Hi Robert,
I think I'll be able to reproduce the artifact I told you days ago (the models
that flickers) in a much smaller source code, but this time it has nothing to
do (I guess) with RenderBin nor a .osg model since I did the same with a
simple box (ShapeDrawable).
I just need a little more
Hi Robert,
Thanks for the openGL explanation.
Well, I already checked for the normals (I didn't know for the
Material/ColorArray, but I knew for this!)... And they're ok (Lighting is on).

Hi Robert and Jean-Sébastien,
Thanks for your ideas. My model is an .osg so I know there is a normal array
and no texturing, and I manually replaced OPAQUE/DEFAULT.
You both said that I need a colour array with at least one overall colour.
Well, can you tell me why I need a colour array? I
Hi Sukender,
However, the first problem still exists and *exists on others configs* (!): changing from OPAQUE_BIN to DEFAULT_BIN removes a strange behaviour.
You mentioned earlier in the thread that your objects did not have a
color array. This is exactly what would happen when that's the

Hi Sukender,
My guess is that the problem is not related to the bin management,
rather missing vertex colour or vertex normals on some of the
geometry. If it's not this then perhaps you have transparency issues.

Hi,
Robert,
Thank you for your answer. I've checked what you pointed. But my exported model:
- Has no coulour array (just a material)
- Has 196 vertex and 196 normals (so probably no missing normals)
- And has no transparency
I really don't understand. Any idea?
Note that I load the model using the
Hi Sukender,
Strange artefacts indeed, but I still don't think they are render bin related.
There looks to be an issue with state leakage, such as with my
suggestion of missing vertex attributes, or perhaps now more likely
given the screenshot a driver bug.

Hi again Robert,
I don't have any custom OpenGL code.
Configuration : Core 2 Duo, integrated chipset (Intel 82945G), Windows XP 32
bits SP3.
Driver is the factory default one, and I never saw such effets in any other
app.
The first bug (strange lightning) has been seen on another configuration,
Hi Sukender,
Intel drivers are known for being rather poor, so it may well just be
driver bug, I would certainly check for updated drivers. Also get
yourself a cheap Nvidia card an pop it in the machine, you may well
get quite a different experience and will give you a sanity test.
Robert.
