Hi Fitz,
Hi,
seems like it was part of the problem, but not all of it.
Intel HD4400 and my AMD Cards still work fine, but the Quadro 600 is missing
all light it seems, it s much darker then it shoud be, it seems like not all
lights are used.
Furthermore, trying to get the shader work on the GTX 660 TI or 670 or
something from NVIDIA is still not working, or it's messed up. (No Bingo, but
still false light or all white).
In my experience the NVIDIA drivers are far better than the Intel or AMD
OpenGL drivers. But I agree, sometimes they seem to silently get strict,
which can cause some hefty amount of wall banging your head.
Once I cased a bug, having an uninitialized vec3 outside a loop in a
blur shader, causing similiar artifacts.
The only suggestion I can give you here: try different driver versions,
check OpenGL errors, step back to a minimal example and debug what is
causing the error.
Furthermore, the CommandLine is giving constantly:
"warning: detected opengl eror 'invalid enumerant' at after
RenderBin:.draw(...)"
Could you attach gDebugger or a similar tool to check what is causing
the error?
It should maybe maintain, that the working AMDs are running on Windows, while
the Quadro 600 runs on Linux. But the non-working GTX ones are runnning
windows, too.
Does anyone have an idea or an suggestion? Or would at least be so kind to
answer me and tell me, that he has no idea? It is kind of depressing, posting
questions and never get any answers. Seems not very noob friendly here to me...
Your question is extremely and seems to be rather shader/driver related
than being an OSG question. People simply don't have that much time to
dive into a rather open ended topic like this.
Next time it might help to provide a complete compiling example which
shows the problem, so people might test on different platforms (which
you didn't mention as far as I see).
Cheers
Sebastian
Thank you!
Cheers,
Fitz
