Black line that appears when rendering in high quality

Hi all

I have a problem for which I find no explanation or solution when rendering on Visualize. When I render in high quality, I have black lines that appear horizontally and vertically on the final image.  These black lines only appear when I render in high quality, I have no problem when I do my rendering tests in low quality.

I attached 2 examples to the question to better illustrate the problem. 

What I find even more strange is that these black lines go behind my pieces, so I was first interested in everything in the background, but I couldn't find anything conclusive (I tried to put a larger image in the background, I also tried to change the orientation of the environment, as well as to modify other parameters but I don't know exactly which ones). I found nothing in terms of lights either, even if I haven't yet tried to put an extra light  that only illuminates the background (the problem only appears in high quality, I have to wait 3 hours each time I try if I want to see the result...).

I also attached my render settings to the question, could the problem be from there?

Has anyone ever had the same problem? Anyone have an explanation or idea to test?

Hello

The lines have nothing to do with the rendering settings it seems to me.

The lines correspond to the xy or yz positioning.

Simply remove the display of these position indicators.

Kind regards

Look in  Tools ==> Options ==> 3D Window ==> at the bottom there is ==> display option ==> axes of the environment

Hello

If you talk about the big black arrows in the photos, they are arrows that I added myself to highlight the black lines I'm talking about. If you are indeed talking about the thin black lines over the entire height/width of the image, I don't think it is related to the axes of the environment since several lines are parallel. I think the axes would also appear when rendering in low quality anyway if it was really the axes, which they aren't.

I finally solved my problem by adapting the resolution of my image, I think I had pushed the resolution too high, so I preferred to make a larger image with a slightly lower resolution, and the problem disappeared.

Kind regards.

Hello @Metzog 

Really very happy that you found the right solution.
I didn't understand the arrows (gulps) but with the software nothing surprises me anymore.

Quite between us, many people make an excessive definition for most of the time to send or use an image .png or worse a .jpeg or look on their screen with resolutions lower than 2560 x 1440 or for the richest 3840 x 2160 pixels (16/9): 4K/UHD TV format

Very high definition is only used in specific cases, especially for enlargements higher than A3 or even from A2 for paper.

Good luck

Hello @Zozo_mp, you forget that a rendering higher than the screen resolution allows you to zoom in the image to appreciate the details. An image is not always just a 1:1 wallpaper.

Hello @Sylk 

Well done!

Except that you can't zoom in on the image other than in 2D. And it also depends on the format of the image output, an A3 takes an insane amount of time.

If you turn the part in Visualize it re-calculates everything. Even in the pro version allowing you to make a small film, it recalculates each frame.

See you soon @Sylk  ;)  ;)
