When I click on preview in the material test generator , no image appears. Maybe my windows too old or something with the older graphic card? Does anyone know a fix. About half year ago it showed the preview just fine, and suddenly it disappeared. Even after the 2.0.01 update, no difference…
it’s a i7-6700 CPU @ 3.40 GHz / Geforce GTX 1080
Just a stab in the dark, try zooming out, you may be zoomed in so far all you are seeing is the space between the squares.
If the PC has an i7 processor, it is likely Win10 and not too old.
Maybe zoomed out so far that all you see is one dot.
Betting a setting got changed, you just have to find it.
