Default OpenGL renderer is inconsistent with colours and textures

[Phlogiston90]

Hi Coppelia,

I am using V-Rep 3.6.2 rev 0 together with PyRep, but apparently this is not the source of error. With the default OpenGL renderer, when loading the same scene with a texture a second or more times, the textures disappears.
See also https://github.com/stepjam/PyRep/issues/10 .

Additionally I noticed today that even without textures, the colours do change: Whereas at the first start of an episode, the images look more brownish, at the second (and subsequent) starts it is more grey.

This must be a bug in the renderer because neither of this happens if I switch to e.g. OpenGL3.

Best regards,
Mark

Thanks Mark,

yes, there must be something with the textures and the default renderer, when in headless mode.
Will look into this asap.

Ok, you have a workaround by setting variable oglCompatibilityTweak1 to true in file system/usrset.txt
