creating polygon surface from multiple curves?

Does anyone know how you can make a polygonal surface from multiple curves in Maya? I'm trying to create spiderman webbing using multiple curves as in the image below and can't seem to find a loft/extrude function to work to create the webbing correctly.

Any help is appreciated.

I have no idea how you will be able to do this with what you've got atm skdzines... you may have to try a completely different approach altogether. share quote

Then you have to split up each nurbs "circle" into 4 sections each. Use the EP curve tool to create the intersections and press C when clicking your "circles": that way the intersecting curve sticks to the curve. Then select the intersector, and then the curve and go to Edit Curve > Cut curve After you've done that you use Loft to build surfaces between these curve sections (Uniform, Auto reverse, Cubic, One span). But here is the thing: If you output this as surfaces then you are gonna have a BIG problem merging the surfaces together. That's one of the biggest limitations of working with NURBS: You can't just combine surfaces the same way you do with polys. So output the loft as polygons instead, clean the poly meshes and merge the verts together. I would also like to point out that I think that your workflow has been flawed from the very start. If I were to make a spiderman character I wouldn't use NURBS but make a highpoly mesh and sculpt the webs. OR make a lowpoly, flat mesh without webs, and later paint a heightmap for conversion into a normal map. __________________ Nightshade UV Editor (script for Maya) - Extends Maya's default UV Texture Editor with additional tools. share quote

Thanks for the replies guys! I figured it was not going to be as easy as I was hoping. I actually have a flat pretty high poly mesh of it I created using ZBrush. The mesh is pretty messy so I was hoping to clean up the amount of edges.

Anyway, here is the mesh generated from Zbrush. I'm wanting to basically select about every other edge and delete them. I also want to clean up the areas where the webbing intersects each other, it's pretty ugly. I also have the rest of the body webbing that basically looks the same as this to clean up which is going to be rather time consuming otherwise.

I was thinking I might be able to get a cleaner less dense mesh if I used curves to loft a surface. I took that mesh and did a select all border edges and converted them to curves hoping that I could somehow recreate a lower poly version.

 09 September 2012 DeadlyNightshade Plz...   portfolio Martin Dahlin Jr. Technical Artist King Stockholm, Sweden Nah your mesh is cool that way, but yea you need to reduce the polycount. So check the "Reduce polygons" -tool. Be careful with it though - backup your file just in case. You want to have it keep all the edge borders. And start with a small preservation value of like 75% or so. It's better to reduce polys in babysteps - at least until you get a really good hang of the tool. __________________ Nightshade UV Editor (script for Maya) - Extends Maya's default UV Texture Editor with additional tools. share quote
