Hi everyone, Not sure why but I am getting these weird screen effects after creating several decals, the screen effect moves with the sun angle (cause of shadows maybe?). I use shade-c by the way, maybe its cause of the shader I use for the decal? Here are some pics:   My code the spawn the decals:
PARTICLE* p = ent_decal(ent, _bmap, _size + random(_size_random), _rota + random(_rota_random));
p.lifespan = _time;
p.material = mtl_simpleTransparent;
set(p, TRANSLUCENT);
And here is the shader/fx file of the decal:
//------------------------------------------------------------------------------
//----- USER INPUT -------------------------------------------------------------
//------------------------------------------------------------------------------
//assign skins
#define SKIN_ALBEDO (skin1.xyz) //diffusemap
#define SKIN_ALPHA (skin1.w) //alphamap
#define SKIN_NORMAL (skin2.xyz) //normalmap
#define SKIN_GLOSS (skin2.w) //glossmap
//...
#define NORMALMAPPING //do normalmapping?
//#define GLOSSMAP //entity has glossmap?
#define ALPHA //entity has alphamap?
////#define TRANSPARENT //entity alpha should be interpreted as transparent/translucent?
//------------------------------------------------------------------------------
// ! END OF USER INPUT !
//------------------------------------------------------------------------------
#include <scHeaderObject>
//custom code goes here
#include <scObject>

Is creating them as soft_sprite / soft_particles as fix? Do you need to turn on forward rendering when using the standard particle/decal set?

Hi Malice tnx for replying. Cause of your reply I did some more tests and it only happens when I fire at a shade-c dynamic light while just standing behind its lightrange. The shade-c lights are valid targets in c_trace's. I quess it makes sense when I look at the light create code, just suprised they didn't mentionend this in the examples cause its so easy so overlook (this could have created some many bugs lol):
ENTITY* spotlight2 = sc_light_create(vector(-156,-82,800), 1000, vector(2000,512,0), SC_LIGHT_SPOT | SC_LIGHT_SHADOW);
spotlight2.pan = 0;
spotlight2.tilt = -43;
sc_light_update(spotlight2);
As you see there is an entity created to support the light. My quess is this entity is the cause the bug so I am going to try giving it some flag or otherwise give it a .group number. -edit, yes it works.

Since all lights will be a issue and the flag2 is pointless, I'd add flag2 to all lights and c_trace with ignore_flag2. It's a blanket solution and your going to end up using groups for selective ignoring not blank ignoring...
Ok
