It seems to be a common problem with 1.8. Minecraft does not automatically create the resourcepacks folder anymore. This is ok for people who upgraded from an older version because they already have the folder, but not for new profiles.
If you cannot find your resourcepacks folder in your minecraft folder,
Create a new folder, in your minecraft folder, and name it "resourcepacks"
If you cannot find your resourcepacks folder in your minecraft folder,
- Create a new folder, in your minecraft folder, and name it "resourcepacks"
- Put your resource packs in there.
This should be added to the FAQ.
