I have POV 3.02 and win 98. My PC has an ATI video card and 256MB of
ram. When I render a certain scene POV crashes most of the time with an
Invalid Page Fault in PVENGINE.EXE at 017f:something. Is this a bug?
How can I fix this? Here is the scene I'm doing.

Try changing your .bmp file to a .tga and use the code below. I tried to get
any .bmp file to work with my install of Pov v3.01r1 and could not get it to
accept it. Once I changed to .tga I had no problems. By the way if you are
concerned with backward compatibility you can install the newer version of
Pov into a different directory and run both versions. I have about 6 different
Pov versions and patches all running somewhat harmoniously together on my
system. There are some registry issues to contend with but they are not
insurmountable.
#declare earth_z = 60; //earth pos on z axis
#declare ast_z = -30;
#declare moon_z = -1;
box {-0.5, 0.5 // a unit sized box used for background image
texture
{ pigment
{ image_map { tga "galaxy.tga"
//interpolate 2
}
translate -0.5 // center the image to the box
}
}
scale <50,50,50> //make it bigger
translate <5,0,earth_z+10>
}

You speak like the keyword 'texture' in pov 3.0 has been replaced with
the keyword 'material' in 3.1. This isn't true, of course.
Moving all the ior-statement into the interior-block is not that tedious.
With pov 3.1 you get lots of advantages, like macros, faster lathes and
sors, etc.
