Using very big models in wed

hello i have a big modelfile!
Its a bridge!
Small blocks,and so on!
How can i use this bridge correctly????
Because if i fit it to wed and compile, i cant stand over the model.
polygon,bbox doesnt function!!!!!!!!!
greetings ness

make mdl passable and use invisible WED blocks as floor

I can go trough WED Blocks!
How can i disable this passable flag of WED Blocks???

The blocks aren't passable. Do you have a player model with an action attached to it in the level? Otherwise, you are only seeing the level through a camera, which can pass through walls.

no model is loaded in WED his action is player_model!
No attaching!
