need help with collision model

[Techbot]

Hello,

I've just finished my refinery model for my server but I can't get the collision model right.

So here is the model:

the collision model looks like this:

now the problem is, that you cannot enter the building on the left (which is obvious of course) but if I use the normal one with smoothing etc it still looks like this in the modelviewer:

notice the diagonal line.

any idea how to fix this?

e.g.

this:

becomes this:

Try adding $concave into the phymodel commands

I wish it was that easy. I did that already

You're supposed to give each collision block a smoothing group of 1 and then give the whole thing a smoothing group of 1 after combining them into one whole mesh. The model needs to be convex as well, so I would build the collision out of cubes.

I don't know if I got it right though...

You want to make each wall of the box its own septate rectangular cube for one.

For the entrance of the building use something like this.

The red blocks represent individual rectangular boxes. With this set up you should get the desired collision.

It looks like you'er making the whole collision for the box out of one object and that's why its collapsing. Try to septate it out with individual cubes.

Hope this helps!

tired that and it gave me the autohull result aka this:

which sucks

Why don't you just split each structure in to separate models? It looks like there's three major pieces total which would work out as separate models just fine in my opinion. You could arrange the refinery as you see fit when you spawn all the pieces. It should also help greatly with managing the collision hull.

Unless, of course, there's some specific reason why you need it as one whole model.
