Winning entry of Weekly CG Challenge 108 “Steampunk Device” by Lautaro Iglesias


1. Tell us a little bit about yourself: Who are you, what do you do, and where are you located?

Hi! my name is Lautaro Iglesias, I’m 24 years old, living in Buenos Aires, Argentina. Once I was an industrial designer student, a graphic designer student later on, and now I am just a 3D guy, who loves everything related to the CG world and tries to make a living out of it.

2. Where did you find the inspiration for your latest entry?

At first I was not inspired at all. I like the steampunk style but I didn’t have any idea for the challenge itself. Then i saw a vintage grand prix car and I thought that it would be a cool idea to make a steampunk version of it mixed with a steam train system/engine. Once the concept was defined I went to pinterest and started looking for references (119 to be exact).

3. What software and plug-ins did you use to create this image?

I used mostly Blender 2.79 and a little bit of Photoshop just to add some particles. Most of the post processing was done in blender.

4. Can you give us a short breakdown of your entry?

Once I had the idea, I started directly to model the first car. I did not do sketches or anything. This is not recommended, but I already had a clear idea in my mind and a lot of references so I skipped that step.

fig.1 Pinterest references

fig.2 I watched a video on youtube that shows how a steam locomotive works. It was very helpful to
know which parts of the train I need to add and how to integrate them.

The rest of the scene was really improvised. I added some landscape and trees PNG for the background and I built a fence between the cars and the horizon line to integrate both parts.

For the compositing I used the classic tricks: Glare, lens distortion, chromatic aberration, vignette effect, sharp filter, and the mist pass. Then I added some particles in Photoshop and that’s all.

fig.4 As you can see, the wheels are not even connected to the rest of the car! Here’s a tip: don’t work more than necessary.

Then I set the camera in position to start looking for the best way to compose the image and added some steam textures and lighting.

After that I began working on the second car. At first it was going to be very similar to the first one but I was very motivated (I guess) so I decided to make an aircraft style car instead. I knew most of the car was not going to be seen by the camera, so I just modeled the parts that were to be seen in the final image.


fig.3 The steam are just PNG images. The materials were made using the principled shader and some free textures from The railroad was just a reference at this point.

fig.5 I parented the cars and the camera to an animated empty to generate the motion blur.

4. Any advice for people who want to learn 3d art?

My advice to anyone who wants to learn CG is to look at every tutorial that you come across and then start simple projects that you know you can finish. A win project! That way you will always be motivated to continue learning and challenging yourself.

Thanks for the interview Lautaro!
