bump2d in arnold

[xtvjxk123456]

bump2d node is differrent in core4 and core6

how to get core4 version bump2d in core 6?(old version arnold pipeline need it.)

[ramon.montoya]

Bump2d was made from a pass through shader that modifies the normal to a shader that outputs the normal directly to be connected onto standard_surface.

So instead of

standard -> bump2d.shader

you need to have

bump2d -> standard_surface.normal

yes,i understand,I mean how to make a shader like old core version bump2d shader,i need the shader in core 6 arnold for my pipeline
