Assertion failed: Assertion failed on expression: '(destWidth >= srcWidth && destHeight >= srcHeight

Using Unity 2017.3. I'm getting this error:

"Assertion failed: Assertion failed on expression: '(destWidth >= srcWidth && destHeight >= srcHeight) || (downscale && (destWidth * 2 == srcWidth) && (destHeight * 2 == srcHeight))'"

which seems to have no consequence? every time:

I build
I open a scene
I build asset bundles

No idea where it's coming from. Any ideas what this is?

 

You could switch the Logging options for Error, Assert and Exception to Full. This will include more information if this error occurs again, which is perhaps helpful.

Thanks, I'll check it out. Hasn't happened in a while, but I'll report back what I find.

 

Ok, I'm finally back into my project again. Here's the output I've got:

Looks like its an ETC2 texture thing. Now to find which texture is causing this

 

Well I think I've found the issue:

In build settings "ETC2 Fallback" = 32bit, half resolution was causing the errors.
I've changed to "ETC2 Fallback" = 32bit and now no errors... yet

 

I'm getting the same... but I want half res fallback.

 

I'm having similar issue for the non-rectangular texture (2048x1024) with ETC2 and fallback: "32 bit half res" on Unity 2017.4.11f1
Seems like there's no other issues about it.

 

Has anyone filed a bug report about this?
