when i try to start minecraft, after 30-40 seconds its crashing
on crash log i found "Could not find texture metals/aluminum/caution, and no custom texture manager was provided." What i should to do?

If you're playing in an instance without aluminum you should disable the aluminum blocks in chisel's config.

This will depend on where your minecraft instance is installed.
Find your /.minecraft/ folder. Then navigate to /.minecraft/config/.
Chisel's config should be inside of this folder. It should be called chisel.cfg.

um... how to find chisel config? xD

thanks you very much

It should be noted that that error is not a crash and would not be the cause of your game crashing.
