Object lights like these can be created using the glow (lume) shader and final gather.

Deetee, I'm trying to convert some brazil car paint materials over to MR. I will post them when they are complete.

Also, here's a link to some more MR materials. They are listed in the "downloads" section.

I cant find the Mental ray Connection rollout. Where is it exactly? Refering to step 5 in the 3dluvr tut. "Faking SSS with Mental Ray ".

Im not an expert on this, byt i think it means your model is not complex enough for the amount of photons seleceted to be used. Try making the model more complex, and see if it will work then

aljoker: We don't need all your 100 errors... just one of them is enough, So please edite your post with just one of the errors.
This thread is very useful for all of maxers... thanks for understanding.

To solve this problem you should decrease the number of photons.
because it is very high for this small scene...
Or create a great sphere beside your scene that you want to render (out of camera view).
This error will happen most of the time so you can solve them with above ways...

aljoker,

The two HDRI files are available on the first page of this thread (if you want them). There's one small blurred HDRI that you should use for a light source (place it in the map slot for the skylight). Then a larger non-blurred HDRI file is used for the environment.

Also, on page two of this thread (second post) is an example scene using those HDRI's. You can download it and get a visual reference for placement of the HDRI's if needed.

In summary,

Small Blurred HDRI = Skylight map
Larger non-blurred HDRI = Environment map

Important:
Final Gather MUST be enabled in order for HDRI lighting to work within Mental Ray. This will also increase your render times.


Hope that helps.

Rexxenexx,

It's at the very bottom of the material tree:

You may need to go to the Customize, preferences, then go to the Mental Ray tab and turn on the button to enable mental ray extensions. This will allow you to see the Mental Ray connections tab.

Just to let you all know, this thread has answered hours of questions in under minuets. I have been stumbling through the help files in max 6 and cannot even find the words SSS. And also a big thanks to all who have shared files and spent there own time finding out all the settings and answers.
