gfa2 Posted January 16, 2007 Share Posted January 16, 2007 I've got about a day to get this figured out so I though I would try to cut the experimentation time down and axe the question. What is up with these lights???? When I render at a smaller resolution (500px wide), they don't show up, when I go higher-res (3000px wide) I get all these glowing spots everywhere (I didn't circle all of them). There are 42 lights in this scene, I haven't tried raising the subdivisions of the lights. Any suggestions? 3ds max 8, vray 1.47.03. Link to comment Share on other sites More sharing options...
JamesTaylor Posted January 16, 2007 Share Posted January 16, 2007 looks as if you may have a ray trace map / material somewhere in your scene. Go thro your scene materials with a fine tooth comb and remove any ray trace maps or mats, if you need reflection use the the reflection greyscale value in the vray material Link to comment Share on other sites More sharing options...
andreg Posted January 16, 2007 Share Posted January 16, 2007 if that isn't the problem and you are in a rush to finish, you could easily photoshop them out Link to comment Share on other sites More sharing options...
gfa2 Posted January 16, 2007 Author Share Posted January 16, 2007 The raytrace comment is interesting, but it's very unlikley since I built nearly all the materials from scratch and I used all vray mats. The ones I didn't build were on the plants and I know they don't have any raytrace. It kind of does look like that would be the problem though. Wierd...any other ideas? Thanks andreg, I've done just that incase I can't get this fixed by tomorrow...and you can't even tell that they were there. But it's the principle of the thing...I've just got to know why it's doing this. Some new information...if I do a high-res region render of just an area that had the spots, they aren't there. Only when I do the entire image at high-res. I'd be intersted to hear if anyone else has an idea. Link to comment Share on other sites More sharing options...
Fran Posted January 16, 2007 Share Posted January 16, 2007 The easiest way to troubleshoot a raytrace issue is to turn it off from the Rendering menu. But I doubt that is the problem if all of your materials are Vray. What does the Vray log say? Are there any warnings or errors reported? Does it show up if you use Adaptive AA instead of QMC? What are you using for secondary gi? If it's lightcache, I understand it is camera dependent and a crop or region render that is re-calculated might not encompass the object that is causing the problem. Just some thoughts.

gfa2 Posted January 16, 2007 Author Share Posted January 16, 2007 What does the Vray log say? Are there any warnings or errors reported? Man, that is good readin' there. But no, I didn't see anything that jumped out at me. When the rendering was done, I didn't have any errors in the little Vray message window either. For what it's worth. I have a daytime scene exactly like this but with just one direct light and I don't get this problem. Link to comment Share on other sites More sharing options...
Fran Posted January 16, 2007 Share Posted January 16, 2007 I suspect the lampost light. Is there a possibility that a vray light or light object is intersecting other geometry? ETA The irrmap settings are size dependent. So an artifact may not show up at one res and will show up at a larger size. Link to comment Share on other sites More sharing options...
gfa2 Posted January 16, 2007 Author Share Posted January 16, 2007 I suspect the lampost light. Is there a possibility that a vray light or light object is intersecting other geometry? Fran you rule! I haven't even check it yet, but I know that that is what the problem is. I have the vray light hanging outside of the lamp post a little because I liked the shadows better that way. I'll push them back in and let you know what happens. I'll let it render tonight and let you know tomorrow. Link to comment Share on other sites More sharing options...
Fran Posted January 16, 2007 Share Posted January 16, 2007 Well, I'll rule if I'm right. If it does turn out to be that, and you still want the cool shadows, you can try excluding your lamp geometry from generating GI. I doubt if it is contributing any indirect light to the scene. And it may work. Link to comment Share on other sites More sharing options...
gfa2 Posted January 18, 2007 Author Share Posted January 18, 2007 Well my computer was locked up when I came in so I just turned in the version that I fixed in Photoshop. I'm sure Fran's suggestion is what locked up my computer...thanks Fran. Eventually I will go back and try to re-render that image and I'll post the results. I've had to move on to the next rendering so no time for playing around right now. Link to comment Share on other sites More sharing options...

sterealkey Posted January 19, 2007 Share Posted January 19, 2007 Hi Gfa2 Just a thought here. Maybe it'll go away if you select your lamppost light (if this is the little bugger causing the problem), then uncheck the 'affect specular' box in the options of this light. It might be the same problem that Koper was experiencing a day or two ago. Link to comment Share on other sites More sharing options...
gfa2 Posted January 19, 2007 Author Share Posted January 19, 2007 then uncheck the 'affect specular' box in the options of this light. Interesting...I'll have to give that a try too. Link to comment Share on other sites More sharing options...
