Something very wrong with exporting to POV-Ray. An object containing
different image_maps, uv_mapped, and with transparency maps is exported
with really /basic/ material settings, ignoring the details present in
the original. Additionally, the transparency maps are /not/ exported. I
don't konw about normal maps but I advice that should also be investigated.
/Al/l materials of the object have now the following appearance, which
was not so with earlier versions of Poseray. Examples with first version
3.13.22, followed by version 3.13.19 which gives the correct build for
the same material:
//==================================================
#declare ZIS5ligh_=
#declare PR_DIFFUSE=pigment{p_map3}
#declare F1=finish{specular albedo 0.8980392 //Max highlight intensity:
0 -> 1
roughness 0.1706121 //surface roughness: 0.0005 -> 1
phong albedo 0 phong_size 0 //Phong specular disabled
ambient <0,0,0> emission srgb <0.10,0.10,0.10>
//ambient RGB color: 0->1 for each component
diffuse albedo 0.6
reflection{0 } conserve_energy //reflection amount:
0 -> 1
}
#declare T1=texture{
pigment{uv_mapping PR_DIFFUSE }
finish{F1}
}
material{
texture{/*uv_mapping*/
T1
}
}
//==================================================
#declare ZIS5ligh_=
#declare PR_DIFFUSE=p_map4;
#declare F1=finish{specular albedo 0.8980392 //Max highlight intensity:
0 -> 1
roughness 0.1706121 //surface roughness: 0.0005 -> 1
phong albedo 0 phong_size 0 //Phong specular disabled
emission srgb <0.10,0.10,0.10> //ambient RGB color:
0->1 for each component
diffuse albedo 0.6
reflection{0 } conserve_energy //reflection amount:
0 -> 1
}
material{
texture{uv_mapping
pigment_pattern{p_map5 translate<0,0,0> scale<1,1,1>
translate<0,0,0> rotate<0,0,0> translate<0,0,0> }
texture_map{
[0
pigment{color rgbft<0,0,0,1,1>}
finish{ambient 0}
]
[1
pigment{PR_DIFFUSE translate<0,0,0>
scale<1,1,1> translate<0,0,0> rotate<0,0,0> translate<0,0,0> }
finish{F1}
]
}}
}
//==================================================
I agree with the suppression of all the redundant transformations but
more is at issue here!

It is working fine here. Maybe you have a material combination where
PoseRay fails. Could you show me the entry in the mtl file for the above
problem material?

From the obj version of the object:
newmtl Lights
Ka 0.0980392 0.0980392 0.0980392
Kd 0.807843 0.807843 0.807843
Ks 0 0 0
Ns 1
map_Kd C:/Users/.../ZIS5_L_ZIS5NET.JPG
The same happened with the original 3ds version by the way.

Reconsidering the issue, I think the issue arises when exporting the
materials to POV-Ray. Taking another material as an example, the
screenshot below shows the material screen used. Export results in the
following POV-Ray materials. For Poseray version 3.13.19:
//==================================================
#declare ZIS5503_=
#declare PR_DIFFUSE=pigment{pigment_multiply(p_map4,pigment{color srgb
<0.70,0.70,0.70> })};
#declare F1=finish{specular albedo 0.8980392 //Max highlight intensity:
0 -> 1
roughness 0.2401081 //surface roughness: 0.0005 -> 1
phong albedo 0 phong_size 0 //Phong specular disabled
emission srgb <0.10,0.10,0.10> //ambient RGB color:
0->1 for each component
diffuse albedo 0.6
reflection{0 } conserve_energy //reflection amount:
0 -> 1
}
material{
texture{uv_mapping
pigment_pattern{p_map5 translate<0,0,0> scale<1,1,1>
translate<0,0,0> rotate<0,0,0> translate<0,0,0> }
texture_map{
[0
pigment{color rgbft<0,0,0,1,1>}
finish{ambient 0}
]
[1
pigment{PR_DIFFUSE translate<0,0,0>
scale<1,1,1> translate<0,0,0> rotate<0,0,0> translate<0,0,0> }
finish{F1}
]
}}
}
//==================================================
p_map4 and p_map5 being respectively the pigment and the transparency maps.
For Poseray version 3.13.22, the export looks like this:
//==================================================
#declare ZIS5503_=
#declare PR_DIFFUSE=pigment{p_map3}
#declare PR_DIFFUSE=pigment{pigment_multiply(PR_DIFFUSE,pigment{color
srgb ((<0.70,0.70,0.70>-<1,1,1>)*1+<1,1,1>) })}
#declare F1=finish{specular albedo 0.8980392 //Max highlight intensity:
0 -> 1
roughness 0.2401081 //surface roughness: 0.0005 -> 1
phong albedo 0 phong_size 0 //Phong specular disabled
ambient <0,0,0> emission srgb <0.10,0.10,0.10>
//ambient RGB color: 0->1 for each component
diffuse albedo 0.6
reflection{0 } conserve_energy //reflection amount:
0 -> 1
}
#declare T1=texture{
pigment{uv_mapping PR_DIFFUSE }
finish{F1}
}
material{
texture{/*uv_mapping*/
T1
}
}
//==================================================
p_map3 is the pigment map but the transparency map is /not/ exported at all.

Found it!
In POV-Ray Output/Scene: Check the 'Use material transparency' box.
I overlooked that one!

That is an option I added for quick test renderings. I added other
options for quick test renders and a SSLT workaround for some DAZ Studio
models. Anyway, I did find a critical bug in the partial POV-Ray code
parsing, and the manual was incomplete so I uploaded a newer version.

I noticed the incomplete manual too. Thanks for your fine work btw!
