Question: .obj import with muliple UV textures

Support Basics & Interface

Hi,
I have imported a mesh form an >ojj file that has more than 1 UV map associated with it. How can I get the multiple UV images to show on my model?
Blender 2.3

Thanks in advance

Hi,
This whole Blender import thing is just so complicated, maybe I’m doing something wrong. Is ther some import script or method that imports all the ojects with the UV’s and automaticaly assigns the textures, so I don’t have to re apply the maps for every part with a UV?

Thanks,
I did get the objects to separate but then they lost the UV’s.

Someone here made an importer that handles a bunch of formats, but it’s a .blend, and I can’t figure out how to use it.
any help?

What app are you importing from? Several apps can export OBJ.
What version of blender are you using?
Which script are you using? Be specific because there are OBJ import scripts that have been updated many times.
Which app did you use to apply the UV’s?

OK,
I’m using Wings3d for modeling and the internal autouv for creating the uv coords. I create the texture maps in psp and export the maps as .tga files. Then export my models as .obj files. they are fully texturd and mapped in 3d explorer and carrara studio, so I know they are good.
I’m using Blender 2.3 and importing with obj_io_modif228.py script.

You say you textured them in those other 2 apps or you tested the wings textures in them? When your first language is english the people who are likely to answer your questions best are usually not native english speakers.

Anyhow, that is the best script and you should have read this in the script itself:

IMPORTING:

If your OBJ model has uv mapping coordinates, and you want to use them <===== NOTE

in Blender, you can access them in two ways. The best way is through Blender’s

realtime UV coordinates which you enable simply by selecting the UV option in

the material edit window. This gives you an exact version of the uv coordinates.

An older method is to select the “stick” option in the material edit window. I

really don’t know why anyone would want to use this option since it cannot handle

seams and texture overlap, but I left it in just in case someone could use it for

something.

If your OBJ contains groups, once it has been imported, it may still appear

to lack any material indexes. If this happens, it can be remedied <=== NOTE

by going to the mesh editor window, clicking on the mesh selection button, and

reselecting the mesh you have just imported. You will now have as many

materials attached to your object as there are groups. You can then select

different groups by doing a material select when you are in edit mode.

Finally, you might have problems with certain parts of the object not displaying

after you go in and out of edit mode the first time. To fix this, simply go into

edit mode again, and select the “remove doubles” option.

As I know, Blender can’t handle more UVs on an object.
So you can’t import only one UV set…

You can make more UV-ed image in a material, but the UV coordinates will be same.
