Renderotica

i'd like to have a G8M and some fish caught in a large net, like those on a fishing boat. 

I'm trying to do something with dforce but i'm not having any luck?

any suggestions ???

Sounds like an ideal job for dForce but it depends on the nature of the net model.

A fully modelled net could be a challenge for dForce unless you have geometries, settings, weight maps and so on just right.

A flat mesh model with a transparency mapped texture on the other hand should be quite simple.

Ensure there is enough geometry in the mesh.
Attach (intersect) a 'helper' (a sphere) on each corner.
Pose the figure above the mesh.
Use an animated simulation - add enough time to pull rather than just yank the net - and move the 'helpers' to pull the net around the character.
Hide the helpers.
Add fish.
Render.
