You will no doubt be importing the foliage into your own scene and will set the lighting as needed there rather than inheriting the lighting scheme from any of my demo scenes. In many of my scenes the skylight is set to Stationary but I find this leads to shadows/shading that are too dark. I prefer the look with the skylight set to Moveable/Dynamic but other factors may determine this for you. 4.18 (no ray tracing) in an attempt to show the "worst case scenario".Īlso note that you can choose whether to set the skylight to 'Stationary" or "Moveable" and this has a dramatic effect on the appearance of the foliage. It's a bit long-winded but I think it will make many things clear if you have questions.īe aware that the renderings below are all from ver. There have been numerous posts since the start of RTX regarding issues with Foliage Instances and it seems yet to be fully resolved.įor an in-depth explanation of the problems and solutions regarding Ray Tracing and Foliage Instanced Static Meshes, please refer to my more recent post here. This will result in the use of Cascading Shadow Maps. If you plan on using the foliage assets with a Ray Tracing version of the Unreal Engine, at this time I recommend disabling "Cast Ray Traced Shadows" on your light source if you are planning to use the trees with Foliage Instancing. *A Note About Foliage Instancing with Ray Tracing:
Each Demo Level alsoĬontains the UE4 Mannequin for scale reference. Note that the staging environments for theĭemo Levels are for demonstration purposes only and contain a few additionalĪssets from the UE4 Starter Content and Content Examples. There are Demo levels for each tree and a “Library” LevelĬontaining just the core content. Ideal for architectural visualization but also most game environments. Than 20K polys with most below 15K and several below 10K. “Cinematic” models and lower poly gaming/VR assets. These trees are meant to fill the gap between high poly Large groupings without obvious repetition. Tree species includes 3 procedural variations allowing you to create forests or Representing 5 common species of trees and 5 unique indoor plant pots.
