Hi Coyotek,
I've been looking over your lovely 111a (and variants) and have some feedback.
1. The bogies are vanishing too quickly using LOD. They are vanishing at 99%. This may be something Pitek did when he imported them into Unity
2. We models need to have no windows from LOD2 onward, otherwise it's too computationally expensive to draw those features when you can barely see them. Could you please drop this LOD down to a box with *slightly* rounded edges at the top
3. They could use some individual window panes (use the glass_01 mat in Unity, this is the same glass as on the signalbox) rather than one long strip. The glass panes don't need to be in LOD2
4. If you could make the doors on the ends of the carriages look like mine, that would look much better
5. Do you want to do a specular map? This will make the carriages look shiny. If you don't want to make one, I can do one, but it'll have to wait until I've finished something else
Other than that, these look great
With these changes, they'd look great in the new version
