Cloth folds
« on: April 17, 2008, 07:25:43 am »

Hi all - anyone give me some guidance on making decent cloth folds - I'm particularly trying to make sails like in the photo - especially the tension creases in the corners - whatever I do ends up either lumpy or with sharp creases -

Bump maps should do it easily RG. :)

Do you need to model the cloth folds? Wouldn't it be far easier (and practically unnoticable) to add the folds to a texture afterwards?

I have done something similar, making sails for a windmill.

The trick is to create the mesh with lines following the creases.  Careful selection of nodes, pulling some up and others down, creases the mesh.  Finally, convert to subdivided.  In my example above I did not perform edge reinforcement, where an extra edge is created just within the edge of the sail, to reduce the effect of subdivision rounding the corners off.

However, In your case, I would strongly recommend creating the sails as smooth regular meshes and applying photographic textures, which include the corner creases.  Applying a bump map of the creases should also work well.  The creases are such a shallow undulation in the fabric that this should work quite nicely.

I would suggest that it is more important, in sails such as these, to get the sewing seams right, making the sails pillowy in a grid shape.  This would be a more pronounced deviation from a flat regular plane than the corner wrinkles, and should be relatively easy to shape in a grid meshed sail, though it may work ok as a bump map as well.

Thanks guys - I'll try all of these suggestions - the challenge is to get a decent resolution pic of big sails - they all seem to be taken at an angle with bad lighting and we don't get a lot of close-up views of schooners around here for me to take my own  ;D
