Ok, open to suggestions. What on the art front has you stumped? Lofts? Track? fancy train shaders? animations or just some hints tips on modelling?
Feel free to request.

How to make a Platform light with emmisive glow
In the route of your ‘Provider’ make a new folder called Lights. This is where you will keep the
max, igs and xml files.
In the Lights folder make a Texture folder. This is where you will keep your textures
Step 1: Gizmo
creation
We need to make a Point light gizmo.
This is what we will use to determine where the light
effect gets generated from. This gizmo you will be able to move around in the
Asset editor.
I have made a 30cm Diameter sphere with a Tex material,
the texture is a bright pale yellow, 64/64 pixels, planar mapped from the top.
This I centred at 0/0/0 in max.
Export this into a igs file.
point_light.IGS
Step 2 Make the
point light xml.
Right click the point_light.IGS in the asset editor and
click new shape blueprint and select point light blueprint.
Treat this just like any other scenery object, name it in
the relevant fields, and give it a provider product in Primary named texture
set.
In the light component section give the light a radius, I
have given mine 10 (M)
Give your light a colour, I picked a warm yellow/orange.
Click Save.
Preview your shape and you will have your object in front
of you. Click the Day/Night cycle button in the top left flyout menu. Your
object should glow (because of the tex material)
Select your object and lift it up in the scene. You will
see that it now emanates light. Experiment with the light and radius values to
get the desired effect you want.
Step 3: Light
Asset Creation.
There will be at least 3 objects in your scene but 5
materials:
Objects in scene:
1_0500_LampPost
1_0500_bulb_day
1_0500_bulb_night (with Forward facing glow element)
I have a 4th object which is the glass.
1_0050_glass
Materials used:
Material 1 used on
1_0500_LampPost. It can have any material you want, I have a
TrainBasicObjectDiffuse. It uses 1 256/256 texture which I boxed mapped.
Material 2 used on 1_0500_bulb_day. It can have a tex or
a TrainBasicObjectDiffuse. It uses 1 32/128 texture which I planar mapped.
Material 3 used on 1_0050_glass. It has the Trainglass.fx
shader explained in a previous blog post.
Material 4 used on 1_0500_bulb_night This uses the TrainEmissiveGlow.fx
shader
In the sub material slot 1 I have a diffuse texture very
much like bulb day texture. However I colour the bulb section yellow (this is used
for the colour of the glow) Name this texture Bulb.ace
In the sub material slot 2 (making sure the same UV
channel is used (1)) I have a texture that is the same size as my bulb texture
but it is black and white. The white area defines the glow area, the black is
the non glow area. name this texture with Bulb_EM.ace
There is a second element (but part of the same object) to 1_0500_bulb_night
which is a simple plane centered through the bulb.
This plane uses material slot 5 which is AddATex. The
texture is all black except for a faint glow in the centre. make sure you name this with _nm so that it does not get compressed.
This material has the View facing flag ticked under the
Viewer Facing options.
Save the max file and export as an IGS, I called mine Platform_light.IGS
NB The bulbs are named so that the day bulb will show during
the day and the night bulb will show at night.
Step 4: Bringing
it all together.
In the asset Editor right click the platform_light.igs
and select New shape blueprint, then select scenery blueprint.
Preview shape, you lamp should be as you expect it. Click
on the day/night button and see your bulb glow.
Name the relevant fields, and give it a provider product
in Primary named texture set. Expand Children and click insert first.
Give the Child name/provider product and select your
previously made point light and click preview.
Your point light orb will be at 0/0/0 select it and move
to the correct place.
Click Save and Export.
Your light should now be viewable in game.
