Steampunk Vehicle Challenge_"Blowing Off Steam"

Recommended Posts

steampunk_03BWx.jpg

Hello all, let's see if I can finish on time.

My concept attempts to combine several different vehicles into one ultimate steampunk machine.

 

I will try to show you how I created a lot of the parts in 3D_Coat.

Creating wheels in 3D Coat.

As with most things there are several ways to go about making stuff in 3d Coat, here I choose to revolve or "lathe"a train wheel by using a profile segment and the axial tool.

Creating Spokes:

To create the spokes I start with a box primitive and shape it using the cutoff tool.

Once the the profile is created, I drag it to the splines tab, and convert it to a curve profile.

I then choose a cylinder primitive and voxelize it to be used as the center hub for thespokes.

With the cylinder selected I choose my spline profile segment and use the curves tool

with radial symmetry to make the spokes.

Creating the steam dome and whistle

Again starting with basic primitives I rough in the forms

I use a combination of the pose tool and cutoff tool to refine the shapes.

Using smooth with radial symmetry helps refine the forms.

Using the E-panel spline tools makes it easy to create more complex forms.

After entering the paint room I apply smart materials and use custom alphas for further detail.

Creating the Sandbox dome

Old steam locomotives use sand sprinkled on the tracks for added traction.This container sits on top of the boiler to help heat and dry the sand.

Same basic techniques as previous.

Nice! and many thanks for taking the time to make these how to's pics!

(It never occured to me before to use a high radial symetry for smoothing, for example. Neat trick)

Smoke Stack

If you're gonna smoke do it outside.

Using the Lathe tool located in the primitives tab.

If you need a "hollow tube" you need to double up on the points.

Chassis

Carrying the load

To make the chassis, I download some blueprints online and drag them to the Stencils tab.I then create a rectangular shape from a primitive cube and voxelize it. Then increase res. to 8x.

I click on the blueprint stencil and use the extrude brush with the rectangle lasso in the E-panel to transfer the depth of the image to my voxel object.

Then using the cutoff tool I define the shapes.

I add some leaf springs and support brackets, as well as a test wheel.

Pilot (Cowcatcher)

In railroading, the pilot (also known as a cowcatcher or cattle catcher) is the device mounted at the front of a locomotive to deflect obstacles on the track that might otherwise derail the train.(wikipedia)

Pretty self explanatory for this one.Used the pose tool to bend the main frame.

Cut out one support bar and copy, adjusting with the transpose tool and the pose tool till everything is in place.

Tanks and Hoses

Not sure what these do, maybe bleed moisture out of the system?

Mainly curves and cylinders detailed with the extrude brush.

@tree321:

Will you be able to finish modelling your entire project in time for August 10, 2016?

Even if you don't finish in time, I have to say this step-by-step documentation of your modelling process is pretty awesome and deserves special merit.

Thank you AgentSam, I appreciate you stopping by.

I have actually finished the project for the most part, but thought I'd take the extra time to make this a process tutorial as well.I know there are a lot of new users who could probably benefit from these tips.

Take care!

Ship Hull (actually a submarine hull)

What? A ships hull?But I thought you were making a train.I must have lost my train of thought.

Well I originally made this model for another contest some years back and thought I'd try to replicate it in 3D-Coat,but I'm not really happy with the results.

I layed out the original forms in voxels, then retopoed it and tried to use the retopo tools to define it, but really the low poly modeling tools need more robust features for this model.(or I just need to figure them out). Anyway... I think I will just use the original low poly mesh for this piece.

Submarine turret/Bridge

This submarine is based off the nautilus, from the movie 20,000 leagues under the sea.I have scaled it down to fit my composition

Tree

...only God can make a tree

But this is good enough for me

. I think that I shall never see
A poem lovely as a tree.

A tree whose hungry mouth is prest
Against the earth's sweet flowing breast;

A tree that looks at God all day,
And lifts her leafy arms to pray;

A tree that may in summer wear
A nest of robins in her hair;

Upon whose bosom snow has lain;
Who intimately lives with rain.

Poems are made by fools like me,
But only God can make a tree

Joyce Kilmer
