How to flip normals with multiple meshes at once?

[Nadimos]

Hi, does anyone of you know how one can flip the normals of multiple meshes at once in blender without having to go into edit mode for each individual piece and flip them there?

 

I feel there gotta be a script or some shortcut avaible for this task, but i cannot seem to find it.

 

Atm i am making clean versions of tilesets and changing 10 diffrent textures in nifskope+normals is so slow, i rather mirror the mesh in blender instead

of having to click like crazy.

 

The monotony. :facepalm:

 

I already changed ~600 textures yesterday.

:ohdear:

 

Need to find a smarter way. :psyduck:

I have noticed that if you join objects, and then export, they will not be joined anymore. I don't know if it's a bug or a feature, but it seems like you could use it to your advantage either way.

i.e. join all your objects into one. Go into edit mode and flip your normals. Export . You exported nif will be magically separated again.

ZOMG, it works. Thanks. Never would have figured out that one. :thumbsup: Edited June 26, 2011 by Nadimos

Well, it's not magic. If you are exporting to NIF, the NIF Scripts will separate objects based on material and texture properties because the Gamebryo engine will CTD on any NIF files that have multiple materials on a single NiTriStrip.

 

If you have 2 or more objects with the exact same material and texture path, they will not be separated during the export process...they will remain stuck together.

 

So basically, this process may be quick-n-easy for NIF exports but should not be considered a solution for other export processes.
