With some texture packages I simply have a blackscreen and can't see anything
Check whether they are really for your version (attention, the current 1.4 was already there) and possibly need Optifine.
Most texture packages are made for a specific version.
So if you take a texture package that is made for version 1.8 but you play in version 1.12, you may get a black screen.
So always pay attention to the version.
I pixeled it for the 1.8 and I also had Optifine in it so neither of the above applies
You did it yourself And then I assume that you also play on 1.8 - on what basis did you make the texture pack?
That's not the reason for a downloaded pack, so I'm already using the right versions
How do you mean?
You said you pixelated it yourself, what does that mean?
I just pixelated it in paint and then put it in the tp folder
