Dr.Willard,
Is this for TR3, TR4, or both?
(I hope) he was refering to TR3,
: : Fade 1 - It is the transparency of the light. If it goes a colored light, it is leaving of transparent (0) to the complete pigment (255).
: That does not make much sense to me; do you mean the strength of the color? --- yes, what I've seen...
what I tried w/ the TR3 lights was to "pick some favorite shades"
of RGB combinations in PhotoShop..
I actually used the numerical values right into
Roy's TRitem "lighting sub-section"...
it worked slick..
for instance: it was possible to distinguish
the differences in "apparent light/shading/transparency
values" just by comparing 2 different hues of the same
"olive drab" colored lights in the same test room.
(& there were the PShp "RGB # values right on my notepad
in front of me.)
in other words, by adding "color contrasts" to a color
(this reduces the "gamma" maybe?) it was possible to get
very suble "green tint/glow" in a noticible part of
Lara's test room...seemed "transparent" even..(?)
: The equation would be something like:
: f = (Fade 1)/(its maximum value)
: (actual color) = (1 - f)*(white) + f*(room color)
: : Fade 2 - The intensity of the light. The more intensity, more blocks will reach.
: It might be interesting to work out what sort of intensity function is being used.
Fade 2, I'm not certain of.
RG said it was the number of "sectors" selected for the light
to "travel" (also, it depended on "good tastes" )
: : RGB Values (it is with that I work) - The lights of the rooms you can usually use the values R for red, G for green and B for blue, but to Spot Lighting you need " to invert " the colors (you can use Paint to make that).
that's correct for TR3...
: [a lot of stuff on inverting color values]
: Seems weird.
yes, but nice! I goofed w/ TRitems lights for a week or 2 when
Roy first brought them out many moons ago...
it's possible to even get clever enough at it so that you can ...
mimic a pink-colored light on the "South" face of a collumn &
have a blue-colored shadow on this collumn's "North side"
kool effects! (but, very time comsumming...)
