Southern Pacific's Coast Daylight 1937: GS-3 4-8-4

LoganTMT

Hello everyone,

My name is Logan Thurman and recently I've started a new 3d modeling project. This project is based on a prototype Locomotive that will be developed for an Unreal Engine animation project in the works. I'm building this for a very detailed high end game that I've been planning for about the past 3 years, but now the first part to it have officially been started and mostly completed.

The first stage of my project is to get the Locomotive built, rigged with animated suspension and start the first stages of the map design built(Positions will be posted soon). And I aim to get the Southern Pacific GS-4 4449 sounds recorded to specifically match the 3d model GS-3.

[These are the original builders drawings for the locomotive]




[This is the first wheel for the highpoly model]


Thanks,
Logan Thurman

Goodluck getting all the pieces the right sizes. Fudging the animation and/or physics usually helps with this sort of project

Here is some work on the Lightweight Boxpok Driver I've done today.

LoganTMT

Completed the Heavy and Light Drivers and now will do the intermediate Driver.

LoganTMT

Completed all three wheels and now Ready to place in frame.

Here's the model so far with the wheels added to one side.

Nice start could you show a bit more the frame? Tried to modelize a steam train kinda long time ago and i always found the frame plans difficult to read

LoganTMT

They aren't that hard actually. the way a frame is designed is in two variations. Built up(Pre 1930) or Cast one piece(1930+) I can tell you right now, the frame has to be rebuilt since this is from the original model before I realized It was incorrect.

First successful attempt getting the mesh in UE4.

Great detail in your models, looking forward to your updates

LoganTMT

Got the steel tires on the drivers now.

Some more work on the new and improved locomotive bedframe, and a few textures to see what this model would start looking like.



Thanks,

New Render with new materials on Main Driver.

Critiques Welcome.

Made some Spline rail in Unreal Engine 4 for my model to sit on. Now I just have to figure out how to do the Railroad Tie Textures.

LoganTMT

Here's my current progress on the Smokebox front.

LoganTMT

Got the boiler and firebox built.

LoganTMT

Testing textures in Unreal Engine 4.

Olingova

Slowly coming along! I already tried to make a train locomotive back in the days and i always lacked of reference for the inside; did you get some?

LoganTMT

I have the entire locomotive including a photo of the cab interior.

LoganTMT

Finally figured out how to build the Skyline casing to follow the actual versions used on the SP GS-3.

LoganTMT

Did some animation of the rods of the locomotive and built new side skirts for it.

OH nice! Please continue. I would like to see the process of making something so complex.

Olingova

Nice!! Any chance to see some close ups of the wheels suspension? Look forward to see the cabin, should be interesting

LoganTMT

The Suspension won't be modeled until I can get the frame and Cylinders built, but I need to get the builder's drawings of it first.

LoganTMT

Latest Texture Test for the Locomotive so I can get an idea of the colors.

MarcoAntonio

mmm... Try to finish the base mesh first. Then make a HP and after that you will decide how you will handle texturing. A mesh like this may need more than one texture.

LoganTMT

I have to only import certain things in cuz otherwise my Substance Painter crashes.

LoganTMT

I'm starting to like the red and orange on this engine. Very nice...Now need to do some aluminum stripes between the red and orange.
