I did so at first. I called pushmatrix before loadmatrix in pre-node trav
callback. Then restored it by popmatrix in the post-trav callback. It
didn't help. Also the gl man page says:

"pushmatrix operates on the single transformation stack when mmode is
     MSINGLE, and on the ModelView matrix stack when mmode is MVIEWING. It
     should not be called when mmode is MPROJECTION or MTEXTURE."

Hence I changed it to loading id matrix to restore. But none of these
things work. Has anyone worked on texture matrix in Performer (2.0)?

Any help would be greatly appreciated.

thanks
