Texturing of cutting objects:
This section covers texturing of objects which r bieng cut..which include texturing of the outer surface as well as the inside visible surface..(say when a wood is cut you will be able to see even the inside concentric woody surface) for this
you may need to start form the beginning... let's say the previous chapters are for practice.. so let's texture a cutting wood:
1) When you've created the cylinder "wood" before doing anything apply a wood bitmap texture to it. See the image.
Follow the same steps to cut the 'wood'. Now when you have animated the boolean, then you will notice that the inner part of the wood has wood texture with face map (that is one whole map per face, which looks highly tiled) see the image.
2) To fix that apply edit mesh on top and go to poly-mode, here you'll see the intersecting polys are already selected..
Now go to frame 30 (where the cutting elements are separated) and apply to that sub-object, a bitmap with some texture like the inside part in wood....(search for such an image or create your own)
3) Then apply a UVW map modifier on top with the' poly sub-object mode' active (or it will alter the previous wood mapping co-ordinates) let the mapping type be "planar"... NOW your mapping tension is solved.. see the image
Now apply an edit mesh modifier again to select the separate cut element, for further animation using the X-form modifier. see the image
This way you can get a completely textured cutting animation..
Though this was a basic idea for creating such cutting animations using BOOLEANS, though you can experiment on your own with combination of boolean and some modifiers to create for awesome dynamic effects.. though BOOLEAN has some problems, like is alters the mesh topology, still it can produce some decent effects and you can play a bit with it to get the effect you want.
