thatst no problem, but as far as i know it is only possibel to scale the
backdrop or overlay with only one parameter. so you have can not scretch into x
direction independent from y direction.
paste this code into a empty behavrior and put it onto a empty shockwave3D
member on stage.
you can use as many textures as you want, or simpy change the source of the
texture by another castmember.
take a look into the help files for: overlay, backdrop
property pMember, spritenum, n
on beginsprite me
newtex=pMember.newtexture("tex01", #fromcastmember, member("tex01"))
pMember.camera(1).addBackdrop(newtex, point(0, 0), 0)
on exitframe me
n= n mod(360)
