Hi,
I have a problem with my shadows in Rendermode in Viewport. This Problem exists only in WIP Versions starts in January until now (regular 5.1 is ok). If I start a new document and set Viewport to “Render” everything ist ok. (pic1).
Than I make a measurement and the shadows of the objects “goes inside”. (other pictures).
I can only fix the problem by restart Rhino completely.
I use a mbp 2009 with nvidia 9400m an El Capitan.
