  • Custom Primitive Data in UE4 Materials

    This video tutorial explains how you can use Custom Primitive Data in materials to add variety without increasing draw calls.

  • Houdini HDA Embedded Asset Files

    I posted a video tutorial that shows you how to embed assets into a Houdini Digital Asset (HDA). The example uses Open Street Map data to generate a heightfield that can be imported into Unreal Engine 4 to create a landscape.
