smart uv project problem...

okay im following a simple video tutorial step by step, and i havent been doing anything differently.

when i select my object and use ‘smart uv project’ with default settings, the mapping is all skewed and on a slight angle. i have been screwing with this too long and cannot figure out what im doing wrong… .:RocknRoll:.

im going insane

edit: i recreated the object and magically it’s not doing that anymore… but the object is identical to the original one. what gives?

Well your object has this pyramid shaped bump on the sides. You are asking Blender to “flatten” it. You may know how it should be flattened. Blender doesn’t. It will do its best to flatten it.
