Hello!

I’m Jon and I’ve a problem with the lighting of the trees. I don’t know what’s wrong. The material for the branches is set to Two Sided, Masked and Subsurface. I added SimpleGrassWind and applied. But the result is that:

 ![203410-screenshot.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/8/9/2/892872271a2ea253ca57c8d86add0f6985954662.jpeg)

There are ugly black/dark locations on the branches. And I don’t know, how to fix them.

Thank you for help.

- Jon

Hi, Jon!

It’s seems like your tree is static object for lighting. To objects that should moves, you need to change mobility to “Moveble”. Also you need to build your lighting, so go to the Build tab, set lighting quality to “production” and build it.

I hope this helps, good luck
