I'm new to Blender and running against a deadline!
How can I create dynamically with nodes a texture made up by a video with pixels cut out using a checkerboard pattern. When I say cut out I mean leaving pixels with transparency there and other pixels with RGB colors from the video.
Just RGB colors have to became checkerboard-cut, no the transparent background. The video is RGBA.
I cannot use too much subsurf and particles because my GPU is dead now :( , and the only combination of video texture over plane + subsurf + explode + particles that suits my needs depends on this node-generated texture that improves critically the performance.
This is my goal:
