[SOLUTION] Remove duplicate materials from Rhino MTL files

[tom_holly]

I've uploaded a script to remove and sort the duplicate materials in MTL files when exporting OBJ files from Rhino 3D.

It works for Rhino 4. It may or may not work for other versions.

This is not fully tested, so use at your own risk. You may post any bugs to me on this thread.

Just updated the content on the website link to include instructions on exporting from Rhino.

Can you tell me what is it ? thank you a lot.

Hello,

You appear to be trying to process the OCS file, you should be processing the contents of the MTL file.

When you export an OBJ file from Rhino, it creates an MTL file which contains the list of materials. It is the contents of this file you paste and process.

If you have any problems, please let me know.

Cheers, Tom

Pardon me tacking on here but the link to the mod script doesnt seem to be working.
Can you re upload it somewhere please.
I recently bought Rhino and would like to try exporting to Octane.
thanks

Hi,

I just tried the link and it works fine for me.

Perhaps the site hosting it was down for a while?

Cheers, Tom

Thanks, i will try it.

Sorry to say every time I try the link lately and today I get 'could not connect to server' error.
Tried both IE and Opera. The google cache version is missing the code...
Any reason why you cant put it here on the forum? We would appreciate it.
Thanks

[pixelrush]

ok still not working I give up. I'll go through Blender...
