manta Posted July 5, 2007 Share Posted July 5, 2007 Hello MR experts, working on an old scene originally done with Vray, taking MR 3.5 for a spin, really happy with the way its comming out but reached a snag, the splochiness on the ceiling and floor, don't know why its so apparent in those two places, I've tried raising the final gather to high, and it does no good, I'm using MR sun and sky, two directional lights, and one omni, I think the problem is comming from the sun...any ideas, I'll post my settings as soon as I get a chance...thanx Link to comment Share on other sites More sharing options...
manta Posted July 5, 2007 Author Share Posted July 5, 2007 Ok here are my settings, keep in mind I have changed alot of them with no real change in the problem, which is weird in itself... Link to comment Share on other sites More sharing options...
Justin Hunt Posted July 5, 2007 Share Posted July 5, 2007 The photon sampling radius is too small, it should be relative to the size of the room. create a sphere that just encloses the room, read off the radius. This is the starting point for the photon sampling radius. (Remeamber to delete the sphere;) ) Why is the multipier set to 100? Use exsposure control to brighten the scene. If you are going the photon/fg route, start off without FG until you get a decent, smooth Photon result then turn on FG. Use Draft as a start. Can you post the FG settings? Personally I would go the FG/ AO route. Also turn off the directional lights and the omni. Set the photon radius for the sun to just fit the scene or even just the window openings. The suns shadow sampling is too low (ie grainy). As a side note make sure the walls, floor and ceiling have thickness. Photons hate single sided surfaces. As a fail safe enclose the room in a shelled box with holes for the windows. JHV JHV Link to comment Share on other sites More sharing options...
manta Posted July 5, 2007 Author Share Posted July 5, 2007 Thanx for your help guys, I'm not sure what the problem was, or how it corrected itself, but it did, the reason I had all the settings so high was to see which one would affect the splotchiness, but none of them corrected it no matter how high or low they were, really strange, but anyway here it is so far, its really pretty good for a 48 min. render on my laptop...thanx again gonna keep playing...

Justin Hunt Posted July 5, 2007 Share Posted July 5, 2007 Nice, now up the suns shadow samples (like 100 or so) and up the glossie samples for the floor. Play with the fast interpolate with high detail distance. This gives nice clean glossies that go from sharp to blurry. JHV Link to comment Share on other sites More sharing options...
manta Posted July 7, 2007 Author Share Posted July 7, 2007 Well here it is, I still need to mess it up alittle, make it look more real, but the quality of the render is nice, and it wasn't too hard to get to here, thanx again... Link to comment Share on other sites More sharing options...
Justin Hunt Posted July 7, 2007 Share Posted July 7, 2007 I like. I am intrigued about the two highlights above the couch, looks like light refelction off the floor, what is it> JHV Link to comment Share on other sites More sharing options...
manta Posted July 7, 2007 Author Share Posted July 7, 2007 I put 2 rectangular lights on the opposite wall to represent windows casting ambient light, and giving more contact shadows... Link to comment Share on other sites More sharing options...
Justin Hunt Posted July 8, 2007 Share Posted July 8, 2007 Thought so, although it does conflict with the windows next to the couches. Its a small thing do dont let muy fussing be a downer on a really nice image.. JHV Link to comment Share on other sites More sharing options...
