ok so we need a billboard. I will do it good :P

ok so our final shot includes a billboard so i offered to model one with my basic modelling skills the use N Cloth to create the smash. So on a beautiful saturday i started modelling the billboard that went better than i expected and after an hour or just over. i had a billboard

Ok so now i need to get the NCloth sorted so i got the polygon cube that makes the banner and made it an NCloth object.

Then i selected the vertices down each end of the banner and added a Transform Constraint this then essentially pins each end of banner.

Then i made a polygon plane and used the split polygon tool to split the plane into 2 and then i used the detach component button and then i selected all the faces on on part of the plane and pressed detach to separate these.

I then selected vertices on the inside of each half and merged vertices. I then selected both halves and used triangulate. selected them again and pressed smooth.

Then i selected both again and created an NCloth then went to vertex mode and selected the corner vertices of each half and added a transform constraint to pin them in place.

I then went to edge mode selected the edge of both halves and then pressed To vertices this selected all outside vertices. Then i deselected all the vertices that i did not want to weld together.Then pressed weld adjacent border.

I then selected the weld constraint and lowered the GLUE STRENGTH and then added a sphere to test it out and made that a passive collider.

I then key framed the sphere to collide with the billboard.

It has a way to go to look perfect but its getting there.

ok after adding a few more constraints this is a lot better
