So, I’ve decided to take a better look at using a proper linear workflow within Mental Ray and part of that seems to be learning Global Illumination and Final Gather. These lightning systems have always seemed scary and complicated to me, but after some great tutorials\u00a0at Lester Banks.com <\/a>and Stuart Christensen<\/a>‘s\u00a0YouTube channel\u00a0I am starting to see the light \ud83d\ude42<\/em> I would also like to thank Brandon from Backwards8.com <\/a>for sitting\u00a0down with me the other day to explain some of the different GI and FG settings.<\/p>\n

\"Labatt<\/a>I dug up a scene I had modeled a few months back of my old apartment. This is lighting s a test to see how I would like to take the render further. The render itself is black and white and the few textures and colours in it were added in Photoshop. I should mention that I’m not using the mia_roundCorner node<\/em>. There are\u00a05 area lights\u00a0in the scene being controled by a\u00a0mia_portal_light<\/em>.\u00a0Right now the\u00a0large windows are emitting 1,000,000 photons per light <\/strong>and the smaller\u00a0windows are emitting 500,000<\/strong>.\u00a0The portal lights are all connected to the same mib_blackbody <\/em>node which is outputting a colour temperature of 5500K<\/em>. This is in an effort to simulate mid-day sun.\u00a0The render camera is set up so that the film back is the same ratio as the resolution gate (960×540 px)\u00a0and I added the lens shader mia_exposure_photographic <\/em>to even out the gamma. I am still getting a bit of blotchyness around the corners, but part of that is due to the area light samples being set at 16<\/strong>. Overall I am really happy with this as a test and I will keep posting updates as my work progresses. I’ve also done a small linear light test with\u00a0a beer can model and I will post that shot when I get off of work<\/del>. If you have any questions about settings or the process as a whole post a comment below or shoot me an email<\/a>.
