I’m using a tracked camera, light + shadow catcher to paste titles onto a drone-filmed background. After a lot of tweaking, the animation, shadow length and taxt alignment is acceptable. But the shadow diffusion appears quite grainy, which makes it look strange when the clip is running. Why is that? Is there a way for me to make the diffusion smooth? It looks smooth in all the tutorials I have googled.
Yes, the raytracing quality was set to 2. I’m new to CC. What is a reasonable value to set? When I increase it to 10, my machine (a Macbook Pro 2.9 GHz with 8 GB RAM) freezes up. I suppose I’m doing something fundamentally wrong and need to go back to setttings?
Bump it up until the graininess goes away, or switch to the Classic 3D renderer if you don’t need specific ray-tracing renderer features.
Ray-tracing is a computationally-intensive process, often measured in seconds or minutes per frame instead of frames per second. Ae’s ray-tracer is exceptionally slow unless you have an appropriate NVIDIA card for hardware acceleration, in which case it’s only kind of slow.
