Created objects don't reflect lights / shadows

[ArranTuna]

Describe the bug
Created objects (as maps) don't reflect objects light as world objects do, here go some examples:

Vehicle light in a world object:

Vehicle light in a created object:

Object (that's also created; it proves that the problem is with the object which should reflect the light, not the vehicle/object that produce the light) light in a world object:

Object light in a created object:

@ccw808 made the following comment:

As custom objects are movable, they seem to be treated like peds and vehicles. i.e. No projected textures such as headlight beams, blob and square shadows, blood etc.

Followed by a later comment:

Should be possible, I'll look into it soon.

Problems might be:

1. GTA buildings only have z rotation (no x/y axis tilting), so the shadow/light effect may not work correctly for MTA objects which have x/y rotations.
2. Performance - Maybe only do effect if fx quality is not low, or add an option in the video tab.

i made an investigation and i found that function:
CShadows::StoreShadowToBeRendered(uchar,RwTexture *,CVector *,float,float,float,float,short,uchar,uchar,uchar,float,bool,float,CRealTimeShadow *,bool)
offset 0x707390

Last argument is bDrawOnBuildings and almost all time is 0 except for vehicles, where is set 1 is you're drive ( but this also not casting shadows ).
i tried change this byte to 1 while calling function

MemSet((void*)0x7081A4, 0x1, 1);
MemSet((void*)0x536241, 0x1, 1);
MemSet((void*)0x707EBD, 0x1, 1);

but still ped/vehicle shadows not working on object created by createObject ( i tested with rotation x,y,z = 0 )

Performance - Maybe only do effect if fx quality is not low, or add an option in the video tab.
there is condition in this function if ( CShadows::ShadowsStoredToBeRendered < 48u ) so you can't draw over 48 shadows

Look at 0x70ACB2. It explicitly selects buildings to draw shadows on.

I think I just found another problem that may be related to this.

The rain also doesn't collide with any object created by the createObject function.

To reproduce:

start the runcode resource
/srun setRainLevel(3)
under a normal GTA object, you will not see the rain.
under an object placed by map editor or createObject function, the rain will be there.

Maybe this is also related to the camera clipping when we are inside vehicles (#1921), and deserves a little more attention?

Also, I already tried to flip all the faces of the object to see if it's the root problem but had the same results.

The rain also doesn't collide with any object created by the createObject function.

That's because GTASA uses CULL zones to disable rain on certain parts of the map #1192

[BenhurPaz]

is there any way to fix this problem?

It might be related to some flags, I just noticed not all the world objects will have 2dfx light cast on.
