Two questions on Glow

Hello,

Two quick questions on glow, if I may..

1. I have looked at llSetPrimitiveParams and cannot find the Glow param, does it exist?

2. If I apply a texture to a prim, then set Glow to any value other than zero, and then set the prim to full alpha (using llSetAlpha), it does not go fully transparent (almost, but not quite), you can still make out the texture as it is still glowing! Is this normal?

Vi

1. Yes.
[PRIM_GLOW, integer face, float intensity]

2. Yes.
Set glow to 0.0 when you set alpha.
