Did some testing, if i have optifine installed the leaves wont be fancy, i remove optifine and it's all back to looking fancy.

That's odd. I play with Optifine and it is transparent for me. You must have some settings changed that are preventing it from showing fancy leaves.

Can you try downloading the latest version of Unity from this repo? Try 1.12_plus and 1.13.

1.12_plus fixes it..

1.13 on MC 1.12 is a mess for me..

btw.. i made zero changes to the options. fresh install (made a clean profile on twitch app to test this)

1.13...

Thanks for looking into this so quickly. I must've forgotten a few changes in the 1.6.3 upload of Unity. I will see about updating that as soon as I can.

thanks for pointing me to the 1.12_plus. can't play MC without this texture pack. love this pack.
