Here I am again, pleading for help. I wonder if I'll ever learn enough that I
can stop having to ask simple questions...
This time the part won't show up, rather than the part showing up, um, *too*
well. I'm working with that transparent sceptre again you all helped me out with
a few weeks ago. Now it's almost 100% clear and nothing I do seems to change it.
With this code:
#ifndef (Color47)
#declare Color47 = #if (version >= 3.1) material { #end texture {
pigment { rgb <0,0,1> #if (QUAL > 1) filter 0 #end }
finish { ambient AMB diffuse DIF }
#if (QUAL > 1)
finish { phong 0.5 phong_size 40 reflection 0.2 }
#if (version >= 3.1) #else finish { refraction 1 ior 1.25 } #end
#if (BUMPS) normal { BUMPNORMAL } #end
#end
} #if (version >= 3.1) #if (QUAL > 1) interior { ior 1.25 } #end } #end
#end
I get this image (I'm using a Q1 setting):
http://www.brickshelf.com/gallery/Buachaille/Raytracing/scepter.bmp
Sorry the image is so small - it's late at night again and I want to go to bed,
not wait all night for a larger image to render.
Anyway, the sceptre is supposed to be in the white hand. If you blow the image
up, you'll see a (very) faint white outline. The problem is that no matter what
I change (the RGB value originally was <1,1,1> and the filter, though apparently
unused, was .85), the scepter color doesn't change - doesn't get fainter and
doesn't get stronger. Doesn't even change hue!
What am I doing wrong? Another "quirk" like the last one? Help!! :(

| Hi Mike, I doubt it's the material definition you posted. It renders as a nice solid blue on mah machine. I have blown up the image and seen what you mean. It sure looks like a transparent material has been applied to it. ? (21 years ago, 4-Mar-04, to lugnet.cad.ray)

| (...) I've played around with this a bit and I think what is happening is that you're trying to accomplish several things at once, and some collide with others. By setting the transparency and transmit values high, you're bascially instructing the (...) (21 years ago, 3-Mar-04, to lugnet.cad.ray)
