Aaron2004 Posted January 26, 2007 Share Posted January 26, 2007 This is my first attempt at a VRAY WIP. The piece isn't fully finished yet when it comes to furniture, car windows etc. However, I wanted to start getting some feedback while I'm still working on it. The biggest problem I am having right now is light burn. I am using Linear Color Mapping, which lends itself to burning...I know...but it seems like the other ones that I tried make the spots that I feel are perfect in this image drab. I have one direct light for a sun and an area light in each window facing in. Is there any way that I can tell a certain material/object not to burn? Other than that, let me know how it is. Thanks!

mfured20 Posted January 26, 2007 Share Posted January 26, 2007 hey hey be sure to add your landscaping outside.. for instance, i dont see any walkways to get in to the house. i would also change the angle of your sun light so that it lays more at an angle; as it is its kinda hard to see exactly what is happening at the shadows at the top of the image. also, by adding one light at each window, the interior shadows are a bit confusing... the lighting is inconsistant. but at the same time, i dont know how i would do it, besides maybe just totally eliminating the roof and letting the outside light in. good luck dude, id like to see how it comes out!

Aaron2004 Posted January 26, 2007 Author Share Posted January 26, 2007 Thanks for the reply.... Yeah...the one thing that I don't like about this whole plan is the inconsistent lighting...but I don't really know any way around it. There obviously must be, because I've seen a couple examples that do a good job with this. This is the image I'm trying to replicate. Link to comment Share on other sites More sharing options...
ApeiNe Posted January 27, 2007 Share Posted January 27, 2007 try to put down a little your lights multiplier, and using Exponential color mapping can also help you. Just uncheck you ceiling as "Visible to camera" That's it btw, you said "area light", are you using standard MAX area lights instead of "Vray lights" ??

saurus Posted January 28, 2007 Share Posted January 28, 2007 When trying to setup lighting in your interior scene try to adjust (rising and lowering from )the GI multiplayer for all your scene objects like (walls, selling, floor and furniture) so you get better control over the over exposed object and give a good lighting solution to do that : right click the object and vray proprties GI multiplayer use irradiants for 1st bounce and light map for secondary bounce for indirect lights keep posting , ill be watching you;) Link to comment Share on other sites More sharing options...
Aaron2004 Posted January 30, 2007 Author Share Posted January 30, 2007 Thanks for the advice guys...I'm kind of on hold for this...something else came up...ARG. I'll post my work as soon as I get some. Link to comment Share on other sites More sharing options...
Aaron2004 Posted January 31, 2007 Author Share Posted January 31, 2007 I have a lighting update. I am fooling around with the Gamma...and that seems to really balance out the scene a lot. Unfortunately, it seems to desaturate everything. I can fix this by taking it into photoshop and simply upping the saturation. (2nd image) I am still using linear color mapping with a light in each window. I started reading up on Gamma correction (the whole 2.2 stuff) and LWF, which leads to 2 questions that I have. 1. I use an LCD. Is Gamma correction necessary? I've heard different arguments and it's just confusing me not helping me. 2. If I render out a Gamma corrected image, save it as a JPG and open it in Photoshop, it looks terrible. If I save it as an .exr, it looks as it was rendered. Does this make sense? 3. Is there a better way to fix colors in photoshop besides raising the saturation? I used to use brightness/contrast then discovered levels...is there a more precise command similaer to levels but for saturation? Thanks!

Aaron2004 Posted February 1, 2007 Author Share Posted February 1, 2007 Little help here? I just want to know if fooling with Gammas is the way to go or if I'm going in the wrong direction. Thanks! Aaron Link to comment Share on other sites More sharing options...
FlytE Posted February 1, 2007 Share Posted February 1, 2007 I often use Image/Adjustments/Curves... in photoshop. Create a slight 'S' shape on the curve and it really helps give depth to the image. Link to comment Share on other sites More sharing options...
ApeiNe Posted February 1, 2007 Share Posted February 1, 2007 You can modify color mapping as I told you up, or use Curves to control intensity of light/shadows. In photoshop, but also directly in 3dsmax if you activated the Vray Frame buffer Link to comment Share on other sites More sharing options...
3D_IC Posted February 2, 2007 Share Posted February 2, 2007 The rooms are looking spot on to me, but the car is very bright and distracting. It makes the whole scene feel over saturated. Make it a silver or dark coloured car and i think you'll notice a big difference. Link to comment Share on other sites More sharing options...
Aaron2004 Posted February 2, 2007 Author Share Posted February 2, 2007 I have an updated version. I tested out some other Color Mappings again. No dice. I like Linear with a Gamma tweak. I took this into photoshop and upped the saturation by 50%. It renders out very unsaturated because of the Gamma. I need to tweak the tiles. But that is all for next week. Have a good weekend, all! And thanks for the help. Aaron Link to comment Share on other sites More sharing options...
mfured20 Posted February 3, 2007 Share Posted February 3, 2007 yo, for the gamma... i always get the color i want in photoshop, then import it into imageready. theres an adjustment there for gamma. you can fool with it there, try a setting of about .45 [if you have imageready, that is]. then reimport back into PS and save it. see how that works, i do it for just about everything i do.

Aaron2004 Posted February 5, 2007 Author Share Posted February 5, 2007 I tried this...but it makes little sense. If I import an exr into photoshop, change the gamma, convert it to 8-bit, change the saturation and export it to imageready...what else can it do? I've already changed the gamma in Photosohop. Please expand? Thanks! Aaron Link to comment Share on other sites More sharing options...
mfured20 Posted February 5, 2007 Share Posted February 5, 2007 wow, i think i totally misunderstood what was going on, and placed advice where it had no buisness being placed. i thought [for some reason], you were adjusting your textures to work in Linear Work Flow and that you were adjusting the gamma before rendering. i laid out my method of working to do this... which brings to my attention that i am using an older version of photoshop that doesn't let me adjust gamma, and i have to bring it into imageready. furthermore, i havent gotten into floating point images much. so, lets just say that i am behind, and gave mistaken advice. Sorry! good luck with your stuff anyway, sorry i couldnt help.... Link to comment Share on other sites More sharing options...
mfured20 Posted February 5, 2007 Share Posted February 5, 2007 hey one more thing... the best way i found to help me understand working in LWF, in terms of saving out as floating point images, gamma correction in vray, and all of that was from Chris Nichol's Interiors DVD from the Gnomon Workshop [free plug, cpnichols!]. There are a lot of other tuts out there for it, but seeing how it works live on a video feed helped me a lot. im not a master of using it by any means, im still learning, but i got a good feel for it straight away from the dvd. link: http://www.thegnomonworkshop.com/dvds/cni02.html Link to comment Share on other sites More sharing options...
