Image information:

$ identify lauter_waterfall_4k.exr

As a workaround, use the HDR file provided by Poly Haven.

I also have this problem with Godot 4.3.1 and can not use normal map files

I meet this problem, too. My textures is provided by Poly Haven's blender plugin.

VaranauskasD commented 7 months ago

polyhaven by default now downloads .exr file type for normal maps download i.e. .png which is supported by Godot Screenshot_327

Same with exr e.g. from Blender <version>/datafiles/studiolights/world/forest.exr forest.zip (CC0)

modules/tinyexr/image_loader_tinyexr.cpp:70 - Unknown compression type.

It would be great when the compression is supported. It reduces the size around 7x in this case. It's terrible that e.g. hdr has not compression etc. Ok, in this case hdr file size is around half size of exr. Idk
