Model Collision

NotGodOKay · October 22, 2022

Non porn-question ahoy. I did a simple house model for testing purposes but couldn't get the collision to work. It infact crashes or freezes the game when going near the model ingame.

This is when the model didn't crash the game when it's loaded. It did load and let me approach it once but later it stopped the game when it loads all together.

A few months ago, I modeled some stone walls and had similar issues.

I took a look at your House. The collision geometry looked ok in blender and Nifscope, but when I put it in the CS and tried to preview, it locked up the CS. I then opened it again in Nifscope, and a second window with one of my wall pieces. The Collision Nodes were very different. You have a lot of extra data, and I seem to remember simplifying mine to get it working.

Can you give an example?

Не порно-вопрос ахой. Я сделал простую модель дома для целей тестирования, но не смог заставить столкновение работать. Он фактически вылетает или замораживает игру при приближении к модели в игре.

Это когда модель не сбила игру при загрузке. Он загрузился и позволил мне подойти к нему один раз, но позже он остановил игру, когда он загрузился все вместе.

There is such an option (a simple collision for a single house, this model should not be used to scale such houses, there will be low fps in the game if there are a lot of houses) I did not correct the normals on the mesh after export - laziness, additional groups are lost (shadows on the faces because 3ds max doesn't seem to support it).

I was unable to create an MOPP array, I do not remember how to do it correctly, so a simple collision image.jpeg.56836301a33050ffca73e3c2339f9703.jpeg

I was new at this so it was an issue to work with.

But thanks for fixing it. Was replicating the info of the original game files.

Melamkish · October 23, 2022

Just took a look at TDA’s fix, and it is almost identical to what I would do. So that is a good file to work from.

Let us know if you more questions.

I wanna put Quake 1 textures on my models but wasn't successful at not making the game crash all the time. Should I export from Blender or is there another way?

*fejeena* · November 14, 2022

??? tda2 posted a working nif that do not crash. You just change the texture path. And mybe rework the texture. Of course a dds file or it crashes. And don't forget the _n.dds.

NotGodOKay · November 15, 2022

Is the normal map really necessary? I've made them dds but it didn't work anyway.

*fejeena* · November 16, 2022

There are some nif that does not need a _dds. But the house should have one to create the 3D effect, the joints between the bricks. Or you have a smooth surface.

Yes xxxx.dds and xxxx_n.dds must be dds files.

I changed the textures like this

Spoiler

All vanilla textures . but UV Map slightly changed

NotGodOKay · November 16, 2022

Actually I worked on newer models which was interior parts with Quake 1 textures on them.

NotGodOKay · November 21, 2022

How do I get custom textures to work? What format must the dds files have?

Also how to make material effects on colliders? (Stone, wood, etc)

Как заставить пользовательские текстуры работать? Какой формат должны иметь файлы dds?

Также как производить материальное воздействие на коллайдеры? (Камень, дерево и т.д.)

dds (multiples of 16 - 16x16,32x32,...,512x512 etc), png seems to work too, but it's better not to risk it

In nifscope, you will find it yourself in the properties of the collision/

Or you can set it up in the blender 249b, if the convenience of the interface is important to you.

Also, all this can be configured in 3ds max, in the properties of the bhk modifier, but this can be found in the skyrim tutorials - the essence is the same.

=======================================

For Skyrim, it works through the ass, it's better to use a chunkmerger there and adjust manually later.

Textures dds name.dds name_n.dds or a glow texture name_g.dds

dds: DTX1 or DTX5 or A8R8G8B8

Most objects use DTX1

And endings

"_n"-suffix: Tangent-space normal-map

   "_g"-, "_glow"- or "_emit"-suffix: Glow-map
   "_hh"-suffix: Gloss-map for hair, no alpha
   "_hl"-suffix: Detail-map for hair, alpha is opacity

EDIT: Oops yes, forgot the dimensions

Yes 16x16 . . . 256x256 . . . 1024x1024

And you can use dimensions like 256x512 or 1024x512.

Depends on how your UV map is designed in the nif. Example: The Oblivion paitings stretch one side so they use 258x128 textures.

---------------------------------------------------------

The collisions setting in the nif files

To get the right sound when you hit an object you change the Material in the nif collision

But first you set in bhkRigidBody if it is static or moveable (misc mesh)

OL_static

OL_clutter of items like books, plates, cups, ingredients,...

OL_weapon

OL_PROJECTILE

Spoiler

To change it you double click the OL_ name and you can open a list

And to get the right foot sound

OL_TERRAIN it is used for big rocks

Spoiler

And in the bhkRigidBody you must set his.

Spoiler

In vanilla oblivion are nif with wrong settings, e.g. the Paint brush. If you drop them from inventory they will hang in the air because the settings are like static objects.

-------------------------------------------

And you set the material in the bhkMoppBvTreeShape, bhkConvexVerticesShape, bhkCapsuleShape, bhkBoxShape, bhkListShape, . . . or whatever you use

HAV_MAT_STONE

HAV_MAT_METAL

HAV_MAT_WOOD

HAV_MAT_CLOTH

HAV_MAT_ORGANIC

... and many more double click the HAV_ name and can open a list

Spoiler

-----------------------------------

A house nif (interior and exterior) is set to

OL_STATIC

and material to

HAV_MAT_STONE or a wooden stable to HAV_MAT_WOOD

I might have figured out what went wrong with the Quake models. I've made a new nif out of the one I've gott from tda2 and it worked as long as I used "Save As..." instead of duplicating the file from desktop but I haven't tested it yet. Should do that today.

UPDATE

I got 1 model exported from Blender working with the game's original textures so I'm assuming the Nifskope obj importer causes the game to not handle it well.

Smart people explained to me how to make a MOPP collision (composite collision that does not slow down the game - you can make architecture out of it). This is a 3dsmax plugin with version 4.0 nif

For example, I rigged a render from the game and edited it in 3dsmax and made a collision directly from this model (many meshes) it works fine
