Symetry

[Gniarf]

Hi all,

I'm trying to make a mod that allows to dual wield most weapons. But there is no 3d model for left handed vampguns, for example.
So I'd like to know if there is a function to flip a model left/right. Or maybe stretch it in one direction with a negative factor.

u could mirror it if u could get the model into 3ds max or somethin

Funny that you say that exacly when I'm trying the Blender pkmdl importers, who ofc, do not work. Well actually they work for some models, at least I saw the tank and the dual heavy mg, but they fail for the vampgun and the bar1918.

Yipee, I finally found a way:
1-In [name of the weapon].CWeapon you should have something like:

o.Scale = 0.5 
o.Pos = Vector:New(0.4,-0.5,-3)
o.Ang = Vector:New(0.15,0.2,0)

well turn

o.Scale = a
o.Pos = Vector:New(b, c, d)
o.Ang = Vector:New(e, f, g)

into

o.Scale = -a
o.Pos = Vector:New(-b, c, d)
o.Ang = Vector:New(e+3.14, -f, g)

(yumm, dual vampguns, vamp shotgun+RL, dual shovels...Here I come!)

Symmetry problem - round 2: whenever I set a negative scale in a .CWeapon file the weapon turns black as if there were no light at all on it.
I looked through the .lua&.CWeapon files, but I didn't find the definition of that light (I used the vampgun as a test subject).

So, does anyone know how to restore the weapons to their normal looks?
Or at least can someone explain me why the weapons are turning black?

sounds like it inverts the vertex normals along with the model

1-Thanks.
2-I'm working on it, but I've got a busy RL now.
3-...2 sided texture rendering should do it, right?

Not even a reference to some light object(s)?

[Gniarf]

Save for the muzzle flash and various firing fx, yes - no lights at all.

Ok, I have a few questions:
1-What's the diffrence between 3d mesh and 3d model?
2-What happens if I negate vertex uv coordinates (or rather only u cooridnates)?
