Hello,
I have trouble getting the lighting right for an outdoor scene. I use an HDR
sky, radiosity and a ground plane. In this image, it appears that the sky casts
light onto the box from the left, but there are no shadows.
Also, the white plane is too dark.
The HDR sky is https://polyhaven.com/a/lilienstein. The relevant part of the
code is
global_settings {
radiosity {
pretrace_end 0.001
count 500
recursion_limit 1
low_error_factor 0.2
brightness 1
}
}
sky_sphere{
pigment{
image_map{ hdr "sky.hdr"
map_type 1 interpolate 2}
}
}
box {
<0,0,0>, <8,8,8>
pigment {rgb <239, 204, 148>/255}
}
plane {
y, 0
pigment { White
}
}
