Hi everyone , i want to replace some textures in Garena Free Fire (it's a popular battle royale game) with my own textures (grass,road,sky..etc).
i don't have any programming knowledge but i tried very hard , if you guys can help me to achieve my goal.
i tried to open OBB file with Rar And Replace some assets With Another Modified Assets That i made and use 'Store' Method for that but it doesnt work and what i get is just black screen .
Please help me to figure out how i can modified obb file and reimport it again without getting error in game and if you have any additional informations for me i will be blessed.
I searched for a mbs script for Garena Free Fire Download Link but i didn't find anything.
Garena Free Fire Download Link : https://apkpure.com/garena-free-fire-android-il/com.dts.freefireth

some developers adding or modifing their own flags and config (PK sec) in their zip file or crc checksum or size checker or file time match for their obb package, that is why they can't be read

and don't use freeware webs, most of free software webs injecting miner or spying plug to their apps

Ah I think it is possible, when I play the game I see the company logo after that nothing happens no error message or surprising exit.
Maybe you can give some advices to avoid this problem and if you have any unity bms script i will be blessed because the game engine is unity.
