Grenade Area of Effect

Do you measure grenade area of effect (such as alchemist’s fire) the way you measure light source radius or the way you measure spell area of effect?

Spell I believe.
So a 1-yard area of effect is 1 hex, 2 yards is a hex and surrounding, etc.

Light sources, if I remember off the top of my head correctly, are larger as the point-source is defined as the hex it's in so you get a hex 'for free' in a way. Thus the 1-yard light source area (source hex, and surrounding hexes) is equivalent to the grenade/spell's 2-yard area.

In retrospect, I kinda wish the two were standardized so that both followed the same rules but I think there are some spells that use the light source method? IDK, this is why we love gurps :D

That's a good way to conceptualize light source radius. Thanks.

I had the same question, and posted Kromm's answer here for posterity.

It's as Polkageist describes.
