Disappearing Geometry and Viewport Transparency Issues

[Dave Buckley]

Using Max 2018 HF4 and Corona - I'm having issues at the minute where at any random point of me working, the viewports 'corrupt' geometry that was there, is no longer there, it's there again if I go into Wireframe, but back to shaded and it's gone. Sometimes it's there in shaded but becomes transparent and I can see other geo through it. Graphics cards are up to date etc.

 

It's driving me insane as it's so unpredictable.

 

Anyone else having the same issues?

This demonstrates the issue perfectly - I just found the video while searching a resolution

Looks like an issue with Nitrous. Try going to Viewport Settings and Preferences and change Default Lights from "1" to "2" and see what that does.

I've noticed the same issue with latest corona build RC2, If I am looking through the camera, some of the objects with applied texture are entirely transparent. At the moment I switch to the perspective view, and it's looking ok.

@Ramy Default lights trick does not work for me.
