Dosen't appear to do anything using DR 2.03...

[Sotha]

You are using an (very) outdated version of the script. Download the one in the linked thread and place it in the proper folder.

 

Okay, I downloaded the exporter from the OP (this one: http://forums.thedarkmod.com/topic/15026-dr-ase-blend-exporter/?p=318475) and now it works as advertized.

 

The vertex blending exporter I had, I think, was the one that comes with DR 2.0.2. Does the DR come bundled with the wrong exporter? Can someone confirm?

[Bikerdude]

Hmm, why is it working for you and not for me - I have to missing something obvious here....

 

I asked Greebo to adde dit to 2.02 onwards, its possible I gave him the link to an older version by mistake. When he resumes work on 2.03 I will ask him to insert the latest version.

 

[update] just tested with DR 181 and the export works fine, it appears that DR 203 breaks or dosent want to work with the script :-(

[Obsttorte]

The script that comes with DR is a wrong one. I've already reported this to greebo.

 

Something got mixed up there as I made several versions.

 

 

it appears that DR 203 breaks or dosent want to work with the script

Will test that once I find the time.

ta.

Well didnt have to use Blender, just created a single large patch, added some extra colums and rows of vertices, exported happy days.
