I work on a project on a computer for some weeks and everything was fine until I had to copy my project on another computer. In VR mode some strange distortions appears on the helmet. The distortions are not the same between the right eye and left eye and seem to appear where contrast is important. The distortion is noticeable in vertical and horizontal movements.
You’ll find a screenshot attached. The red ans blue products are heavily affected by the problem.
If you are talking about the various color channels seeming to separate near the edges of the screen, this is intended as it is necessary to get the image to display correctly in the headset. Different wavelengths of light bend different amounts when they pass through a lens. In order to counteract this, the video output to the headset must offset certain colors slightly to get them to the correct locations on your retina after passing through the headset’s lenses.
This may not be the effect you are talking about, but that’s all I can see in the image you provided.
Thank you for your answer but i wasn’t talking about the chromatic distortion.
If you have a closer look to the red boxes and compare the right image and the left image you will understand were my problem is.
It don’t look obvious at the first sight on a still picture but i can tell it’s a true mess when it comes into the VR helmet !
I managed to identify the source of the problem : i was using the deprecated function “HMD SP” to increase the sharpness of the picture on the HMD so i switch to the “HMD PD” command but sadly it didn’t fix the issue.
These distortions are less visible on more powerful configs but still present. I’ve upgraded from 4.11 to 4.15 but the results are the same.
Does anyone have any idea on the way to bypass these functions while maintaining a high level of precision on the HMD ?
