Here’s the setup, my building is partly covered by mountains through a landscape object (last screen, from outside). I sculpted the invisibility mask inside the building to hide the terrain.
But when I built the lighting, the shape of the hidden terrain seems to have blocked the light and it’s shown as a dark area on the walls and floor (first screen, from inside).
I included a screen (second) from the ‘lighting only’ view mode where the terrain is still visible.
I did a bit of searching on this issue, but there wasn’t a lot documented. So I hope someone could tell me if I’m doing something wrong or this is just a bug.
I have a couple of suggestions for you to try to hide your landscape shadows. The first suggestion deals with using level streaming and triggers to effectively hide your entire landscape when entering this building. This will take all the information tied to the level with the landscape in it, including shadows and other meshes.
The second suggestion would be to force hide and show your landscape with a trigger when entering an enclosed area where you will not need to render/see the landscape. Since you are baking your lighting however, you will need to turn off ‘Cast Static Shadow,’ on your landscape in order for the shadows to remain hidden when toggling the visibility.
The first option will probably be your best choice because you can effectively use the same streaming command to hide and show your landscape wherever you are entering a room or building. This will allow you to bake your lighting with the ‘Cast Static Shadow’ option for you landscape.
Level Streaming/World Composition Documentation
There is also some great examples of level streaming within the ‘Content Examples’ project.
Let me know if you found these ways effective or if you need further assistance.
Hi, thanks for your response.
Due to a deadline, I had to come up with a solution which happened to be a bit more barbaric. I just sculpted the landscape around the building with flatten etc. And I hid the ugly seems with construction blocks.
I will bookmark this response for future reference, it looks like a better solution.
