I am having some issues getting motion blur to apply to a specific layer, a road shown below.
As you can see below, I have motion blur enabled, and its enabled on the road layer (on the nested comp, as well as the actual graphic).
I'm not sure if this may be the reason, but the way this layer has movement, is by using the offset effect on the road texture. Perhaps AE is not recognizing this as movement, thus no motion blur? Or is there another reason this is not generating motion blur? Worse case scenario I can just use something like the fast blur effect on the layer, but im just curious as to why the default motion blur is not working.
I would apply cc force motion blur. If that doesn't work pre-compose then apply the same effect.
