Dappled light—the "komorebi" effect where sunlight filters through tree leaves—is one of the most effective ways to add realism and mood to an architectural visualization or interior render. If you are using versions ranging from , you’ve likely realized that while there isn't a single "Dappled Light" button, there are several powerful "generators" and workflows that stand out as the "better" options. 1. The Pro Choice: Corona or V-Ray Distance Maps
OSL shaders are incredibly fast and viewport-accurate. You can see the dappled light patterns directly in the High-Quality viewport before you even hit the render button.

3ds Max 2019 introduced support, which significantly improved in the 2021–2023 updates. You can find free "OSL Gobo" shaders online. The Pro Choice: Corona or V-Ray Distance Maps
It offers total control. You aren't relying on a static image; the light reacts to the actual geometry of your 3D trees. 2. The "Gobos" Method (Best for Speed) Recommended Tool Pure Realism 3D Trees + Forest
Instead of faking light with a texture, you generate a dense canopy of low-poly leaves.
Since Arnold became the default renderer in 3ds Max, it introduced a specific tool called . Gobo Filter: Attach an Arnold Gobo filter to your light.
Leverage the and the improved Viewport Shading . You can now drag and drop your dappled light texture into an Arnold Light and see the results instantly, making the "trial and error" process much faster than it was in the 2018 version.
