I have a model which has 3 UV maps which I need to export to another 3d program(modo) but am unsure how to go about it. I need to export as a .obj file but do not think this can handle multiple uv's. Is there a way to merge these maps into 1 map? Please be gentle as I am a beginner with blender and still feeling my way.


Cheers Damo

    $\begingroup$ Try exporting to FBX file format instead, I think it supports multiple UV maps per mesh. $\endgroup$ Mar 15 '17 at 2:44

    $\begingroup$ I'm pretty sure .obj supports multiple maps, but I know for sure .fbx does. It may be a problem with the importer, not the exporter. $\endgroup$

    $\begingroup$ Create a new Image and Bake the textures. $\endgroup$ Aug 18 '17 at 1:24

Blender has an add-on for Combining multiple UV maps into one. Texture Atlas. TextureAtlas addon for unwrapping and baking of Shadowmaps/LightMaps of entire scene

The addon Documentation has some tutorial Videos on how to do that. https://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/UV/TextureAtlas

I use 'bake' to turn everything into a single texture.

First you have to go to 'UV Maps' and create a new UV. I used the name 'UVBake', but it can be anything.
enter image description here

Now select the entire mesh, press the 'U' and 'Unwrap' key.

Now in the 'UV Image editor' create a new image. enter image description here

Now in the rendering panel, go to 'Bake' and select 'Textures'. enter image description here

Click on 'Bake' and you will get all the textures in a single image. Save it. enter image description here

Now you can delete all the materials that belonged to your object, and create a new material. enter image description here enter image description here

Create a new texture and select the one you made. //////////////////// enter image description here

If you did everything right, you'll get the same result in just a single texture. enter image description here

Now simply export your object the way you prefer.
