The original render_gl3.c code does the following: ``` mjr_setf4(plane, 0.5*scl[0], 0, 0, -0.5); glTexGenfv(GL_S, GL_OBJECT_PLANE, plane); mjr_setf4(plane, 0, -0.5*scl[1], 0, -0.5); glTexGenfv(GL_T, GL_OBJECT_PLANE, plane); ``` The 4th component of the GL_OBJECT_PLANE function effectively describes a UV-offset for the generates uvs. In our filament implementation, we had overlooked this 4th component.
