Hello,

I am attempting to rip karts from MK8 and everything is going smoothly except for the fact that I cannot get normal maps.

I used BNTX Extractor to get .dds from textures.bntx which classified the normal map as a BC5_SNORM.

I've tried many methods for converting this BC5_SNORM .dds to a .png such as using CompressonatorCLI and Photoshop, but I am yet to get anything that looks like what I'm expecting (see attached image for result).

What is the typical method of getting normal maps?

Many thanks!

Try viewing the texture in Noesis. That should make it render as a regular Normal map.

Some of the normal maps are rendering completely white. Is this a common problem?

I managed to fix my problem by using a different version of bntx_extract (v0.5) instead of (v0.4)!

Just use https://www.irfanview.com/ and save the texture as .png?
