When there is a giant oak tree, it just shows the oak wood logs that are not turned sideways,

Kinda annoying if you ask me because the only reason i added xray for giant trees is to find those sided logs xD

Lol, It's because they have different meta data. You can add all 4 states of meta data into the xray Gui and it'll show them all. Should be as simple a 0 - 3. I'll take a look at this as see about finding a way to locate blocks that have specific position meta states

how?

Add the type of Wood that you want then edit it and change the meta of the block. You can do this in the latest version of the mod :D or though the config.

Note to self, Solve this by adding an option to highlight all blocks with that ID and ignore the meta of the block. This should be simple enough.

@SpeTheof Thanks for the report.

This has been resolved as of #50
