Alien gun concept

In this tutorial, I’ll show you the final step to set up the ZBrush concept of an alien gun for rendering in Keyshot. To illustrate the simple workflow, I’ll use a ‘Sci-fi box’ but the exact same process can be applied to more complex objects. The first 3 parts of this series are #ZBrushLive streams sessions

PART 1 – Blocking out the concept

The first 3 parts of the series are recordings from live stream sessions from #ZBrushLive

In this episode, we’ll set up the primary shapes of the alien gun based on a quick thumbnail sketch. I’ll walk you through a simple technique to ‘trace’ geometry over a reference image to generate geometry.

Using the SnapShot 3D feature in ZBrush 2019 could be an interesting alternative to the process I used in this first part.

PART 2 – Refining the sketch

In this second step of the process, we’ll start to use Dynamesh and fine-tune the shapes and volumes.

‍

PART 3 – Adding details and custom alphas

In this third part, we refine some of the sketch transition and polish the surfaces. We’ll re-build the ‘plasma cylinders’ from scratch and create custom alphas with a simple, yet powerful, technique using a cube, Live booleans, insert meshes and the GrabDoc button.

Final concepts / renders

Below are some extra images of this project and the sci-fi box. The images (decals) I used to texture the final gun and the sci-fi box in Keyshot are a great Sci-fi pack from Munkhjin Otgonbayar that I bought from his ArtStation.
