__I've never really used 3D feature, now I have to mockup a bag of frozen veg...

I've never really used 3D feature, now I have to mockup a bag of frozen vegetables (50 in fact). I've made a grid that I was trying to use to 'warp' it (to no avail) - the artwork is on the right. I'm not sure if Photoshop or Ai is the right thing to use... I don't have a 3rd party 3D program unfortunately.

Thanks in advance!
