Hi,
after the encouraging comments on my Breal WIP I changed several things.
in my last WIP before final render Povray showed an unexpected result.
I marked two parts of the picture and included two enlarged detail renders
of these parts.
The third detail render shows the same location and is apparently ok.
In this version I substituted different tree types to show only the same
tree type (like in the version I showed already).
Max_trace_level was set to 200 (Max Level was 82 for a smaller test render).
I used Poseray 3.01 for the conversion of the 3ds trees to pov formate; the
texture definition is always like this:

#declare p_map4=pigment {image_map{png "tex.png" interpolate 2}}
#declare p_map5=normal {bump_map{png "tex.png" bump_size 3 interpolate 2}}

#declare leaf_tex1=
texture{
    pigment{p_map4}
    normal{p_map5}
    finish{specular 0.8 roughness 0.005 ambient 0 diffuse 0.5}
}
#declare leaf_tex2=
texture{
    pigment {color rgbt 1}
    finish{ambient 0}
}
#declare leaf_tex=
texture{
    image_pattern{png "tex_alpha.png"}
    texture_map{
        [0.0 leaf_tex2]
        [0.9 leaf_tex1]
    }
}

The new trees, which obbiously cause the problems, are included as mesh2
files, the first tree is a normal mesh.
The hole scene takes nearly a GB of peak memory, the bug is the same on a P4
XP sytem with 1 GB RAM and on a Athlon-System with WIN2000 and 1.5 GB RAM.
The bug show up at Megapov 1.0 and on 3.5.

Can somebody help me, please?
