hello guys, ,i have this weird problem , when I'm in creative mode i see all mekanism tools or machines everything ,i can play with those and all that , but when I'm in survival mode i can't see or craft any of those tools , nothing at all no machines nothing , like the mod isn't there at all so ,.. maybe I'm missing something here if u guys have a solution for that , that would be great, thanks a lot :)

Try using NEI, it can help show you the correct recipes. Closing as this seems like a user-specific issue.

yeah NEI works just fine , i was using crafting guide .. thanks a lot :)..now i have a problem with the texture , i fixed that by deleting optifine , though everything was working just fine till MC crashed and the textures isn't there no more !! so i had to delete optifine !!
