Render Lighting Effects not working?
I have been trying to add a lighting effect to an image, but whenever I go to filters>render>lightingeffects it pulls up a black screen. I've found that turning up the ambience lets me at least see the image, but beyond that nothing works. All the other sliders seem to have zero effect on the image. I've updated by graphics card, made sure I was working in 8 bit channel and RGB, I've even ticked the legacy compositing box. I'm using windows. I've been searching all night for answers and cannot find any. Is there anything that I'm missing? Is anyone else experiencing this issue? Please help!
