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).

Crosshair

Default crosshair appears where the laser sight hits environment, corpses, etc

Locked crosshair appears when the laser sight hits characters (including the shooter)

"Tunnel" is used by w8_mbo as a complement to the crosshair

w2_sap, w5_sbg, w7_scc and w9_scr use it with no crosshair

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.

That's what defines orientation, stretching, etc.

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.
