When I use the switch object function, if I change the furniture by setting the trigger and clicking it, the shadow of the furniture before the change remains messy. Is it an error? If it’s not an error, please let me know how to solve it… I want to make sure that shadows exist, but not the shadows of the previous furniture.
Hi,
This is not en error. All objects used in extension are casting shadows and they are baked into the lightmap. To avoid this problem in the Objects tab turn on isolate shadows for all objects used in the extension. Here you can watch a tutorial about this extension: https://www.youtube.com/watch?v=EHPeuqKQWhs&t=7s
