Is there any way of being able to see the effect of a gel light in the preview, instead of tweaking a tiny amount and then rendering? The light has to be perfectly aligned with the grid object and doing it 'blind' is a nightmare. I'm thinking that numbers might be involved and I am horrendous with numbers. What I mean is, I suspect that with the light at a distance of --- away from the object along the z axis, the scale of the light's image would need to be --- and so on. I don't know, this is something I could do easily with a projector in real life, I'm sure, lol!
