on latest alpha, when making a connection between Box (DX11) and GouraudDirectionnal, the Geometry Input pin doesn't indicate it can accept the link. On the attached screenshots, I made a simple patch with b35.2, saved it and opened it with a35.5. TTY keeps yelling :
00:04:08 * : Invalid layout detected for slices:0,
As you can also see, the AxisAndGrid does not show up.
EDIT : Layer pins seem to be kinda working. Quad (Layer) is displayed.
