Hi, it's me with my ent_decal problems again. So, basicly what I am trying to do is a bullet which simply makes a hole when it hits a wall. And I did it this way:
......
VECTOR trace_target;
vec_set(trace_target,vector(50,0,0));
vec_rotate(trace_target, me.pan);
vec_add(trace_target, me.x);
c_trace(me.x,trace_target, IGNORE_PASSABLE | USE_POLYGON | SCAN_TEXTURE );
PARTICLE* hole = ent_decal(you,bullethole,10,random(360));
.......
But the SCAN_TEXTURE flag causes me a lot of problems and when I remove it the decal doesn't appear : ( . So, can you tell me how to do the same thing but without using this flag. Thx : )

What problems does scan_texture cause? Because it REQUIRED to ent_decal to work.

When I use SCAN_TEXTURE the decal somehow takes the material from the model. This is how the decal Should look:  And this is what happens when it is put on a terrain with Multi-texture shader:  It has some kind of a black-white square frame. When the decal is on a Non-material entity this problem doesn't exist. Any ideas ?

Hmmm, it appears the shader is trying to multi-testure the decals...
Try changing your decals to be 32-bit TGA rather than BMP's.
OR
Try setting the decals TRANSLUCENT flag on. "set(hole, TRANSLUCENT);"
You may need to set its alpha up to 100 too.
OR
You may need to do both TGA and TRANSLUCENT...
If this doesnt help, I would take this issue to the SHADERS forum...

I just found this in the manual under ent_decal
Decals are rendered with the entity or block material and shader unless they have an own material. The decal texture can be accessed through entSkin1 in a shader. If the shader is not suited for a decal - f.i. when entSkin1 is used for a color mask on a multitexture shader, or when the alpha channel is not used for transparency - assign a decal material without a shader, such as mat_model or mat_terrain dependent on which object the decal is attached to.
So CODEWISE, I would try this...
...
c_trace(me.x,trace_target, IGNORE_PASSABLE | USE_POLYGON | SCAN_TEXTURE );
PARTICLE* hole = ent_decal(you,bullethole,10,random(360));
if(hit.texname) { hole.material = mat_model; }
else { hole.material = mat_terrain; }

So which one was it? The materials need setting (as in my last post)?

No, its necessary to my mine.
1> you have a shader that applies a lighting effect. decals inherit the light level.
2> model has a shader thet deforms its surface, decals will inherit the change.
See what I mean?
