Can't seem to find the answer to this with a search.
In Max 2017 I'm doing some concrete fixed cladding but the material is showing up black in the viewport. If I apply a generic vray material it's ok but the in-built material won't show up, though just tried now and switching the viewport to high quality then back to standard does show up a colour. What it doesn't do is change the colour if I change the material in the parameters.
Any ideas?
