Hi!
I tried to upload my game to itch, but it looks like there is some kind of a problem with a texture:
And it’s visible in canva, that one model (rocks) is black instead of white:
HTML5:
Works correctly in Editor’s build and on Windows and Linux:
It uses the very same material as all other assets, but there is this texture assigned (it’s a 1x1 white pixel):
^ Yes, I attached it here.
I guess it can’t be 1x1, because all other models with other, bigger textures works and when I change the texture on rocks for the other e.g. huge texture with brown color - it works (on right):
So there is simple workaround for this issue, but I would love to hear if it’s intended or not (since somehow I love to use 1x1 single solid color textures, because why would I need more information from a texture, if it’s for a solid color surface? 
)

EDIT:
Looks like 4x4 is the minimum dimension of a texture that works
