Converting to morph destroy uv maps

Hello,

 

I have made an object in Blender uv mapped, when I import it into ac using collada the textures are fine, but when I convert the object to morph the uv mapping is lost.

 

Am I doing something wrong or is there a way to avoid this?

 

Object right after import as collada:

Object after converting it to morph:

I'm hoping there is an answer to this - I have the same problem importing sketchup objects.

I do fear that this is not possible at the moment.

Doing UVs (somewhat) correctly can only be achieved in GDL, meaning in an object. As soon you convert that to a morph it won't work.

I found a "workaround", the main reason for converting a imported model into morph is to be able to hide the unnecessary vertices without dealing with diving into the gdl code as @runxel suggested. Althought it could be great, dealing with texture mapping in the gdl code is a nightmare (sorry for the harsh word).

 

The workaround is to install the Archicad goodies specifically the 3ds import addon, with it you can have a much cleaner mesh representation in the elevations without the messy mesh looking.

 

Of course if you convert it to morph, the uv's will get lost

 

Collada import on the left and 3ds on the right in elevation view:

How are you exporting to 3ds?

 

And when you import into AC the UVs are maintained?

One blender developer has made a 3ds import/export addon.

Yes, so far the object comes into ac as it was in blender, but if you convert it as morph, then the uv maps are destroyed anyway.

Thanks but I can't get the script to work 😳

 

Which file do I need?  Tried all 3 and combinations of but after attempted install the plugin doesn't appear in the list

You have to download the whole folder from here:
https://github.com/blender/blender-addons-contrib

After downloaded unzip and navigate until you see this:

Then drag that folder into your Blender script addons in the AppData, something like this:

And after that launch Blender and it should show in your addons, enable it and ready to go

Hope it helps 🙂
