jinsley Posted September 23, 2009 Share Posted September 23, 2009 Hi, Playing around, getting some materials and set-up ready for next week... FG map works fine, but when the image renders I get these black vertical streaks of missing info... any ideas? Also, only when I render larger size (2000 PX + wide...), this suggests RAM doesn't it? BUT the render dialog only shows 3.4 gigs being used... This is new this morning, rendered fine yesterday. Thx for any help. Eventually this has to go up to 8000 PX, and I need to figure this out.

SandmanNinja Posted September 23, 2009 Share Posted September 23, 2009 Not sure but sounds like RAM. A test would be another scene perhaps? As a work-around, you could bust the render up using the Render-A-Large-Scene script. Link to comment Share on other sites More sharing options...

As a work-around, you could bust the render up using the Render-A-Large-Scene script. I suspect RAM issues too... but it would be weird because I just rendered out some large renders (9000 x 5000) with heavier geometry (4 mill polys) last night... maybe the extra weight of the photon calculations from the lights are causing it. Joel, thx for the quick response, I am rendering another dusk scene now with less lights to test and then a day lit scene again. Are you referring to Zap's script for large renders? I love it, but it has been a while and can't remember where the bloody thing saves the images! I wish you could specify a path... Link to comment Share on other sites More sharing options...
SandmanNinja Posted September 23, 2009 Share Posted September 23, 2009 yeah, that's the one... I *think* it sticks it in the My Documents\3ds max\render output folder but can't remember 100%. Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted September 23, 2009 Share Posted September 23, 2009 I don't think think this is RAM. I think something is corrupt in your scene, most likely a piece of geometry. Now to narrow down what is corrupt. - I would do a material over ride and see if it happens then. - If it is still there, I would turn off displacement if it is on, and see if it happens then. - If it is still there, I would delete any extended, over sized ground planes, and see if it happens then. - If it is still there, I would create a new camera, and see if it happens then. - If it is still there, I would turn off proxies and see if it happens then. - If it is still there, I would turn off half the layers, and see if it happens then. - If it is still there, then I would work my way through the layers, rendering one at a time until I identified the problem.

Justin Hunt Posted September 24, 2009 Share Posted September 24, 2009 do a search on http://www.mymentalray.com from memory this issue has been discussed there, but I didn't follow the thread so cant remember the solution jhv Link to comment Share on other sites More sharing options...

Macer Posted September 24, 2009 Share Posted September 24, 2009 I've had a similar issue before. After quite a few trials I guessed that it was caused by proxies with an opaque material (shrubs). The funny part is that when it is rendering only a single square (the size of one bucket) shows black, but when it finishes a black line runs from the dodgey bucket to the top of the image. The more dodgey buckets the more vertical black lines! Didn't have time to get to the bottom of it, just did a save image as the last bucket was rendering (before the vertical black lines appeared) and ps the missing areas. I thought that it was just my setup, but if it is affecting other people maybe it is a known issue? Let us know if you get to the bottom of it....

Macer Posted September 24, 2009 Share Posted September 24, 2009 Further info here: http://area.autodesk.com/forum/autodesk-3ds-max/autodesk-3ds-max--3ds-max-design-2009/heavy-bug-in-mental-ray-36/page-7/ Seems it was an MR bug, fixed in 2010, with an output shader now available to sort 2009.

Played with the scene as suggested and pretty much narrowed it down to the grass. Changed the material and it got better, seems to be tied to the reflection (turned to 0) / glossy values (set to 1)... not completely fixed but better. Thing that gets me is that when I render the scene without re-using the fg map to render larger, it is fine (attached, 4000 px render). As soon as I re-use the fg map no matter what resolutoin, I get the streaks... Link to comment Share on other sites More sharing options...
jinsley Posted September 24, 2009 Author Share Posted September 24, 2009 Blog entry explaining the problem I think... http://blog.duber.cz/tag/errors sounds like another one of those occurances that confuses all until Zap sheds light on the situation. I have attached the lens shader that will apparently fix this... testing it out now. The Area says this bug has been fixed in Max 2010. Link to comment Share on other sites More sharing options...
