Collada collision detection

Hi everyone,
this is my first post here so dont punish me to much ;p.
First of all i use blender and the actual DTS exporter (0.964) for testing and the model (in my case a tunnel)
is exported well and also imported well inside T3D (art/interior), only the texture is the Torque Warning one
and will not be saved in a other texture after using the material editor, but this is a other case and i think it is the Bug that others already reported.
Now i used the Collada exporter from blender and it also exported well without any warning (same model with same hirachy),
but if i import it from the art/interior it crashes T3D. But when i delete all the collision meshes inside of Collision-1 and also the Empty/Dummy Collision-1 it is importing the model correctly and (what a wonder) i can also update the texture from the material editor, but the collision are now not working. When i dont use poly soup the player is running through the model of course without any collision (why should he? there are no collision mashes), but when i use poly soup he is hanging almost on all parts of the tunnel.
Any idea what i do wrong?
Thanks.

That could really help ... i will try it out later and let you know.
The model is loaded into T3D real small, almost impossible to see and it have to scalled up to 500 so that the player can move into the tunnel.

Thank you Logan, that was a point that i read on your Undercity Thread a few minutes ago.That could really help ... i will try it out later and let you know.

Is the problem with the material editor solved with Beta 3?
Or is there any workarround for now?

Right now tested and works like you said Logan.Is the problem with the material editor solved with Beta 3?

Wait, polysoup works with non-triangulated quads?

The polysoup also works with pentagons, hexagons......
It works with everything i've tested.

Yes,it works.The polysoup also works with pentagons, hexagons......

to export as triangulated quads.

Yes it works with all but even if not the Blender Collada Exporter have the optionto export as triangulated quads.

With that said the Undercity collada mesh uses polysoup and really doesnt have too many issues (there are a few but its doubtful you will notice them from a simple test). So just as long as you aren't exporting a thin "tube" like shape you should be ok for most collada useage. In most other cases, areas that stop the player can be easily fixed by an intelligent usage of quad shaped polygons (and no n-gons).
