What's the color
Sometimes it can be a hard task to find out what the Transp.Col should be if you are
going to do clipmapping or scope masking. If you are going to clip 'off' the white part
of a texture, it is natural to enter 255 in the three gadgets that define the transparency
color. And it don't work!!! You’re so sure you did it right. Well, why run a paint
program and check what the color is, when there is a much faster method of checking
it?
- In the material editor, with the material you want to check colors from, set color
handler ro RPL, and enter this in the expression field: 'B FETCH G FETCH R
FETCH "R=" PUTS . "G=" PUTS . "B=" PUTS .'
- Make a very small render box in a place were you know the color is, and hit
'View/Render Boxes'. On PC it is best to have a infowindow open. Amiga is stuck
with 'ok requesters' unfortunately, so it is important to make the renderbox as small
as possible. A pixel would be enough actually as long as you know the color in
question would be in that pixel.
This method of readout can off course be applied to anything to check out what is going
on. As an example you could in scope RPL handler write 'relx FFETCH F.' if you want
to know the value on this at a given pixel.
