[osg-users] Using multiples texture for a geometry

[Florian GOLESTIN]

Hi Robert,

I followed your suggestion and indeed the exported scenes seem different but I don't get this difference.

Please see in attachment for the source code and the exported scenes.

This source code create one drawable with two faces and two TextCoords buffers. The result is the same: if I apply the two texture it's dark. If I apply only one texture (either on the left or the right side) the unique texture is displayed correctly.

I've compared the .osgt scenes.
So there is obviously two 

Code:

Data 1 {
			    GL_TEXTURE_2D ON 
			}




and two 

Code:

			Data 1 {
			    osg::Texture2D {
				UniqueID 4 
			    }
			    Value OFF 
			}



Only one has a reference to the image but I think this is explained because the both have the same UniqueID.

And two

Code:

osg::Vec2Array {
			    UniqueID 11 
			    Binding BIND_PER_VERTEX 
			    vector 8 {
				0 0 
				0 0 
				0 0 
				0 0 
				0 0 
				0 1 
				1 1 
				1 0 
			    }
			}



With different Textcoord as expected (this second part correspond to my right part).

I also tried to create two textures but no more chance.

I'm continuing investigating but I'm kind of stuck

Florian
