Weird Colors after building lighting

I have a rainforest, and when I build the lighting my trees turn into a weird green color…

And also happens with some of the leaves on the trees

To prevent any problems on building lights you need to make a better UV map without overlaping faces and wrapped in the correct mode. You need to make it in your 3D software package. Then in UE4 in the settings set the lights to the new UV.

I thing the UV maps don’t have overlapping faces because this was made with the kite demo Content, so I think it is well made

I think this is because the bouncing lights, for some reason the lights are bouncing in the leaves, making the other trees a green color, but it’s doing it incorrectly
