Date: Thu, 18 Jun 1998 18:15:50 +0100 From: George Cole Subject: [IML] QUEST: Light types + Transpar texture Could some-one please explain the difference between 'Controlled Y Fall off' and 'Diminishing Intensity' please? I can't seem to find much help from the FAQ or Dare 2 Imagine. Also what does the 'Transpar' texture do? In my tests it seems it is necessary to make the shadow of a transparent object show the effects of a bump texture on the object (i.e. a change in the shadow colour). Why is this necessary?

There is a formula for exacting how much a light of a certain value will diminish over distance, but it escapes me atm. Control Fallof simply bounds the light to the Objects Y axis. Objects outside the Y radius will not be hit my the light. I've no Idea about the transpara texture. I don't recall if I ever used it. . . ---------------------------------- Date: Fri, 19 Jun 1998 09:46:06 -0500 From: Jeff Krase Well, 'Controlled Y Fall-off' allows you to specify (or control) the fall-off for a given light based on the length of that light's Y-axis. 'Diminishing Intensity' controls the fall-off based on a given distance from the light source. I forget the exact distance, though, but I believe the value is adjusted logarithmically. ---------------------------------- Date: Sat, 20 Jun 1998 01:09:44 +0100 From: Matthew O'Neill Organization: Spectrum [IML] QUEST: Light types + Transpar texture -Reply gets dragged on once more...... For every 256 units the light is away from an object, the light is reduced by ¼, very useful ---------------------------------- Date: Sat, 20 Jun 1998 12:09:28 +0100 From: George Cole Thanks to everyone who helped me with my lighting problem. I now understand all the lighting methods well (the two that I have anyway ;)). ----------------------------------
