From 6ddd280b21025cdce981f64cabae35348804b95c Mon Sep 17 00:00:00 2001 From: Wannes Malfait Date: Tue, 30 Mar 2021 10:15:23 -0500 Subject: [PATCH] Nodes: Expose multi input socket in python API It was not possible to determine if a socket was multi input previously with BPY. This patch exposes the flag as a read-only property of a node socket. This is important for addons which automatically add connections between nodes.
