A long time ago, Jeroen kindly rendered this image for me in POVRay
http://miltontrainworks.com/MTW/images/MTWproductLine_1280x1024.jpg
But the source got lost. Now I need it much much larger so I'm trying to
recreate it. I am all the way there (all models positioned right, etc) except
for the lighting/shadows. Which may well be the hardest part!
I like how the shadows are, they are relatively light. I also like how the base
reflection is set up (i.e. there is none)
I've been trying a lot of different render settings and surface settings but I'm
either getting large muddy shadows, or I'm getting a surface that reflects the
models. Anyone have any clues on the best combination of surface materials (for
the white plane that everything sits on) and light source settings? I thought
maybe an area light was the way to go but it's not working well for me.
Here's my current surface settings...
texture {
pigment{ rgb <1,1,1> }
finish {
reflection 0
ambient 0.4
diffuse 0.5
roughness .01
}
}
Am I even on the right track there?
Thanks for any suggestions.

| (...) Hi Larry, I'm not much of a POV expert, but it looks to me like Jeroen used a single light source (I only see one shadow per model). I'd guess the light source is very far away (to simulate sunlight) because all the shadows cast proportionate (...) (13 years ago, 2-Jun-11, to lugnet.cad.ray)

| It looks to me like each model / row of models was rendered in POV-Ray individually and then PhotoShopped together. Probably removed any reflections when combined on to one image. Scott (13 years ago, 2-Jun-11, to lugnet.cad.ray)

| (...) Looking at the lighting, I'm pretty sure he used radiosity and prolly his FastRad library. I might still have a copy lemme poke around. -Orion (13 years ago, 2-Jun-11, to lugnet.cad.ray)

| (...) --snip-- (...) To take a stab at it: * The light is very high. You'll have to tweak its angle. * If you use an area_light you'll probably get the soft shadow edges * Reflection is turned off or very low * The ground has a fairly high ambience, (...)
