried to search for non supported shaders and the 'Hidden/InternalErrorShader' appears in the Editor and Amazon tablet logs, but I can't find what it's attached to.

I've asked this on Reddit, if people recognise it, but need to ask in here as well, because I'm at an absolute loss.

Thanks for any help.

 

Correct, but it may declared as a RenderTexture. Try

RenderTextureFormat.ARGBFloat

and

GraphicsFormat.R32G32B32A32_SFloat

if you're going to use

IsFormatSupported

.

 

Hey, thanks for the reply. I was really hoping it was that, but unless I need better code to find the issue, it didn't return anything either.
I'm using this code to find stuff:

Code (CSharp):

1. foreach (var obj in Resources.FindObjectsOfTypeAll(typeof(RenderTexture)) as RenderTexture[])
2. {
3.     Debug.Log("resource render texture: " + obj.name);
4.     if (obj.graphicsFormat == GraphicsFormat.R32G32B32A32_SFloat ||
5.         obj.format == RenderTextureFormat.ARGBFloat)
6.     {
7.         list.Add(obj);
8.     }
9. }

It finds 3 render textures - 'SceneView RT', 'GUIViewHDRRT' and a blank one, but none of them have either of those texture formats.

This is the full error, if anyone is able to decipher it:

Well, I managed to fix it and I'm not entirely sure what did it.

I noticed Screen Space Ambient Occlusion was attached to the Universal Render Data, so I disabled that. Swapped between OpenGles3 and Vulkan (even though I knew Vulkan wouldn't work), enabled 'Allow downloads over HTTP', as I've been getting an editor error with that for ages after a Unity update and looked through any old plugins that were deleted, to see if any remnants of them were left behind.

I've a feeling it might have been the SSAO, since that could be trying to create a render texture on load.

Anyway, leaving all this information here, in case it happens to anyone else.
