I’m following the Epic Games Unreal Engine training course available on Coursera, and perhaps on other learning platforms. The instructor walks through using the Landscape grass output node inside the master material, along with landscape layer sample nodes and a landscape layer blend node. We create a foliage Landscape grass type assets (two, one for grass and flowers). We then go to Landscape Mode, paint, and under layers we now have whatever textures we first set up and now two new ones for each grass collection (one is a collection of grass assets from a Quixel bridge Megascans asset and the other flowers from a different asset pack). According to the video I should be able to click these grass and flower layers (landscape mode → pain → Layers) and simply draw them on the landscape. Not working as intended. See video and screenshots.
Is this a bug? Is there something else that must be done in 5.5.1 compared to earlier versions before I can paint theses meshes? How does the material instance know about these foliage collections I set up?
