yojeff Posted March 26, 2023 Share Posted March 26, 2023 How does the collision works for fondation pieces in building mode? For a floor decoration, I understand that the decoration "drops" to the ground (of the world map). If you build it, and try to put a new one, the new one "collides" with the first, so it goes on top. (Well, I guess it's not really the collision? If it was, we could put a chair under a table. So it's more a bounding box, a min max of x, y and z?) How does it works for a fondation piece? It can go through the ground. Are there two collisions in the nif (one for the top, one for the sides), and the second is deactivated during building, or is it a different node in the nif? Thanks!

South8028 Posted March 27, 2023 Share Posted March 27, 2023 collision is just a regular mesh. For the havok engine, this mesh is the physical interaction boundary. You can easily put a chair under the table if the collision literally repeats the shapes of the objects. But most of the vanilla collisions in the game are primitives. They are simplified as much as possible to reduce the load on physics. Therefore, many tables have a collision in the form of a cube, or a cylinder, or another primitive. You can't push another primitive into a primitive. fo4 was created in 15 for medium PCs. Therefore, Bethesda tried to simplify the physics as much as possible.

yojeff Posted March 27, 2023 Author Share Posted March 27, 2023 Yes. You can open a nif in Nifskope, and there is a toggle to show the collision. I'm wondering how it works in building mode. The furnitures stay -on- the ground, but fondations can go -through- the ground. There is also the water pump, where the concrete base go -through- the ground.

yojeff Posted March 27, 2023 Author Share Posted March 27, 2023 Thanks! I'll have a look! Link to comment Share on other sites More sharing options...
RaidersClamoring Posted March 28, 2023 Share Posted March 28, 2023 It comes down to snap-points placed in NifSkope which kinggath explains expertly in these here video films: Link to comment Share on other sites More sharing options...
