I found this in the new DramaticRevealBG transform, the usual operands failing when played in WebGL. Thought you may want to know.
ShaderError: ERROR: 0:79: '-' : wrong operand types - no operation '-' exists that takes a left-hand operand of type 'const int' and a right operand of type 'mediump float' (or there is no acceptable conversion)
ERROR: 0:79: '*' : wrong operand types - no operation '*' exists that takes a left-hand operand of type 'mediump 2-component vector of float' and a right operand of type 'const int' (or there is no acceptable conversion)
ERROR: 0:79: '-' : wrong operand types - no operation '-' exists that takes a left-hand operand of type 'const int' and a right operand of type 'mediump 2-component vector of float' (or there is no acceptable conversion)
