UV Mapping and Texture Mapping
Today in class we learnt how to put texture on a model in Cinema 4D and Photoshop and how to create UV map of model. We took an example of a sphere and gave to 12 segments then make it editable polygon. Then change Cinema 4D layout to UV. Cinema 4D would of created a default cut out but we want to create our known. Then selected the edges tool and selected the edges in a way shown on the screen shots below. Then we need to save the selected edges going to the top bar, clicking select Geometry then set selection and that will saved the selected edges as a triangle icon next to your object in the bottom left hand box.
Then we want to put the UV map we created into the top right hand box (all my screen shot are of the final UV map none of the default UV map) To do this you need to selected all UV Map in the top right hand box (alt + left mouse click and make sure live selection clicked on) now look in the the bottom right hand box and change it to Projection, click on flat and that will give you the flat side of the sphere shape. Next go to Relax UV than next to projections. Here you need to drag your triangle (selected edges) into the cut selected edges box, un-tick Pin Border Points and tick cut selected edges and use tag and Apply and you have UV map like on the screen shot below and above.
Don't forget to resize your UV Map to fit in the box.
Now we need to create a new texture layer, make this white. You will find this in the top right hand box under file, new texture layer. Next make a new layer in the bottom right hand box (click on the layers selection) then create UV mesh layer and put the back lines in, save as TIFF so it keep all the layers. Open up Photoshop, colour up the line art, save, drag and drop in cinema 4D and Ta Da.... All Done ^_^
Creating a more advanced UV Map for a Character Model. Made in the same way as above but with more pieces.
