2D and 3D Techniques

Lesson 1 in Intro to 3D Concept Design

Lesson Information

Deciding which dimension to work in is a tough choice. To start things off, Jama will walk you through the advantages and disadvantages of using 2D vs. 3D, and the power of combining them together. We will then do a tour of 3D-Coat, including the tools and workflow Jama uses to create concept sketches.


1. Starting from silhouttes, create a futuristic cityscape. Try using different shapes from study to build a nice variety creating your own unique shapes.

2. Take those unique shapes and paint height maps

3. Render and texture your setup in Keyshot

Hi Sebastien,

very very good start.. absolutely love the angle and story telling.

Z-depth is rendered in 32-bits...if it looks white..all you need is to play with Exposure.. image>adjust>exposure..
move a slider..and you will see the value range.

Hope it helps
looking forward to seeing more stuff from you!

Hi Sathish, thank you very much for your feedback ! Though to my surprise, I have rendered the zdepth pass. It didn't do much once in photoshop, it was just a complete white pass with a black spot on top. Maybe I did something wrong in the process... I'll be adding fog then :)

Updated : alright guys, my problem seems to be solved, mainly due to orthoscopic view :-)
thanks anyway

Hi everybody, I'm new here, I've just started the first homework this morning though I already need your help!
I have this problem with 3D-coat when I extrude from the stencil I get this result (see picture) .I extrude with the lasso. I am using Jama's stencil so this shouldn't be a matter of grey values... And there are those cracks appearing on my own buildings too, even when I cut off some forms, it appears quite soft, like round shapes. I am lost here....

Some input: The fog/clouds is a bit misleading here. As already noted the perspective is not very dynamic at the moment, which results in a flat look. The fog even increases the flatness, because it is just on top of everything. Real fog also has a view distance - so objects in the foreground should be more visible. The image would be more dynamic if on of the bigger buildings wouldn't be totally covered in fog - it's also a great way to lead the viewers eye. The Blade Runner intro is a good example:

Hey buddy good start....few critique hope that would ur image looks flat...and no variation to the building height.....and also play with ur stencils shilloute a little bit further...and also work on ur composition...go more dynamic angles like Jama said,,thats the main purpose which we are bringing into keyshot to play with camera angles.....also render zdepth pass for atmospheric effects......hope this will help u buddy...good work.

Hey guys - just joined and wanted to say hi. Just got started yesterday with the first chapter and got totally carried away after learning the first couple of tools. It's such a relief to ignore stuff like mesh-flow and be able to just experiment with shapes. My tool-tests resultit in this little tank-thingy, which I put in Octane with a procedural material for testing. Excited to continue and do the homework!

I had this same problem. I solved my problem by going into Photoshop and color picking my stencil. The stencil needs to be solid colors. So, even though the grey chunks of the stencil looked solid, it was actually varying very slightly. For instance, I color picked a solid block and I was having variation between a5a5a5 and a6a6a6. So, to fix this, I made sure the brush tool was 100% opacity and 100% flow.

Hey everyone!
Superlate on the assignments, but I'm trying to push on as much as possible. I had a blast this week, this method of working is really fun and intuitive.
Here's my week 1 image, I was going for a de-saturated / winter-ish cityscape at dawn (winter is coming, don't forget). With some random jets flying around for scale. C/C is welcome. Cheers!
