As title. I appreciate that 3d models require directional lighting, but I wonder if there is a way to make it more uniform, and bright, for making spritesheets from all directions.
So yes when you are selecting the layer you can edit the directional light :
It depends of your camera orientation but if you want the light to come from the top/front, you can set y rotation to 0 and only play with x rotation. And for the brightness you can increase the intensity.
