To conclude the course we build out a couple more procedural props and learn how to create textures with Houdini using its own Compositing Operators. We look at how to utilize Unity's Detail object system with Houdini Engine and how to use Unreal's grass system. Once our Terrains are ready to go we will walk through the process of efficiently creating and Scattering foliage using the Houdini Engine. I dont seem to be able to get Houdini Engine plugin to work in Unreal 5.1, I had it working just fine in 5. We will learn how to hook up terrain layers so we can texture our terrains in Unity and in Unreal. With the Track in place we will walk through the process of creating Procedural Terrains with Houdini and the Houdini Engine. This will begin to open up the power of using Proceduralism in your game productions. ![]() These attributes give you additionnal control over your assets, by allowing you to manipulate them with the standard gizmos in Unreal. Through that section of the Course we will see how we can detect the direction of a turn in the Track so we can place either a Track Bumper or a Track Guard Rail. With Houdini Engine for Unreal, both Houdini curves and Unreal splines will generate curve SOPs, whose points will contain additional rot and scale point attributes. With the Track tools we will learn how to effectively build a set of HDAs that will generate a Track complete with UV's, the Track bumpers, and the Track Guard Rails. Once armed with that new knowledge we move onto the next level and start building out our Track tools. ![]() The course starts out by giving individuals new to Houdini, a quick start guide to using Houdini by teaching the basics of navigation, UI, modeling and creating Houdini Digital Assets. You will gain the confidence to begin building your own procedural race track tools for use inside of Unity 3d and Unreal Engine 4. Throughout this course we are going walk through every step of the way so it is not confusing at all. Simply put having default Parameters and Inputs here would be superb.Have you ever wanted to speed up your level creation using Procedural Techniques? Have you ever tried to use Houdini or the Houdini Engine but hit road blocks that prevented you from being productive with the two applications? Then this course is for you! I would rather have a list of presets (or at least one preset per HoudiniAsset) for both (properties and instances) inside of HoudiniAsset that can be set up for different use cases. Anyway rather than hardcoding UE4 references to materials and meshes inside of HDA that can be quite generic and useful across multiple projects. But unlike unreal_instance attribute workflow, there is no way to set a reference to UE4 static mesh to apply by default and adding unreal_instance attribute to the packed geo does nothing. I really like creating instances with recommended Packed Primitives workflow as it makes it easy to work within Houdini as far as you can see the proxy instances instead of points comparing to unreal_instance attribute workflow. The last awesome feature would be Houdini Instanced Inputs and Houdini Parameters presets (or defaults) inside of UE4 as part of HoudiniAsset. It would be great to have references stored by Name or ID and the list being ordered by name as well or some kind of unreal_instance_sort_priority attribute. Project Titan is an in-house tech demo designed to production test Houdinis procedural workflows while creating a 3D environment that leverages the latest technologies in Unreal Engine 5. Meaning if I change something in Houdini or just change parameters and the order or quantity of Instanced Inputs changes the references are lost or incorrect. ![]() The other issues with Instanced Inputs I have are that they often lose references due to the list being unordered and references are remembered by index in UE4. Would it be possible to have more custom per-instance variation attributes? The most important ones would be “Weight” and material override but also other UProperties and Houdini attributes could be useful like Visibility to switch instances layers on/off or to create custom per-instance behaviours inside of HDA similar to Weight property like scale variation for example. Because VAT only uses textures and shaders to achieve the visuals on the GPU, it has a much lighter performance impact on. As every day HE user I thank you for that! My favourite is: - Instancers can now have a position offset per instance override variation. Learn how Vertex Animation Textures (VAT) provide an efficient and powerful solution for recreating complex and non-traditional animations and FX in real time. A lot of cool stuff coming in V2 that I've been struggling with in V1. ![]()
