How to decreese level of distortion?

I have too strong correction by program.
I tried to edit shaders, it is bad way and there is a lot of shaders there. (And I didn't get result yet)
Where is the parameter which I should correct to make distortion lower?



p.s. I also asked question in http://stackoverflow.com/questions/34222876/oculus-sdk-huge-chromatic-abberations-produced-by-program

p.p.s. I found topic https://forums.oculus.com/viewtopic.php?f=20&t=717&p=7001&hilit=chromatic+abberation#p7001 , but it was useless because I have DK2 without ovr_win32_hmddevice.cpp in SDK.

    If you are using the latest SDK, the distortion is done for you by the Oculus software. You should not be manually distorting in a shader or anything like that (which was done way back with DK1). Basically you just render into a left/right eye buffers and the SDK handles the rest.

    There was a previous patch available that allowed you to manually specify the distortion. However I assume the advanced tab in the oculus configurator measures the distortion based on the calibration that occurs.

    Any chance of this type of chromatic abberation correction also appearing on the GearVR? It may use more resources but would be good to have the option to turn it off/on in the program if required

    I have 2 available Oculus Rift.

    One of them has such crazy and big distortion, but the other has not.
    Computer and installable run-time software is the same in both variants.
    Both are DK2.
    Different drivers or spoilage in production?
    How to regulate such parameter?

    You may want to delete your profile, or go into the advanced options and measure IPD again as this effects rendering.

    My IPD setting was not changed when I got new device.
    But the devices visual effects became much better.
    So I suppose it is something connected with driver or hardware(less possible) or something else.

    Now I am also using Unity.
    Where I can get the direct access to the shader? I can't find.
    Is it in the DLL?

    It doesn't use a shader, is uses a mesh, but (in any case) it's not user configurable.

    If you have 2 DK2's, and the distortion is noticeably different, then might I suggest that you have different lenses in each oculus. :roll:

    You probably have a different configuration in your profile. Try delete the profile and creating a new one.

    I am a new user and therefore I cannot create a new thread, so I think this one is the most appropiatte to ask something related to the OP.

    Will the distortion shaders of previous SDK (<= 0.8) work well with the Oculus CV1 optics/lenses? Because of the removal of DX9 support I need to compile my app against an old SDK and therefore I have this huge concern.

    Thanks in advance to anyone who can help me with this.
