Building my first AE plugin using the example checkout - layer unvisible
Hi,
I am trying to learn how to build after effects CS6 plugin using Microsoft visual studio.
I managed to make a test plug using the "checkout" example from the SDK but whenever i apply it to a layer (solid or anything)
My layer which i applied it makes the solid disappear (attached JPG)
This is the code i used to compile.
#include "Checkout.h"
