chriss, see the patches in the girpowerfolder: smallpitchonpole.v4p and gridworm.v4p

u can just replace the earthtexture of pitchonpole with a videotexture. use the nodes filestream and videotexture instead of the filetexture node.

hope this helps a bit, dont have time to explain further going to holiday tomorrow :)))

cheers ele

Hi Tonfilm,

its close to the result what i like to do :-), but I dont need the warping animation. What i want to do is a projecton around a corner and so i have to “fight” with two trapez corrections. Do you have some more details about the ArbitraryPoint?? is it possibel to make manual transformations on specific points in the grid??
I think i could work with two trapez corrections but than its just a solution for this situation. I think it woul be better to have a more flexibel solution with the grid :-) than i could use it for different projects (eg projecton on a curved wall).

Greetz and a big thanks
