| Mar 21, 2016 at 20:40 | comment | added | DrStrik9 | I guess I spoke too soon on the solution. MOST of the offending frames have been re-rendered OK with motion blur off, but there are still a few hold-outs which render DARK. I don't get it. This is a bizarre mystery, which makes no sense to me ... still searching for the solution. :-( | |
| Mar 21, 2016 at 19:39 | comment | added | DrStrik9 | Mr Zak solved this, but I got side-tracked and didn't try his suggestion a week ago to turn MOTION BLUR off. I don't know why, but turning motion blur off has solved this problem which has been plaguing me for several weeks. Thank you, Mr Zak! I'm sorry I didn't try your suggestion before. Now my question is: WHY? And of course, I need to be able to corner this bug in a super-simple scene and report it well ... | |
| Mar 21, 2016 at 17:03 | comment | added | DrStrik9 | There are no UV's. All surfaces are simple mix nodes with diffuse and gloss. Alternatively, could this be a bug with CPU render? It's on a 2013 MacPro with AMD video cards (no GPU). I've seen other threads about the differences between CPU and GPU renders. | |
| Mar 21, 2016 at 15:14 | comment | added | Delagone | The only thing I can then come up with is that the uv's are possibly generated? Try ncluding a texture coordinate node in the material and set it to uv.(if it's unwrapped) | |
| Mar 21, 2016 at 11:18 | comment | added | DrStrik9 | Scale: The dimensions of each plank is exactly X = 6.5, Y = 0.5, Z = 1.0. | |
| Mar 21, 2016 at 9:26 | comment | added | Delagone | On what scale did you modeled the scene? | |
| Mar 21, 2016 at 3:37 | comment | added | DrStrik9 | BTW, this is CPU rendering (not GPU). I'm continuing to render this 880-frame animation, and it continues to flicker ... | |
| Mar 21, 2016 at 1:44 | comment | added | DrStrik9 | Here is a side-by-side frame comparison between good and bad: s-media-cache-ak0.pinimg.com/originals/76/43/f6/… | |
| Mar 21, 2016 at 1:28 | comment | added | DrStrik9 | Please see the new scene youtu.be/dviikkFAsRQ at around 7:20. The render was aborted after several bad frames. The darker frames include ALL objects, not just the ground plane. But the ground plane has that telltale 45-degree angle darker triangle, as before. I'd love to share the scene but it is too large to upload. I am stumped, and VERY frustrated. | |
| Mar 21, 2016 at 0:36 | comment | added | DrStrik9 | It's not z-fighting, as stated before. No hidden objects. Nothing in any layer except layer 1. Nothing duplicated in the same space. -- I hate to report this, but on yet another scene (for the third time, with all fresh objects) this is happening again, but the darker frames also include ALL objects, not just the ground plane. The only thing that is not darker on the offending frames is the HDR background. The single lamp (sun) in the scene is NOT keyframed, and does not move or change during the scene. I'll post this render on YouTube with a link when it's finished. Blender 2.77. | |
