How do you make collisions for large interior cells ?

Is 3dsmax software essential for collisions ? is there any method to create accurate collisions automatically without any manual editing ?

You can copy collisions into a nifscope. This is a copy of similar geometries with approximate dimensions from other nifs. To create good collisions with precise dimensions and geometry, you need 3ds 2013 -2014 with the bgs_nif_exporter tools installed (located in the tools folder in ck). Collisions are initially normal child meshes, hct converts them into rigs for parent meshes, elric converts collisions to fo4 format.

I might be lacking coffee, but why do you want to create collisions for interior cells?

Collisions in interior cells are done by creating collision geometry in the CK. You basically click the 'create collision cube' or choose the 'collision plane' icon, from the top row of icons. You can then edit it, size it, and place it. I would paste a screenshot.. but that's not allowed anymore.

So here's a youtube tutorial instead, the technique works 100% the same for fallout 4:

In order to facilitate better navigation for NPC's and players. In the old days we called it the 'caulk' process in mapping. Basically block out the entire map again with collision models so the engine had an easier time of it. Was especially important for the Doom3 engine which did per pixel collision.

 

A great example is the Dream Sequence maps in the main campaign where you're in Kellog's head. That map's filled with collision cubes to prevent players from running off the ledge. You can also add collision cubes that only work for NPC's, making sure they stay in one spot, or don't fall off ledges etc...

I know, just needed more coffee, and I was thinking of collision planes/cubes. The rest is done when building precombines/vis.

Wasn't it Unreal that you subtracted from the world, like a big block of clay and Halo you added to the world? I know Half Life you had to clip everything outside the cell to prevent memory leaks. I think it was Half Life. Getting old sucks! LOL
