IES light weirdness

[thomas]

The LightWave manual is pretty sparse when it comes to IES lights, so I had to explore. It turns out that funny things happen when you change the light size, both in LW and in Kray.

Check it out for yourself! Does anyone have any clue as to why this happens - and is it a bug or a feature?

Cheers,

I don't think IES lights are meant to be scaled. In Kray I can see what's happening - as the size increases the distance between two sample points increases and so it appears like you have multiple lights instead of one.

Me too. I never rescale IES (becouse for what?) there is ifo abaut power light etc. If effect on the wall is not good I change IES or I move it. You can use small trick: just move IES a bit farder from the wall (i know :real hallogen is in another place - closer wall, but people do that).
