Perspective View Material Glitch - Revit LT 2023

[strandedgroup]

Hi All, 

Long-time Revit user here and I'm stumped on this issue. Revit 2023, in my opinion, has been the most important and productive update since 2018, however, in true Autodesk fashion it comes with another problem to fix. 

For me, this is graphical in nature and I wanted to know if other people are experiencing the same issue. 

In short, essentially in all perspectives or 3D views (full colour, textures, shadows), my topography can lose its texture and go completely black. This can affect all sub-regions within the topography but does not affect anything else other than topography. For instance, all other flat objects like floors, roofs, and families, don't have this issue.

Now, the good thing is it can easily, but annoyingly be fixed by simply adjusting the section box or crop region. Literally adjusting any of those elements "refreshes" the rendering and it's fine. That being said, if I leave the page and come back, the same or a similar issue can appear. This requires me to print my perspective PDFs one by one as I fix each page, which is a huge time waste. 

Some thoughts on this. 

- It has nothing to do with phasing as it affects all topography regardless of phase. 

- It has nothing to do with a material type as it affects any material I apply to it. 

- I have played with rendering settings and it is not affected by shadows, lighting quality, or detail level. 

I initially thought it was my system and video card, however, I've gone through 4 driver updates and the recent Revit LT 2023.0.2 update and it has resolved nothing. I have also installed Revit 2023 on my AMD laptop and it suffers the same issue, which leads me to believe it is a more widespread problem that's likely affecting more people. 

Given the installation on my laptop, I'm not sure if removing and reinstalling is going to fix things here. 

Is anyone else experiencing this? A snippet of my problem is attached below. 

Thanks,

I should also add that this affects every Revit project I have. It's not unique to one given file.

Thanks for the idea, I looked into the link and played with a few more options to see the reaction and nothing improved. I still get the same issue. It's worth noting that this is solely a Revit LT 2023 issue, 2022 works fine.

You know, I have issues with 2023 as well. Sounds like mine are related to yours. I've been meaning to Open a Support Case on it but haven't got around to it.  Why don't you Open a Support Case through your Account Portal and let us know what they say?
