Hi... anyone who haveexperience withLightscape ? Let's share.
I guess my question would be...Why are you still using lightscape?

3DS Max since version 6 if I remember correctly. Plus Autodesk doesn't even support Lightscape anymore, that means no updates and no customer support and I'm guessing that with the slow switch to 64-bit, LS isn't might not work, but that's just a guess.

How about Radiance ? I have experienced Desktop Radiance but I found that it is not user friendly and full of bugs. Don't know how about the performance of the linux version.

Are you doing lighting simulations? By that I mean, are you trying to calculate precise lighting levels in architectural models using accuare IES lights and materials? If so, then Lightscape is a good solution.
On the other hand, if you are just doing design visualization simulations and would like to incorporate indirect illumination and GI, where the look of the piece is more important that perfectly accurate lighting, then your best bet is a newer rendering package such as Mental Ray or Vray. We use Vray in the Denver and Seattle offices and have had great success with it.

I have had some email exchanges with the guy over at Nextlimit about maxwell, and from what I have gathered it will render light in a physically accurate way but it does not take in to account photometric files. Which is pretty useless for a lighting designer.
I asked if there where plans to add the photometric functionality and they said they haven't thought about it but would bring it up with the other developers...so who knows...maybe some day.
and...I have played with the trail...and it's really slow....really slow. really.

The other thing it doesn't do that a photometric sim provides is accurate light readings from anywhere in the scene.
Vray has a similar rendering system. If you look up Progressive Path Tracing in the user manual or on the web, you'll see it. Of course, this doesn't add all the specular caustics and the like that Maxwel takes for granted, but it's something we can play with if needed.
