Looking very good Rhetoric. I love projects that have multiple objects in it. Good job on the uv layout. Sadly, after 3 years of working with Maya I still don't really know how to layout uv's so hats off to you. I definitely look forward to seeing how it all turns out.

i'm just making things up so i cant point you to a website or anything

but i'd layout one of the rings, then (i've never done this but i've seen someone suggest to someone else to do it) transfer the UVs to 7 other rings and move them around so that all 8 rings have UVs in different coordinates.
then id transfer the UVs from those 8 rings to the rest of the rings. 8 should be enough to take out any sort of pattern that may emerge if you were to give them all the same texture map. and there's enough to randomise it so that if you pick a ring and count 8 up the chain it isn't guaranteed to be the same ring
this way you only have to lay out one ring and the rest is essentially copy-paste

Earlier in your W.I.P. you asked about ways to create the spiral slide. Even though you did an excellent job, here's another method you could try for future projects. All I did was create a cylinder, use a twist deformer then extrude a column of faces outward (twice to create row of faces I could make the side wall from). Then I extruded the outer faces upward to create the side wall. A few more extrudes and some minor tweaking later, you end up with a decent start.

@Perfect Nice to see you here again! You come in waves it seems, or you're posting on the forums and I'm not seeing it. You should really look into learning to UV as much of a pain in the ass it is, it's great to know so that you can really work on dirtying things up a bit. I wish I had thought of that idea for the slide, looks pretty simple in comparison. I'm actually now considering redoing that slide that way. Has a much cleaner finish to it than mine does, which when you look up close is kind of sloppy looking. Thanks for the idea/tip I'll give it a shot and see if it works better than what I have, and if so, I'll replace it.

@Chirone hmmm sounds interesting, not sure I quite get it still. Have to look into it. Or maybe someone else that is browsing through here could throw out a couple ideas? Thanks for the help I'll see if I can find anymore information on that.
