Hi

I wonder what is the pros and cons using emissive vs. octane lights?

When should one use the diffent way of lightning? - or combine them?

Thanks

somebody else have made a comparsion of speed in this order (don't remember where I read it)

fastest : daylight, then HDRI, Lights, and finaly emissive material are the slowest

But you can make a fake sun and combine it with HDRI:

Just place this light far away from your object then increase power and efficiency and decrease size to get more sharp shadows.

Hi

So it's primarily time.

Thanks to you both.

Actually there is one reason I would suggest using emissive materials over a light, and that is because you can change/alter the lights from the material editor. Normally this wont change much but I worked on a project where I needed hundreds of lights, some unique, and adjusting them was a huge PITA (because you can't edit multiple lights simultaneously, assuming you're using the 3DS Max plugin?)
