Coding in Unity: Mastering Procedural Mesh Generation (

Learn to procedurally program meshes in Unity, from simple shapes to complex terrain and infinite fractal landscapes.

Created by: Jenny Hide

Produced in 2022

What you will learn

  • Use Unity to generate complex meshes from code.
  • Create realistic looking landscapes with Perlin and fractal noise.
  • Program two and three dimensional shapes.
  • Procedurally generate meshes for both 2D terrain and 3D landscapes.
  • Use your knowledge of meshes to add vertex colours, and calculate UVs, normals and tangents.

Course Description

Learn how to procedurally generate meshes in Unity 5 to 2019. You'll start with simple shapes and work your way up to complex, fractal landscapes. This is a code-along style course where you'll learn how program meshes at each stage.
Learn, Understand and Master Procedural Generation with this Intermediate Unity Course.
  • Learn about the different properties of a mesh.
  • Create two and three dimensional shapes.
  • Calculate UVs, normals, tangents and vertex colours.
  • Understand how to use Perlin and fractal noise to generate 2D terrain and 3D landscapes.
  • Learn how to program large and infinite landscapes for you game.
A powerful tool for making games.
In this course, you will learn to procedurally generate meshes from geometric objects to worlds with randomly generated terrain. Many popular games use some form of procedural generation, from Minecraft to Dwarf Fortress. Mesh generation is just one aspect of procedural generation which encompasses topics such as texture generation, object placement, and even story generation.
By the end of this course, you'll be able to generate unique and impressive landscapes from code ready to use in your games. Source code is included to help you on your way.
I designed this course to be easily understood by intermediate level coders and users of Unity with no previous experience of mesh generation.
I present examples of increasing difficulty designed to help you to understand exactly how mesh generation is done, and guide you through the theory behind it so that you can be confident in creating your own meshes.
For extra support, you can ask questions in the Q&A section, and I've provided the completed code examples for download in each Section. You'll receive a certificate of completion once you finish the course.Who this course is for:
  • Intermediate level Unity developers who want to learn procedural mesh generation.
  • This course is not for people new to Unity or C#.

This course is fine. However it tries to squeeze at least 10 hours of content into 3. Does not explain contents deep enough for me. It is quite hard to keep up with the pace of the instructor.

It was a great match for me. I have just two suggestions. The code display was too small. It needs to be very large on my screen, so that even when it only has have the window, I can still read it. Also, sometimes to cut away from the script to the Unity editor too quickly, not given me time to catch up with your script typing.

So far, the instructor's pace is perfect, and the visual aides were a very pleasant surprise, as I find this sort of thing really helps me retain these sorts of concepts. ?

This is a nicely mapped out course. I actually liked the fast pace which got me up and running quickly and with enough knowledge to continue applying these techniques to my own work. I would definitely recommend this course.

Great course that moves swiftly through the basics to make sure everyone has the knowledge required for later material. By the end of the course, I generally feel like I understand how to create procedurally generated meshes.

Well, I'm kind of a beginner. I think the material is very compact and concise, but I could use a little more explanation of the math involved. But I guess this course assumes that you already know how the math applies.

Not sure about this course.. Feels like I am just copy/pasting code..It's like a GPS in a car. "Turn left, turn right.." as she is typing out the code. With me having no idea why she is telling me to go left or right, or where we are really going..I guess this course is more for people who know how to do procedural mesh rendering, but want to learn an alternative way to write the code.

Start is nice and easy

Jenny develops several scripts for generating simple geometric objects as well as landscapes. I found the scripts to be a great starting-off point for my own projects. The course could be improved by spending more time explaining and less writing the scripts, but that shouldn't deter anyone who's interested in PCG to take a look.

The Instructor is very knowledgeable however, it is difficult to see her code because she does not enlarge the screen and she goes at a fairly fast paste. If you are familiar with unity you should have no problem.

This is a great course and provides a lot of great information. I did struggle to keep up at some points especially during 1 or 2 of the coding sections involving the complex mathematical equations, but this course really makes me want to learn even more!

I enjoyed this course. It was straight to the point. A couple of gripes were when editing the code jumping up and down from functions to the top to add variables and then jumping down again as I sometimes missed what had just happened and had to re watch. Not a big deal. My other gripe though probably only an issue for myself as I don't have the best eyesight was the small font used when coding. I found this difficult to read on some videos and had to rely on the downloaded code. But apart from that, good course and nice learning curve.
