In this tutorial you will learn how to create a procedural bush plant in Houdini 18. We will start with the generation of the stems whose height depends on the height of the boxes selected as input. Then we will add the branches whose size and angle we will set in Houdini. We will create the UVs and assign the materials from Unreal Engine. After finishing HDA, in Unreal Engine we will be able to change the size of the branches, branches random seed, branches density and change the seasons. The methods used in the tutorial offer full control over the shape of the whole plant and at the same time it keeps a natural look. As texture we will use vegetation atlas. Can be reused in different projects with different types of styles and provides the ability to speed up the creation of content for games.
