I’m stuck lighting my skeletal meshes as the mobile setting seems to only support one directional light. This seems very tricky since the character can be viewed at all angles, so either they are lit from one direction yet completely dark on the other side. I’ve tried a ton of other combinations and can’t seem to get anything else looking right. Any suggestions?
For mobiles make material that fakes lighting. There are few topics about it with material examples.
Mobiles do not support dynamic lighting.
Try adding a skylight for indirect lighting. Also we’re working on adding more dynamic light support for mobile, stay tuned
