// _FORWARD_PLUS keyword deprecated in 6.1
// We will emit a warning and define deprecated macros for backwards compatibility.
// This file will be removed in a future release.
// To upgrade custom shaders, replace all instances of the deprecated macros (left) with the new macros (right):
// _FORWARD_PLUS _CLUSTER_LIGHT_LOOP
// USE_FORWARD_PLUS USE_CLUSTER_LIGHT_LOOP
// FORWARD_PLUS_SUBTRACTIVE_LIGHT_CHECK CLUSTER_LIGHT_LOOP_SUBTRACTIVE_LIGHT_CHECK
#if defined(_FORWARD_PLUS_KEYWORD_DECLARED) || defined(_FORWARD_PLUS)
#warning _FORWARD_PLUS shader keyword has been deprecated. Please update your shaders to use _CLUSTER_LIGHT_LOOP shader keyword instead, otherwise shader compilation times may be negatively affected.
