>even thellier agrees that we got a bug in the driver
Of course I agree but as I am not a Morphos dev you can only wait an eventual driver fix...

As we say here (ironically but it happen in real world too) about query for program fix "Expliquez nous ce qui vous manque dans ce programme et nous on vous dira comment s'en passer" (Please let explain us the missing feature and will teach how to live forewer without it)
[Damn I realize that I am beginning to answer this way too ;-P ]

BTW I am also waiting for glTexCoordPointer(4,GL_FLOAT,...); to be implemented for Wazp3D perspective-texturing

>UVs of all models and the terrain were SHORTs
Of course I agree data packing is a good usage for texture-matrix .... but that was not the initial question

Cheers
