I try to create see wave by grid-meshsplit-vertexjoin operation. but after i connect mesh to constant, i cannot see texture.grid resolution is 2x60. texture coordinate is correct because it works on drawfix. i cannot go around the problem by switching to drawfix because there is not color input for drawfix.
please help to take a look at attached patch
