Well, it exported with open collada. I just dont see anything in in PCS2 after loading.
Here are the Max, obj and dae files(depending on your program).
I will now try to import the box i downloaded and slapping textures on it.
Edit: I downloaded a PCS 2.1 alpha I found. It is not loading pof files. Stops 3/4 way through

The conversion proces with Max goes like this:
name your box "detail0" without the quotes. Move the pivot point to the center of the cube, then make sure the cube is at 0,0,0.
Create a helper (dummy), name it "center_detail0" and move it to 0,0,0.
Reset X-form then export.
Load it up in PCS2 and save it to pof.
Thank you. I shall try this. Lol, I sent you a PM asking this before I saw the thread.
Edit:I have Max 2012 and PCS 2 shows nothing.
Then you're out of luck, i'm afraid.
All Max versions past 2011 are incompatible with the OpenCollada exporter - which btw, pisses me off to no end.
The build-in Collada Exporter exports, on a good day, the model ( you see it in PCS2), but it lacks UV/ Texture coordinates*.
You could get Max 2011/ 2010 but that be a expensive route. Alternatively, export the model to either .obj or .3ds open it in Blender and export it from there to .dae.
*actually The UVs are there, it seems that PCS2 can't "read" them.
