I've managed to do as you sergested, and the new directory seems to be coming up with everything to do with Prall. Still no luck getting the physics model to export.
Infact I've taken a step back now, lost the texture.
Are the orange box tf2 studiomdl.exe and vtex.exe ok to use? or should I just stick with the HL2 ones and somehow move the model and texture over afterwards (how easy is it to move a prop from one game to another?)
I'm packing this in for the day, just going round in circles getting very frustrated.
I dont understand why the reference model will export but not the physics model. I've made a low poly physics box as like I've said, its insainly high poly count. I can't see anything wrong with the physics box but I cant think of much else, Prall is able to export the "reference" model so I dont see why it wouldn't be able to export the "physics", even with that command line space issue surely it wouldnt work atall if it was the problem.
Sorry to prattle on here, reserching a solution to this is proving pretty fruitless atm.
I might try exporting the reference layer as the physics as well, just incase it is something to do with the low poly physics box. I at least know that layer reference can escape maya

but id rather not confine all the props i make to a map skybox.
Also found there was an updated version of Prall (bringing it to 2.6) im going to try get that working tomorrow, my attemts today haven't had much success.
Why can't this all be like playing with crayons

or carboard boxes and sticky tape
