In this lesson, you will learn how to create a Sci Fi Panel Generator for use in game engines such as Unity. This will be a high level tool that artists can use to quickly turn designs created in Adobe Photoshop into 3D panels for use in-game. As a technical artist, you will learn how you can build this kind of tool using Houdini's node-based workflow including a range of specially designed GameDev Tools published by SideFX. 


All the nodes and networks will then get wrapped up into a Houdini Digital Asset or HDA which can be loaded in Unity using the Houdini Engine plugin. Once the tool is ready, game levels can be quickly set up using using this generator tool and some source Photoshop designs to create quality game art.


INTRODUCTION

This overview shows you the finished asset and its various controls work in both Houdini and in Unity. You will learn what kinds of parameters are available and how you can turn a Photoshop file with multiple layers into a quality game-ready model.

PART 1 | MODELING THE PANEL

In this lesson, you will start with the Trace PSD GameDev tool then use that to start modeling the various layers of the panel. You will learn how to place the parts in relation to each other and will make sure you set up your nodes procedurally so they can handle different PSD files with unique designs.

Length: 33:43

PART 2 | ADDING DETAIL

Now that the main body of the panel is ready, you will learn how to use more layers in the PSD file to add details such as grooves or to place existing pieces of detailed geometry. You will then set up both high and low resolution versions of your panel to allow for texture baking in the next video.

PART 3 | CREATING THE DIGITAL ASSET

It is now time to wrap up the nodes and networks into a Houdini Digital Asset or HDA which becomes a high level tool for artists to work with. You will promote parameters from key nodes to build an interface for the tool and then you will test it in Unity to show that it is ready for level builders to use to lay out the game.

Length: 37:21

NOTE: The controls available on the Houdini Digital Asset are available in the game editor. The results are baked when the game is compiled and the procedural controls are not available at runtime.

    Just in case someone face the same problem as me, you need to update your GameDev Tools to a non production build (1.203 worked for me).

    Otherwise you might not see the "layers to extract" option within the trace PSD file.

    Wow! Good Work! Its very nice!!

    Great work mate

    The geo generation works for Me, but the Normal Map baking is not working.
    I've upgraded to 17.5.391 and the GameDevTools to version 1.203.
    Does this work with the Indie edition or is there an additional step that I'm missing.
    This is a great tool. Any help would be greatly appreciated.

      Here is a video showing issue:

      Again, the geo is being generated, but the Normal Bake only generates a blue texture with no elevation in the Normal Map.

        Now using the simple baker and able to get the normal's exported.

          In case you still wanna use the Maps baker (which I can recommend), here is a temporary fix.

          You place null nodes for the high and the low poly, then freeze the null node (which will store the data in the null nodes)

    Hello. I am new to Houdini. Is it possible to complete this tutorial with Apprentice version, combining Houdini & UE4/Unity?

    • Siver 2 months ago  | 

      The apprentice version doesn't include the plugin for the game engines. You will need to look at the Indie license, if you fully wanna use it. You could still build the tool but not open it in game engines.
      More about Indie license here https://www.sidefx.com/buy/#houdini-indie
      Or you can get also one on steam https://store.steampowered.com/app/502570/Houdini_Indie/

        Thank you for reply and this tutorial. It is a gift to get this sort of insight.

    Super Awesome!!! The workaround works a treat.
