I'll give it a try after dinner, I must leave now. But..

At the third line, isn't there one extra parameter there? I mean, what does
that last 5 mean? If I'm not missing anything that may be causing problems,
and I've seen it in all your materials... I'd remove that last figure from
there and give it a try that way. Like this:

MATERIAL Material0
0.0627451 0.156863 0.180392 0.2
0.192157 0.47451 0.545098 0.2
0.898039 0.898039 0.898039 0.2 25
0 0 0 1

This is what Orbiter's doc say on this matter:

MATERIAL <mtrl-name> material header
<dr> <dg> <db> <da> Diffuse colour (RGBA)
<ar> <ag> <ab> <aa> Ambient colour (RGBA)
<sr> <sg> <sb> <sa> <pow> Specular colour (RGBA) and specular power (float)
<er> <eg> <eb> <ea> Emissive colour (RGBA)

The power values I'm using range from 10 to 20, the higher this value, the
broader the light cone will be.

Also, before converting the mesh to .msh format, place the transparent
material in the last position of your materials in the modelling package
you're using. I've read somewhere that the transparent materials should be
placed last although I'm not sure about it, it sounds strange to me but it
may be worth giving it a try.

I'll let you know if I manage to get it working.

Regards
