Export Mods from TF2 in TF is possible ?

It's possible to a certain degree but that would require a lot of manual work, as you would have to extract the model tree from the mdl and move the information to grp and msh files.

Open and compare the .mdl .grp .msh and .mtl files of a TPF2 and a TPF mod, then you can see where the difference is and what you need to move and rewrite where. It may also be impossible to downgrade all mods due to certain functions that were not available for TPF1.

Which mod do you want to downgrade?

You have to compare the model structure in TF1 and TF2 to determine the differences. Some examples:

• The material references lists have to be in the msh-files. There have to be material configs to cascade the actual selected materials from the mdls over grps to mshs.
• The animations are embedded in the msh-files or group files. There have to be event lists to cascade the event triggers down to the mshs or groups.
• Some Metadata in mdls changed, like speed.
• Repaints require direct access to the msh to add in materials or have to use a mod util script like the one from Merk
• Script API has some changes, thus there might be some rescripting needed.
