deforming geometry

[angels_arrows]

hi, I am trying to deform a geo having displacement map attached to it. The problem is that when the geometry is animated or deformed using bend or twist the surface bends along with the displaced map. The displaced map begins stretching with the surface. I have attached reset position but I am not able to figure out how to isolate only the displaced part not to deform. I have attached the file , thanks in advance !

hi , if this question has been answered or similar, can someone point me in the direction ?

I think the problem here is what you are describing is exactly what you'd expect to happen. If the texture is stuck to the geometry via a rest position and then the geometry stretches then naturally so will the texture. The only way around that is to use a world space texture but if the model is animating it will then appear to travel through the texture space and it won't be stuck to the model.

i hope this is a little clear .. the extruded parts change in volume when the object deforms. Is there any way to stop this from happenin

Not sure how you'd get round that, you could re-project the texture coordinates after the deformation but then the displacement won't look like it's attached to the object. I think it's a big catch 22.
