Default AC3D exporter.tcl script HELP

Hi, i have to batch convert many objects from COLLADA format to another format.
Luckily i found this script on this forum to do this:

http://www.inivis.com/forum/showthread.php?t=4180

this script works fine on small files. they load fine and export correctly.
however in some cases , where files are large and complicated , they do not load at all, and then the exporter exports an empty file.

I can load and export these same files manually and they work fine, so the issue is not the importer plugin itself, but this script.

Is there any limitation of TCL / ACD3 scripting i should be aware of? any chance to debug this behavior to find the source of the problem?


thank you very much.

I can't think how larger file would be any different. You could try pausing/syncing before calling the export but this should happen naturally anyway with the threading that is used.

Default Re: AC3D exporter.tcl script HELP

Hi Andy, thank you very much for your reply. Actually i did further testing today and found out that the COLLADA export fails with some DAE files. No clue why. The COLLADA import works fine, but when its time to export to COLLADA both the script method and manual method FAILS. You may be asking "why the hell do you import COLLADA and export COLLADA without doing any processing?" actually i do this to "normalize" COLLADA files. AC3D renames materials in a way i find useful , and later i process this AC3D created COLLADA files with some scripts.

The error im getting is this:

Default Re: AC3D exporter.tcl script HELP

Just tried importing/exporting the stadium model with AC3D 6.8.14 and then reloading the output and it was fine.

My test was under Windows. I see you are using the Linux version of AC3D - have you tried using the other AC3D binary which is statically linked?

Default Re: AC3D exporter.tcl script HELP

hi Andy, thank you for your reply.
You are correct im using Linux. I tested both AC3D and AC3DS binarys executed directly and the both fail.
I will try on a Windows version either over WINE or a VIRTUAL MACHINE. thank you.
