Hi,
I am having more texture difficulties that I cannot workout..
The only difference with the two images below is the addition of a box
with a glass material which is behind the other box. Somehow this is
adding some very odd highlights to the object in the foreground.
The full source for this problem is:
#version 3.7;
global_settings {
assumed_gamma 1.0
}
// focal blur camera
camera {
location <0.65 , 2.5 ,-4.0>
// location <0.65 , 12.5 ,-14.0>
look_at <0.725, 2.1 0>
right x*image_width/image_height
aperture 0.005 // [0...N] larger is narrower depth of field
(blurrier)
blur_samples 100 // number of rays per pixel for sampling
focal_point <1.0,2.5,0.4> // point that is in focus <X,Y,Z>
confidence 0.95 // [0...<1] when to move on while sampling
(smaller is less accurate)
variance 1/2000 // [0...1] how precise to calculate (smaller
is more accurate)
}
// An area light (creates soft shadows)
// WARNING: This special light can significantly slow down rendering times!
light_source {
<0,0,0> // light's position (translated below)
color rgb <1, 1, 0.9> // light's color
// area_light
// <2, 0, 0> <0, 0, 2> // lights spread out across this distance (x * z)
// 4, 4 // total number of lights in grid (4x*4z = 16
lights)
// adaptive 0 // 0,1,2,3...
// jitter // adds random softening of light
// circular // make the shape of the light circular
// orient // orient light
translate <-6, 8, -10> // <x y z> position of light
// light_source { ...
// put this inside a light_source to add light fading
}
