| void gpu_node_graph_optimize | ( | GPUNodeGraph * | graph | ) |
Optimize node graph for optimized material shader path. Once the base material has been generated, we can modify the shader node graph to create one which will produce an optimally performing shader. This currently involves baking uniform data into constant data to enable aggressive constant folding by the compiler in order to reduce complexity and shader core memory pressure.
NOTE: Graph optimizations will produce a shader which needs to be re-compiled more frequently, however, the default material pass will always exist to fall back on.
