At first I kind of suspect the flickering may causes by shadow map, therefore I changed from Raytrace shadow to Depth Map shadow, by doing so the rendering time had been shortern up and faster but yet it still flicker when the camera moves around or either the character is moving. I'm not sure what is the problem that causing the flickering, it seems nice and pretty when it's a still image, but it's totally out of question when the is a animation. The following is the setting I'm having now.
Light type: spot light
Shadow type: Depth Map Shadow
Shadow bias: 0.08
Shadow Intensity: 1
Shadow Quality: 10
Shadow Softnes: 5
Auto-generate Shadow Map: checked (on)
Shadow Map scequence: created
Resolution: 2048 x 2048
Pixal sample: 3 x 3
Render Engine: Micropolygon Rendering
sampling Sample Pixal: 8 x 8
Is there any way to solve the problem, should I use PBR rendreing???? It would be an expensive way for the machine that I'm on.
