Thanks for answer.
Yes, despite this crash, the editor automatically saves the project in a .$$m and a .$$w which work perfectly in wed, except for the actions which are not attached to the .mdl. (which is probably the cause of the crash).

yes, the crash can occur because if you use my editor the attached action scripts are not found.
if you check the $$m file, check a model that should have an action, its name should be saved under it.
but I checked it only with my own levels, so have no real experience with such cases like yours.

and another thing, if you use my editor, it writes some skills into the $$m and always uses the extended model property format. it can cause problems. in Emre's script it is examined whether to use the simple or extended saving of model properties, and does not add those "fictious" data I use.

I just checked the .$$m file, was interesting, here is an example



And it's the same for every MDL, so I think actions are lost. Don't want to bother more so ok for fictious data and thanks again.

after action there are 20 skills in 1 line, I store there bounding box size and some other entity properties used by my editor.

in the next line there are flags.

the last ndef as I remember is material.

the most perfect solution you could get is to integrate Emre's (or my) script into you script, in this case actions would work too. if I have time I'll try to convert my script to include easily, nothing magical inside.

Ok for the informations.
I tried to integrate since beginning but I get some errors, I must be too bad for make it work correctly but np l:
