For the past couple years I have had problems with re-rendering a project and it displaying the previous render. I've seen this discussed a number of times and I've also sent in a few project files to VW to be diagnosed, but they can't reproduce it. I work on a PC on VW2020, and coincidentally this is also affecting my colleague on a Mac in VW2020. The only workaround I have discovered is to go into the custom renderworks settings, and change the Curved Geometry setting to anything other than what it was previously on. Then re-render and it works fine. But I have to make this change in the settings every single time. Through trial and error I've found that ONLY the Curved Geometry setting will change it. Am I the only one having this problem?
