mapping problem

[carlangas]

hello,

 

I am doing a streched fabric roof using a polyline imported from acad. the fabric is going to have different attachment points and theyre not going to be in the same plane. i added an extrude mod, then a mesh smooth mod. and a uvw mod. then when I render it looks like when you dont apply a mapping mod. ive tried different things like mapping to faces, planar. etc and get that ugly result. the mat itself is just a vray mat with white for the diffuse color. can anyone help me?? also, is there an easier way of doing this?

 

thanks a lot.
