Tutorials - gradientspace

I’ve just released Cotangent2, a mesh-editing app I’ve been developing since I left Epic Games in 2024.

Today I am releasing a beta of Gradientspace Graph, my C#-based NodeGraph programming environment.

The Gradientspace UEToolbox plugin is now both Free as in beer (on FAB), and Free is as in freedom (open-source, on Github).

If you spend any serious time trying to assemble scenes in Unreal Engine, you probably have run run across strange transform behaviors that occur when you have any kind of hierarchy of Components in an Actor.

Gradientspace 1.0 came to a somewhat abrupt end in December 2018, when Tim Sweeney offered me a bag of money to open-source all of my code and join Epic Games.

Geometry Script(ing) is a Blueprint/Python (UFunction) library first released in Unreal Engine 5.0 that allows users to query and manipulate triangle meshes (and a few other geometric data types).

During the last few major versions of UE4, a stack of libraries was built up in the service of the new and expanding Modeling Editor Mode.

In Unreal Engine 5.0, Modeling Mode includes a large set of Tools, built using the Interactive Tools Framework, which allow users to create and edit meshes in the Level Viewport.

In this article, I am going to cover a lot of ground.

no static meshes were cooked in the making of this level.

In my last tutorial, I showed you how to use the new experimental GeometryProcessing plugin in UE4.26 to do useful meshy things like mesh generation, remeshing, simplification, and Mesh Booleans (zomg!).

This is the first of several tutorials that will (hopefully) teach you how to do advanced Mesh/Geometry Processing with Unreal Engine.

The code for this tutorial has been updated for UE 4.26 - see the update notes below!

Winding number of different regions inside and outside a mesh with self-intersecting and overlapping components.

Recently geometry3Sharp user samyuchao asked a question about a topic I've been meaning to write about for nearly a year.

This is the first of a series of posts about how to directly generate GCode for your 3D printer.

Most of the tutorials I've written so far have focused on geometry3Sharp, my geometry-processing library.

[Update July 6, 2018] My new tool Cotangent has several Tools that use the operations I describe below, if you want to try them without writing C# code.

Let's get this out of the way up front: If you are mostly interested in the 3D geometry things I do at gradientspace, this post is Not For You.

If you are using the g3Sharp library, there is a good chance it's because you need to do some things with triangle meshes.
