The problem looks like this.
I was trying to import my own interface textures but have green squares instead.
So client doesn't like my textures.
Okay, I've checked blizz textures' format with BLP Lab and it can be described like:
Signature: BLP 2
Compression: DXT 3
Alpha bits: 8 bit
Picture type: texels + alpha
Mipmap count: 7
Header size: 1024 bytes
My blps after blp converting from PNG have this description:
Signature: BLP 1
Compression: JPEG (baseline)
Alpha bits: 0 bits
Picture type: RGBA image
Mipmap count: 7
Header size: 292 bytes
JPG quality: 50%
WxH is the same.
So, my question is which rows in the description are critical to client reading.
What convertation parameters should I change to make my blps work in client ?
And what soft is better for this? Maybe this is the problem? Cause I use BLP Lab atm and it doesn't have much convertation parameters.
