Trying to create new texture map for existing model...
OK, so this is what I'm trying to do:
I want to re-do the textures for a specific building on a Dystopian City Block. My understanding is that all the texturing on these models is tiled similar to procedural textures. This is limiting for what I'm trying to accomplish as I'd like to make a surface for the windows that has random lights lit-up (created in Photoshop). Since I only need the one building on the block for what I'm doing, I edited the out all the other structures in the .obj using Sketchup. This simplified the problem of multiple buildings sharing textures.
Now, I'm at the point where my lack of modeling skills are preventing me from moving forward. I assume at this point I need to create new UV maps so that specific polygons are assigned to specific texture groups but I can't figure out how to make this happen. I have Hexagon & Sketchup (mostly for converting formats and, hopefully, for texturing eventually) but don't use either much as my primary focus isn't on modeling. Sketchup's texturing tools feel very limited and in-flexible while Hexagon's interface seems like it has a fairly steep learning curve. I'm sure eventually I could learn Hexagon from scratch and figure out how to do it but I'm really not interested in putting my current project on hold for several weeks while learning all the ins and outs of a modeling program when I won't be using it for that so much.
My question, then, is this: is there an easy way to create a new texture map (template, I guess) that I can work with in Photoshop using Hexagon or Sketchup or possibly some other cheap/free program? BTW, the goal is to use the newly textured model in D|S if that makes a difference - I wouldn't assume it does, but then what do I know...
Thanks in advance for any help!
