For a project of mine i converted a per-pixel Spotlight shader to 3dgs .fx and at this process i think i found a bug at vecLightDir.
light1.dir = float3(vecLightDir[0].x, vecLightDir[0].y, vecLightDir[0].z);
At this line of my .fx file i tried every combination that could be, for a possible difference at 3dgs and hlsl vector. (***.X,***.Y,***.Z) (***.X,***.Z,***.Y) (***.Y,***.X,***.Z) (***.Z,***.X,***.Y) (***.Y,***.Z,***.X) (***.Z,***.Y,***.X) But at evry of them i encountered wrong results. Because of that i added these lines to the action of the shadered model at my script:
while(me!=NULL)
{
if(car != NULL)
{
vec_set(temp,vector(1,0,0));
vec_rotate(temp,car.pan);
vec_normalize(temp,1);
my.skill41 = floatv(temp.x);
my.skill42 = floatv(temp.y);
my.skill43 = floatv(temp.z);
my.skill44 = floatv(0.8);
}
wait(1);
}
And changed the line at my .fx file like this:
light1.dir = float3(vecSkill41.x, vecSkill41.z, vecSkill41.y);
And the shader gave the correct results. Also changing vecSkill41.x to vecLightDir[0].x and vecSkill41.z to vecLightDir[0].y
light1.dir = float3(vecLightDir[0].x, vecLightDir[0].y, vecSkill41.y);
doesn't disrupt the correct render. It seems there is something wrong with vecLightDir[0].z ...Wrong Result SS  Right Result SS  PS: I use version 7.70...

full shader code versen daha iyi olurdu.
bu arada düzgün newton araba yapabildiysen VET e iletirsen sevinirim.

vecLightDir i kullandigm tek satir o, o yüzden bu sekilde açikladim. Araba konusunda da araci yaptim ama biraz sIkIntIlI hala, çabuk kontrolu kaybedip spin atio bir de kasa ile tekerlekler ayni materiala sahip. Biraz kodu düzenliyim VET'e iletirim source u...

daha bi ton shader yazildi (ki hepsi lightdir veya lightpos kullanIyor illaki) ve bende ufak denemelerimde pek bir problemle karsilasmadim(herne kadar dircetional light kullanmamis olsamda).
Buyuk ihtimal zaten yapmissindir ama SPOTLIGT flagi acik degilse o isigin vecLigtDir inin bütün ögeleri 0 oluyor.
vecLightDir ile bi kac ufak deneme yapicam simdi.

yok yok hersey dogru yukarda da belirttim zaten tek sorun vecLightDir[...].Z de. X ve Y de bir sorun yok. Spotlight flaglari de var. %95 ihtimalle sorun vecLightDir[...].Z de, her türlü denemeyi yaptim ben.
