I have an existing landscape that I've been working on, meaning I've been painting materials and reshaping it. I've had no problems with this. Last night I added a component to the landscape to create an island off of the main landscape. To do this I had to add two components that were attached to the main map, then delete the first added component. This worked without too many problems but when I tried to paint the materials on the new component, everything turned black. I've tried rebuilding the lighting but that didn't do anything. The editor becomes very laggy and unresponsive when I attempt to paint. Changing the heightmap with the paint, flatten, and erosion tools seem to work. Not sure what to do. Any help or advice would be appreciated.
