Hi,
in my little project, if I put one or more lights (LightCone, LightSqr, etc) I found that some part of the screen has no light and the other part yes.
It's a bug? or I did some wrong? In the picture is easy to see the issue.

void Render()
{
switch(Renderer())
{
case RM_SHD_MAP:
case RM_SOLID :
case RM_SOLID_M:
plat.draw(MatrixIdentity); // render terrain
for (int i=0; i<MAX_BOLES; i++) {
esf[i].draw(MatrixIdentity);
}
break;
case RM_LIGHT:
LightCone(120, Vec(30, 20, 0), Vec(-1,-1,-.5), Vec(.5,.5,1)).add();
break;
}
}[/     font]

Thanks in advance.

Try maybe to normalize direction !Vec()

Hi,
I post another issue about the lights. I noticed that if I move very little the camera the specular light level can be quite different, more than I would expect. Why?
    versus    

Thanks very much.

maybe you need to enable D.hpRt(true)

Thanks to answer my questions like near the speed of light.
The LightCone... now functions ok.
About my second issue, i am working with hpRt(true). My card is an a nvidia 7900 gs. It seems that there is no difference with hpRt true or to false in my application.
Thanks.

then it's possible that your card doesn't support hprt
