I just downloaded an epic texture pack and when i started using it there was a tiny picture of fire on every grass block, the water was a shadeless grey like some sort of bottomless pit looking thing, every piece of thing that had to do with wood is the same colour as the water and finally some objects in my inventory are invisible (that's why i couldnt find my emerald.

PLZ HELP (and if u send me a link to texture pack wiki read it and it didnt help me)

You have to either use MCPatcher or install a version of Optifine into your client. What you are trying to do is use a HD texture pack (In MC, anything bigger than 16x16 is considered HD and the game doesn't know how to display it correctly.

I have a feeling he wont know how to do that lol.

This guide should help.

me already have mcpatcher but how do i install it in2 my client?

You don't

Just run it and hit the 'Patch Minecraft' button.

EDIT: It might be 'Patch Texture' or something if its not Patch Minecraft

it only said "patch" and "patch and run" so i chose patch and it didnt work at all <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/2639.svg?0" type="image/svg+xml" standby=":(">:(</object>

Remove the texture pack you already put in the texture pack folder.

Then patch it again.

Then install the texture pack again.

by install do u mean download again?

I mean put it back in your texture pack folder and select as the texture you want to use.

well then thats no working
