(WIP)**GMD SD40-2 CP Rail**In Development from Searchlight Simulations

[BNSFdude]

There were essentially 3 CP schemes prior to NAFTA.
Large Multimark which covered the long hood from walkway to roof. It was the as-delivered scheme for the earlier 40-2s with the recessed shutter housing commonly called "chicken wire" radiators.
Small Multimark like Kevin showed, which was the as-delivered scheme for the later models with the externally mounted shutter assemblies commonly referred to as "corrugated".
Then there was the no multimark which many got repainted into.

Come NAFTA they had Dual Flags, post SOO full buyout (CP always had majority share) they had the Beaver on some, and of course they eventually changed the red to Candy Apple and put the boring logo on.

Will this be in the "pacman" scheme?

Yes.

Pac-Man scheme? Why is it called that?

This multimark logo was referred to as the "Pac-Man" logo when the game Pac-Man came out back in the 1980s.

Oh duh, I see these locos all the time.

Not to mention that CP's various orders each differed very slightly. Things such as radiator grills (which Anthony mentioned), blower housings, spare knuckles on walkway, and the list could really go on. They're very interesting locomotives to say the least.

No doubt they're very interesting, especially all the various paint coats the units recieved over the years of service. Every engine is unique and has it's very own character.

Let's not forget longtime Alco / MLW stronghold British Columbia Railway / BC Rail ordered 12 SD40-2s in 1980, built to CP Rail specs and another 5 in 1985, the only thing different were the paint they were delivered in. These were the only new EMD / GMD power ordered new by the railroad before turning to GE for all future new equipment due to Alco / MLW ceasing production. The railroad did acquire other used SD40s which it turned into "B" units with remote Locotrol equipment for DPU operations but were built to other railroads specs. It would great to see these CP Like units in two tone green or the red, white and blue hockey stick scheme too. I will be looking very forward to this release.

Since we're having a few issues with the export process of the trucks, I figured I'd show some new renders in the meantime.

Amazing work!

[OpenRailer90]

The attention to detail is great, just like the RailRight Class 40!

Finally got to swapping out the old axles with proper models.

This is looking great! What's preventing the export process?

[OpenRailer90]

The attention to detail is insane.

The trucks on any locomotive have to be exported as a single file in order for them to rotate based on the curvature of the track they're on. The exporter has a limit of what it's capable to export in a single file in terms of file size and unfortunately my trucks are simply to big to be exported in a single file due to all the details. Generally no big deal, however the trucks obviously have to turn when you go into a curve which requires a exterior animation and a script to trigger it. That's where I'm currently having issues at.

Normal mapping is your friend.

I prefer something "solid"

You may, but your users might not. Nuts and bolts are one thing, but a stack of washers is silly. Besides which, you're creating more work for yourself with multiple exports. FWIW, you can use the high poly models you created to create the normal map (nm). If you keep the parts using nm large, say 2048 x 2048, you may find that you can't tell the difference between the model and the nm.

It's a very nice looking model, and it would be a shame if it turns into a poly bomb. Anyone can throw polys at a project, but it takes some practice to create an efficient game-ready model.
