Dennis: I use an aluminum that is really a metal shaded light gray with a reflection map. I'm still not completely satisfied with it, but it looks OK. I'm sure that you've noticed that different "shiny silver" metals look different – the main difference being the exact color of gray that makes up their base color. I've really been amazed at how even a slight reflection map does wonders for the metallic quality of a material. What I need is a really good floor tile that shows the irregular bright shiny reflections that you get because real time isn't flat! <g> Chris – Chris Johnston, Written 06-Jan-1995 @ 23:53:14 Using: Windows NavCIS PRO 1.25

Chris; >> What I need is a really good floor tile that shows the irregular >> bright shiny reflections that you get because real time isn't flat! <g> On my floor it is! <G> Ha! I would suppose that a combination of maps could provide you with what you want. I'm would think that an opacity map of the pattern would allow you to "see through" the rough parts on the top surface to the shiney parts underneath. But I am only guessing. Dennis

Dennis: The problem is that when you look at the floor, you see the tannish-yellow tile, the seams between the tiles – at least for the tiles close to the camera – and, as the distance increases you begin to see bright but irregular reflections in the same color as the lights. They seem to be caused by the fact that A) the tiles aren't really flat, and B) the floors are lit by a series of lights so there are a number of light source – floor – camera angles operating at once. On top of that you still have the "metapattern" problem – where you see large repeating patterns that come from repeating the tile over and over again. There isn't enough randomness in normal tiled materials when you do tile floors, grass, etc… Chris – Chris Johnston, Written 09-Jan-1995 @ 22:00:02 Using: Windows NavCIS PRO 1.25

Chris; >> see bright but irregular reflections in the same color as the lights. Is it possible that you could "exclude" the floor from some of the lights? Would this help. Release 3 has this feature. >> "metapattern" problem – I don't have any suggestions for this one. Dennis

Dennis: The problem with my floors is that there aren't **enough** hilights. I don't think that there is any solution to the metapattern problem – even a random tile map will end up being a **repeated** random tile map. You need to generate maps that are randomized over the entire object to get rid of the big patterns. Chris – Chris Johnston, Written 11-Jan-1995 @ 22:38:25 Using: Windows NavCIS PRO 1.25
