I am moving towards the idea that we may only be able to catch on the
fly bad usage and disable the arrays that don't have a VBO assigned
when trying to render with VAO, and emit a warning. this will be
better than having an application crash.
I'm going to re-factor the existing places in the OSG

Hi All,
I've started investigating what is happening in the VertexArrayState
that is passing the array data to OpenGL. When things are all set up
correctly w.r.t VBO assignment to the Arrays we get:
VertexArrayState::setArray(VertexArrayDispatch, new_array=0x1092250
vbo=0x7f583c09d210
Hi Dan, et. al,
I haven't yet got to bottom of this issue, but so far it looks like
doing the Array::setBinding(Array::BIND_PER_VERTEX) call later than
the array itself is assigned to the geometry bypasses the mechanism
that osg::Geometry uses to make sure all the arrays that need a VBO
have one
ther (and

Hi Dan et. al,
I have had another look into this issue, looked at Dan's workaround
and used Dan's test example to see investigate what might be going on.
I have checked in a fix:

Hi Daniel,
I don't understand why your modification to addPrimitiveSet() resolves your
issue with the openflight plugin, as it's called before the proper array
bindings have been set (src\osgPlugins\Open

I have built the example, and to help with test
Could this be why I'm not getting my colors?

Hi Dan,
Thanks for the explanation and example to reproduce the bug... Guess
it looks like we'll need to make 3.6.2 rather sooner than I was
hoping, it'll be one a month at this rate...

Hi Robert,
Oops -- I sent this earlier today but apparently to the bounces list; that
explains the confusion on GitHub -- my mistake. This was supposedly sent right
before I posted the PR. Here's the original text:
I think I found a bug in 3.6.1. I am loading a FLT model and it's causing a
