What's this, Griff - you got a top hat now? Very snazzy!
I would advise stilts for the quagmires, and camels for the snowy hills
And any survivors, their debts I will certainly pay. There's always a way!

As it looks like no one else has said it yet... That's a(nother) great looking model Griff.

The Sidewinder was always one of my favourites and your tribute to the original distinctive shape combined with fine yet distinctive detailing works really well. Kudos.

As for the colour scheme, what were you thinking? :shock: (just kidding :P )

thanks for the kind words Redspear, i've been picking away at it for ages, it's the first model that i've successfully 'baked' some of the highpoly details from into a normal map, i tried earlier with a cobraIII model and it was a distaster, but it seemed to work OK with this one. Plan with this is to get it looking great with Oolite's Materials then try for shader version just for the engine glows and decals and stuff

@Cholmondely
It's more like a tube of crepe paper shaped into a hat i think :D

The original grayscale diffuse map
Added
monocolor ( yellow fill ) spec map with

Because you have created an impossible material and because Oolite's lighting model complies with light energy conservation.

Only metals can have colored specular in nature and, as we know already, if you have a metallic material then you need to provide a black diffuse map. You are providing a non-black diffuse, therefore you are creating a material that cannot exist in nature.

Still, Oolite tries to apply physically based lighting that conforms to light energy conservation to that impossible material. In doing so, it creates a specular reflection with the inverse of the color you have provided in the spec map. If you are providing a yellow specular, that inverse color will be blue.

Solution: Avoid invalid materials.

When using the new materials system does / should

"smooth" = no;

Still work for light and shadow(s)?

I don't see why it shouldn't. Lighting does not depend on the mesh it is applied on.

Well the shadows do make the model look better, perhaps I expected the shadows 'harsher' pronounced...

Any chance of a decal function for the new and improved materials system?

The original gsagostinho textures had that nice lacquer paint look,
is it possible to recreate that with the improved lighting and materials system?

I'm still looking for what OXP/OXZ that station can be found in...

cbr was good enough to create an oblong version for Xeptatl's Sword as an updated version of the monitor station. But we were looking for something which was less obvious and disguisable as an asteroid or some such (fitting in with Smiv's original concept), and are thus stuck with the shrunken Jaguar Company station with the too-tight docking tunnel... :oops:
