| Jul 20, 2023 at 11:10 | comment | converted from answer | Никита Харлов | did you find solution? I have the same problem on Blender 3.6 .... Wtf is this? | |
| Mar 22, 2016 at 15:57 | comment | added | DrStrik9 | @ Mr Zak: Sometimes turning MB on or off and re-rendering a bad frame can correct the darkened objects, but most of the time, this is of no help. It is a great disappointment, and a hugely time-wasting frustrating mystery. | |
| Mar 21, 2016 at 23:08 | comment | added | Mr Zak | So it appears that disabling Motion Blur doesn't really solve the problem ? (btw thank you for your letter, I'm glad to be of help). Unfortunately I can't proceed to testing as I couldn't reproduce the problem (frames mentioned rendered fine for me, but of course I didn't render whole animation). I'm really curious to learn what's wrong with this scene and whether this is a bug. Try importing exact these objects with exact this lighting into another scene and rendering it there. The only thing - what version of Blender do you use ? I don't think I know what's going on there as for now. | |

| Mar 14, 2016 at 17:15 | comment | added | DrStrik9 | @ Mr Zak - In that earlier scene which I uploaded, the same errors happen at difference times. Please try seeing if you get a difference in ground-plane value between rendered frames 0276 and 0277. I will also try your suggestions on the newer/larger scene. On technical diffs, I get the same errors with F12 as with ctrl-f12. | |
| Mar 14, 2016 at 16:42 | comment | added | Mr Zak | Rendered 262 frame of your animation, I don't see anything bad (HDR is another one because yours wasn't packed in file). Still if it persists and is present only on final render then the culprit might be in differences between them. See technical differences for details. Try disabling Motion Blur, changing camera's settings to default ones, using Clipping values as low as possible, change HDR to another one (though I don't think it can be reason), in world material set HDR to Non-Color data. | |
| Mar 13, 2016 at 22:47 | comment | added | DrStrik9 | @Mr Zak - I tried your suggestions: no change. I'm noticing that the lower-res (25 samples) preview renders do NOT have this problem, only the large full-res (150 samples) renders do. | |

| Mar 13, 2016 at 15:45 | comment | added | DrStrik9 | @ diramazoni -- It's 201.1 MB (baked rigid-body) ... I uploaded a simpler scene that had the same problem before, same ground plane asset, no changes ... (see above) ... but I'll try ... NOPE, upload size limit is 30 MB. | |

| Mar 13, 2016 at 14:10 | comment | added | DrStrik9 | Here is a visual comparison between GOOD frames and BAD frames: s-media-cache-ak0.pinimg.com/originals/62/fd/60/… These are rendered as 16-bit TIFF, if that makes a difference ... | |
| Mar 13, 2016 at 13:41 | comment | added | DrStrik9 | This morning I am seeing this same bad rendering behavior on a different scene. At Fm 262 onward, the ground plane is rendering darker, with a dividing line between darker values at a 45-degree angle, with half of the plane color rendering even darker. This is RUINING the render. I tried rendering the offending frames again, but always get the same horrible result on those particular frames. :-( Why, why, WHY? | |
| Mar 6, 2016 at 17:37 | comment | added | DrStrik9 | There are no coplanar polys anywhere in the scene. Blend uploaded.<img src="http://blend-exchange.giantcowfilms.com/embedImage.png?bid=1086" /> | |
| Mar 6, 2016 at 15:56 | comment | added | PGmath | Could be z-fighting, make sure you don't have any coplanar overlapping geometry on the ground. Could you upload the .blend? | |
