Hi,

I am using 3DsMax and just realised a big difference between MR and VRAY. I typically use MR but a few days ago compairing lights I stumbled on something that really bothers me and I'm hoping someone will tell me I'm doing something wrong. Using a FreeLight and activating the Shape/Area Shadows, I always thought the light gets distributed from the shape as it does with a VRAY Light. But this isn't the case, is there some setting I'm missing???

Someone give me that golden answer.

Matt :wip:

Use mrportal light, but turn on "custom" in its paratemers to be self-illuminating.

Do you mean its light uneven distribution? It's just different, not worse. MR portal distribution is more scientifically correct.

For physicly correct light use a photometric light with an IES file loaded in the web distribution slot.
Your scene must be at the right scale tough.

IES files are free and are real world's light equivalent (neon, bulb, etc) in computers.

you can find them in many site like this one :
