how do you decide where to put your light source?
i usually try to make it match the render and place it in an already light place of my sig

[hellraid]

I place it where I can see where the light is coming from and try to keep it in mind to go with the flow

[murch]

yeah i normally use stocks not renders, so i place it wherever the stocks lightsource is.

[Thrasher]

it depends all on the stock your using :) you can see on it wherefrom it comes from :D

[Ralic]

I agree with everyone, wherever the light is comming from in the stock.
But tbh, I never do it right...
