This might help http://docs.daz3d.com/doku.php/public/software/dazstudio/4/userguide/lighting/videos/lighting_editor/start

Basically it is just like a point light but you can adjust falloff and spread without adjusting the light intensity, where as the old Point light’s spread of light is dictated by the light intensity.

A realistic light’s intensity falls off as the square of the distance (if the distance from the light doubles, the intensity falls to a quarter, triples and it falls to a ninth). The linear light fades as the distance (so at double the distance the intensity falls to a half, at triple it falls to a third). And as noted you can actually set the distances at which the fade starts and completes. That makes linear lights totally unrealistic, but much better at lighting a scene - using the option to set the end distance also avoids calculating shadows when they will have no visible effect, which greatly speeds rendering in scenes with a lot of transparent and trans-mapped surfaces.

Thank you all for your help.

Unfortunately, 2 minutes of any tutorial video and my eyes start to cross! He is undoubtedly a very clever fellow but could he please slow down a bit (actually, no, a lot!) and wouldn’t it be lovely if I could read what he’s pointing at!

I really do need this in writing so that I can study it at my own leisure ... and speed.

And whilst I’m having a moan, why can’t I see what has gone before when I am writing my reply? No, scrub that. I’ve just seen what THREAD REVIEW is all about.

With the exception of the image map support (aka gel lighting) Linear Point Lights work just like Uber Point Lights.  I wrote a tutorial on Uber Point Lights that you can find on the old forums here -> http://forumarchive.daz3d.com/viewtopic.php?t=160239

Yes that is my fault as I haven’t completed the Text transcript yet. I will post here when it is done and i WILL try to get it finsihed as quick as I can. I have had a lot of life issues I have had to deal with over the last 4 months hence why this hasn’t been done before now.
