#Reflection mapping
3 messages in this thread
I've been having some problems with non-flat auto reflection mapping
lately. I've got a scene I've been working on since r2 – there's a
cup (sides are straight up and down) that's got an auto reflect map
set at about 50%. It used to reflect and it seems like it just kinda
quit. No matter what I do I cannot get it to reflect anything. I've
tried creating a new cup object in r3, adjusting the lights,
adjusting the camera, adjusting the material and it refuses to
reflect anything. I've made a .cub and it is blank also. I've also
got three droplets of water that are also supposed to reflect but they
refuse too. The counter top is a flat mirror and it reflects
perfectly. Any ideas? I know it can be difficult with no file to
examine but this is just so weird I thought someone may have an
idea…

Hmmm…sounds like a sticky one, David. I think the first thing I would try is
putting a simple sphere in your scene — right next to your cup — and trying
to get that to show an Automatic Environment map reflection. If it works for
the sphere but not the cup, then you know the problem is with the object (or
the way the maps are being applied to the object). Oh yeah, make sure there is
plenty of stuff in the scene to reflect! BTW, while rendering, do you see the
maps being made?

Check out the rack of pool balls on the pool table found in the
sports directory of R3's CD ROM. Most of the balls have automatic
reflection mapping and when you render the camera that's zoomed in on
the balls, the result is quite pretty. Check out the materials in
M-EDIT for ideas….
