Hi Guys
I've been trying to run the osganimationhardware example for osg 3.0.1 on
windows7 32bit with Geforce GTX 560 and latest drivers 280.26 . In the past
I have had this running (not on this machine or osg version), I simply
downloaded the osgData collection with the nathan.osg and skinning.vert
shader file.
However now when I'm running it, anything that is skinned does not render. I
have altered the shader to just use the gl_Vertex position rather then the
weighted position and then the object renders (so verts are fine). I have
also used the boneWeight0 uniforms to colour the mesh and they seem to have
decent values.
The only thing that doesn't seem to have good values is
uniform mat4 matrixPalette[MAX_MATRIX];
When I checked the converted shader the value of MAX_MATRIX seems to be set
correctly, but if I used the first line of the first matrix as the colour
value, like
gl_FrontColor = matrixPalette[0][0];
It is always black,
Looking at the uniform attached to the geoms stateset I can see roughly the
following in the debugger
_uniformList = [2](("matrixPalette", ({_ptr=0x0d0bfb58 },
0)),("nbBonesPerVertex", ({_ptr=0x0d0bf3b8 }, 0)))
_ptr = 0x0d0bfb58 {_parents=[1](0x0d0bfed8 {_parents=[1](0x00df9bf8
{_name="" _dataVariance=DYNAMIC _userDataContainer=0x00000000 })
_modeList=[0]() _attributeList=[1](((PROGRAM, 0), ({_ptr=0x0d0bc9c0 }, 0)))
...}) _type=FLOAT_MAT4 _numElements=3 ...}
osg::MixinVector<float> =
{_impl=[48](1.0000000,0.00000000,0.00000000,0.00000000,0.00000000,1.0000000,0.00000000,0.00000000,0.00000000,0.00000000,1.0000000,0.00000000,0.00000000,0.00000000,0.00000000,1.0000000,0.99998939,0.0046100151,0.00000000,0.00000000,-0.0046100151,0.99998939,0....
So if the colour is the first vec4 of the matrixPalette uniform it should
be 1.0000000,0.00000000,0.00000000,0.00000000, but it's just black.
Can anyone confirm the osganimationhardware example is currently working
with these assets

Any help would be awesome

I mention it as originally I dived straight into trying it without any fixed
functionality essentially emulating gles2, but had this same issue. I've
then gone for the more standard build above, but the result is the same
(although now I see objects that aren't skinned) If I can get this working
again on desktop then I don't think getting it working on gles2 will be too
much hassle (unless I hit some shader variable length limit).
Also standard osgAnimationViewer works fine
