Description
Important for TSL functions that use
.once( namespace )
to ensure that the namespace will run twice,once when the node is build in the specific namespace and once when the node is built in the others namespace.
This is useful for nodes like
positionWorld
that need to be re-updated if used inmaterial.positionNode
and outside of it in the same material.It was initially done here for
positionNode
, but now the API can be used for other inputs like the one planned for the normals solution.
