hi ,

today i install MentalRay and ive made a test-scene to test GI , the only problem is Gi doesnt work , i used this tutorial to make the scene. .

I have also read the maya help but i cant find the problem.

he gives an error if i render :

RC 0.0 warn 082016: lens shader runs in scanline mode, it must not modify the origin or direction of the ray
If someone want to see my testscene to determine wat the problem is he can download it here :

Hey, I just wanted to let you know that I got your scene and will check it out today and get back to you either today or over the weekend.

Hi Kaas,

It's the Photon Energy of your light that's the problem! Because 'Physical' is turned on, you need to increase the amount of Photon Energy by quite a lot.

Setting the Photon Energy to 800 000 makes the GI show up. It was just too dark to notice!
