Rocket not getting launched correctly from a tank.it does have a negative degree

[i.Q]

As its not that easy to describe the problem, here a few small videos (< 300kb), to see what its about.

problem:
ITOW
the rocket doesnt get launched the pointed area (by the cursor), but has a negative / to the ground aiming degree.

We do have this problem with most rockets, just these three work and we cant figure out the reason for it.
works:
AT 5
ATGM AT 10
9M113

these are the three working ones !
(a few values edited out like names and sounds...)
can one see / know the reason that those three do work and the rest not ?

ITOW's ammo config

Code: [Select]

class WGL_BGM71A: WGL_ATGM
{
hit=400; indirectHit=480;
model="\wgl_veh\tow\wgl_towproxy2.p3d";

};
excel based overview

it could be the config value: model, as except for one exception the three working one do have the BIS TOW model:

Code: [Select]

model="TOW";
for all values the same:

Code: [Select]

simulationStep=0.01;
thanks for your suggestions !

I assume your custom missile models have correct geometry LOD...?
Lack of one will cause trouble, but not seen it do that though...

Have you tried to config test tanks to use some of those working missiles to see whether they work with the tank or not?
If you haven't, try doing that, it may lead you closer to the problem...

If the otherwise working missiles won't work with the ITOW and the tank launching it then it's the tank model (or maybe config) that is somehow fubar...

Its probably your models:
- Make sure the missile models have proper named selections
- Make sure the missile models have proper gemoetry LODs and mass
- Make sure the vehicle models' muzzle start/end positions are facing the right direction, and also that the gunner view is in the right spot

If you can't confirm the problem, try this to identify the source of the problem:
- Try using BIS models with your config settings
- Try using the weapons from different vehicles

The first thing I would suggest checking if you confirmed that the models are the problem is to check the mass of the missile. If its too heavy you might need to either decrease the mass or increase its thrust. Thrust will effect the missile's trajectory.

[i.Q]

ok it seems to be about the unit firing the rockets !

t55 works fine with any type of rocket
whereas
with t80 they just drop like shit  

could it be that there is relation to the aiming point / why is the aimpoint fixed to some and 'dynamic' / 'moving' on others ?

t80_fixed
t55_dyn
itow_fixed
at5_dyn

 :crazy:

thanks for your help so for HateR_Kint and Kyle Sarnik !  

[Kyle Sarnik]

In that case, it probably has something to do with the memory LOD selections for the vehicle models, make sure they have proper muzzle start and end selections for rockets/missiles.
