UV mapping not exported on blender

General Forums Blender and CG Discussions

When texturing a model on blender without UV unwrapping it (without using the UV Editor) the UV mapping data is not part of the data of the exported file, how come?

The BLEND file not suffering this problem, It saves the UV data and the Model loads nicely with it’s textures with no problems at all. But when the model is exported to other format (like: 3ds, dae and such) the output file is missing the UV data, why?

When trieng to load the exported data to XSI it loads without the textures and sometimes without the materials as well. When trieng to load the model in XNA i get this error:

Error 1 BasicMaterial has a texture, but the mesh “Sphere” has geometry that does not contain texture coordinates. C:\Users\hido\Documents\Visual Studio 2008\Projects\The Invaders\The Invaders\Content\models\earth.fbx The Invaders

Any help will be appriciated.

You need to UV unwrap the mesh first otherwise your object doesn’t have any UV co-ordinates to export.

But why?
I need only to Texure a Shpere with Earth texture and normal map!

I’m assuming you are mapping your texture to your object using some coordinate system (the Map Input tab) other than UV coordinates. The exporter only exports UV coordinates so without these (created when you unwrap your mesh in the UV image editor) any other application does not know how to apply your textures, only blender knows internally.
