All ONWC files are 0 byte files. That means that Oni takes the information out of the ONWC files of level 0. Below is an example of an ONWC file of level 0. The first pic shows the beginning of this file. The second pic the end of it.


Unless specified otherwise, the coordinates are relative to the weapon's mesh (x = forwards, y = left, z = up).

0x138 float 00 00 61 44 900.000000 maximal shooting distance; if target is further than max.shoot.dist then A.I. ceases fire and moves towards the target until at least max.shoot.dis. is achieved;

Transform matrix
Probably defines the orientation, scaling and position of the firing spread. It doesn't appear to be used.

0x158 to 0x1D7 - Secondary firing mode

The only original weapon for which these fields are not all zero is w11_ba1.

They are the exact counterparts of the fields at 0xD8 - 0x157.


0x1D8 to 0x6D7 - Weapon particle array

Every ONWC has 16 particle slots (80 = 0x50 bytes each.)

The number of slots actually used by the weapon is specified at 0xCA.

Offsets are relative to the beginning of a slot.

Glow textures
They're applied to the lower face of the M3GM's bounding box. The factors above are the ratio between the x/z extent of that face and the half-length/width of the glow textures. So if both factors are 0.5, the glow textures fit the bounding box exactly.
Pickup handle
The tolerance is hardcoded. The offsets are not relative to the weapon's axes, but to the world axes (!).
This is a rather nasty "feature" (actually, the offsets should be relative to the weapon's orientation)
The way it's now, the pickup volume of a WMC is not necessarily next to the handle. That's why it's hard to pick up.
