nisus Posted November 18, 2003 Share Posted November 18, 2003 Hi all, I'm running the max6 demo, but can't get a decent daylight animation using MR. I've set up a simple room and an animated daylight system from 0600 till 2200 but can't get it to calculate a animation. Rendered on a per frame basis I got a nice GI-effect, but when calculating a sequence I only got direct illumination. I've turned on the 'compute advanced lighting when required'-checkbox, but that doesn't help either. Anyone got a clue on how to solve this problem? rgds nisus [ November 24, 2003, 03:33 PM: Message edited by: nisus ] Link to comment Share on other sites More sharing options...
DelfoZ Posted November 18, 2003 Share Posted November 18, 2003 no idea, btw, post some images with GI i'll be happy to see some test of u with max 6.. And what u think about max 6... better than max 3.0 ? Saludos.. Link to comment Share on other sites More sharing options...
abicalho Posted November 18, 2003 Share Posted November 18, 2003 Nisus, Compute Adv Lighting has nothing to do with MR. For you to have Skylight and GI in MR you need to use GI and/or Final Gather. Sky works with Final Gather. But IES Sun and Sky are not supported by MR, so you need to use regular Sun and Sky. Alexander Link to comment Share on other sites More sharing options...
nisus Posted November 19, 2003 Author Share Posted November 19, 2003 Hi delfoz, From my point of view max6 is the first upgrade from max3 that's worth upgrading for arch. vis. Many tools that were available in max5 have been refined and so are finally useful. It's really better, although the artist is still the most important factor to make great images. Hi Alexander, I thought so, but gave it a try anyway as I don't know how to solve this problem yet. For you to have Skylight and GI in MR you need to use GI and/or Final Gather. Sky works with Final Gather. But IES Sun and Sky are not supported by MR, so you need to use regular Sun and Sky. I RTFM the whole time, so I knew these things allready... Still wondering why an animated sun won't work... Anyone got a clue??? rgds nisus Link to comment Share on other sites More sharing options...
abicalho Posted November 19, 2003 Share Posted November 19, 2003 Nisus, Works fine here: http://www.origamy.com.br/mr_daylight.zip Let me know what you're doing differently. Alexander Link to comment Share on other sites More sharing options...
Carlos L Posted November 19, 2003 Share Posted November 19, 2003 MAX 6 is a reaaly great upgrade... altough there is a mayor feature missing: the File Link Manager. anyway... I have been a VIZ user for nearly 4 years and this is my first MAX, so i am really happy with all the new tools i've got. Link to comment Share on other sites More sharing options...
nisus Posted November 20, 2003 Author Share Posted November 20, 2003 Hi Alexander, Tnx for the testfile, it works... But mine still doen't. Can you take a look at it pls? testfile Just calculate the sequence... tnx nisus [ November 20, 2003, 06:04 AM: Message edited by: nisus ] Link to comment Share on other sites More sharing options...

stefkeB Posted November 24, 2003 Share Posted November 24, 2003 I'm sorry, but my PC (Dual P3 1000 MHz) is just too slow to dig through these caustics in an animation. I had to turn down so much settings that it isn't even nice anymore to look at... It seemed that the caustics worked in animation, though. Don't know about the GI. But it is clearly different from the renderings where Indirect Illumination is enabled. --- The file from Alexander rendered OK, but I had to adjust the settings as the rendering took a long time (especially on the reflecting sphere). The option "Fast Lookup" in the FG settings helped a bit. And turning off Preview did improve quality (what is to be expected). --- Otherwise both scenes are just too slow on my machine.

nisus Posted November 24, 2003 Author Share Posted November 24, 2003 Hi StefkeB, Tnx for the time anyway. rgds nisus ps: anyone else? Link to comment Share on other sites More sharing options...
CRD Posted November 24, 2003 Share Posted November 24, 2003 Nisus, Well, I've downloaded and played with both files and the major difference is that you have Caustics and GI turned on, but no Final Gather, while Alexander has no Caustics or Gi and only Final Gather turned on. When I animated your file (and I turned off caustics for speed, but kept the gi turned on), the shaft of sunlight moved across the floor, but no gi. http://www.cgarchitect.com/forum/filepush.asp?file=204-animated.jpg When I rendered a still, the gi showed. That is strange. http://www.cgarchitect.com/forum/filepush.asp?file=204-gi-caustic-still.jpg Then, just for fun, I animated the false-color photon map and it looked correct. The progress bar shows me that photons are being calculated, but then they don't show in the render window, but then when it is converted to the color map, it shows up again. Where did it go? No idea. http://www.cgarchitect.com/forum/filepush.asp?file=204-photon-density-ani.jpg Also, just for comparison, I rendered with gi and final gather... http://www.cgarchitect.com/forum/filepush.asp?file=204-gi-c-fg-still.jpg I can't figure out why your GI shows in stills, but not when animated. I'm new to all of this and I'd to find out the answer for later. Sorry. Colin Link to comment Share on other sites More sharing options...
nisus Posted November 24, 2003 Author Share Posted November 24, 2003 Hi CRD, Tnx a lot for taking the time to look at the file and posting your tests. The results I have are just the same (except that I did calculate the caustics). I have no clue how this happens! Btw, I turned of gathering (in contrast to what the manual claims) because the result is actually MUCH better without (for this scene!). Anyone else who will give it a shot? rgds nisus Link to comment Share on other sites More sharing options...
nisus Posted November 30, 2003 Author Share Posted November 30, 2003 Hi all, I still haven't found the problem. Will anyone pls take a look at the file? tnx nisus Link to comment Share on other sites More sharing options...
ZepSOFD Posted December 8, 2003 Share Posted December 8, 2003 Nisus, I don't know if you are still looking for an answer to this, not that I have one, but I was able to render the scene w/GI. I only made a few changes, most dealing with quality to produce the vid. snipit quickly. I saved and zipped the file I used to generate the vid. snipit, try and see if it works for you. http://www.wellespugsleyarchitect.com/tom/test.zip http://www.wellespugsleyarchitect.com/tom/test.avi The .avi is in divx format. tom Link to comment Share on other sites More sharing options...
nisus Posted December 8, 2003 Author Share Posted December 8, 2003 Tnx Zephod (THHGTTG? again!) Yes, I'm still looking for an answer. I had a second and third file that had the same issues. Could this be because I run the demo? It seems to me that the sunlight doesn't change when animated... Rendering frame by frame (by hand) works fine, rendering an automated sequence doesn't... Anyone? (Alexander?) rgds nisus Link to comment Share on other sites More sharing options...
ZepSOFD Posted December 10, 2003 Share Posted December 10, 2003 Nisus, I don't think it is a problem with just the demo version. I continued on trying to render your file with just GI/Caustics and not use Fin. Gath. at all. I remembered reading somewhere to start a sequence render on frame 1 instead of 0 when using MR. So starting with frame 1 of your scene I was able to render GI/Caus. for X number of frames then it would stall, I would have to advance a frame and start again until it would stall again. After a hundred or so frames I scrapted your file and recreated my own. I was able to render a couple hundred frames when my file also stalled on one frame, I advanced one frame and the sequence finished. I went back to pick-up the one stalled frame and was not able to render it, it just continued to stall over and over. I replaced the frame with a re-render of the previous frame, thinking you might see a flicker but it would barely be noticable, and what do you know it was completely annoying and very noticeable. The light intensity of the rendered still was nowhere near that of the same frame rendered as part of a sequence, as you know rendering the still looks good, but as a sequence they seem to render darker and problematic when using the daylight system. If you do find an answer please post back here because I am very interested on how this will be addressed. Thanks, tom Link to comment Share on other sites More sharing options...
nisus Posted December 10, 2003 Author Share Posted December 10, 2003 Hi Tom, Tnx again for effort. I still have not find a solution, but I'm definately gonna try your suggestion: to start a sequence render on frame 1 instead of 0 when using MR. I'll get my hands on all files again since no rendered a proper sequence yet. In the mean time I've rendered your file with succes, but I don't know what you changed... Although getting focussed on the problem (a lot of possible causes are eliminated so far) I still need help from anybody who wants to try out my file... rgds nisus Link to comment Share on other sites More sharing options...
ZepSOFD Posted December 10, 2003 Share Posted December 10, 2003 The only thing I think I changed that might matter is under the light properties/mr tab I check generate gi and generate caustics, other than that I think I only adjusted the number of photons for speed. Would you like me to post my new file to see if it works any different for you? tom Link to comment Share on other sites More sharing options...
nisus Posted December 10, 2003 Author Share Posted December 10, 2003 Hi Zepsofd, Things work out great now. Idd MR does't calculate from frame 0... very strange, especially since I've not read a thing about it yet! Anyway, tnx... the first scene is ok for now, finally got a sequence rendered. I'm trying the other files too... TNX a lot nisus Link to comment Share on other sites More sharing options...
