Problem with dual lobe in Blender 2.79
Issue #143
resolved
I have recently revisited Blender 2.79, because Blender 2.83 seems to have severe performance problems. Here is Victoria 8 rendered in Blender 2.79 (left), and after I remove the Dual lobe node group (right). In Blender 2.83 everything is fine.

Thomas I don’t know if I may help with this, but could you explain please what performance problems are there and possibly some steps to reproduce the issue ?

Fixed now. In B2.83 a multiply-add node is used to calculate the ior. Since such a node does not exist in B2.79, a multiply and an add node are used instead, and I forgot to add the ior.
