Anastasia Linovich Posted June 9, 2021 Share Posted June 9, 2021 I apparently have some software failures for a long time for now. The main sign is that the rendering quality of the open gl always deteriorates. It goes from high level of quality to the low one with no reason. Mainly the textures just disappear. When I am trying to fix it manually in Open GL rendering options, sometimes it helps but usually not. Also the vectorworks closes accidentally when I am trying to save my work. I have the updated version of vectorworks 2021 and my laptop is not overloaded, so it is not related to that. I also have other problems especially in the way rendering function which neither my tutors nor me cannot fix. So I need to realise why these glitches appear and how to manage it?

grant_PD Posted June 9, 2021 Share Posted June 9, 2021 Can you post your hardware specs? My first thought is that your computer is running out of memory in the video card. But it is hard to say without knowing what you are working on. Quote Link to comment
Jesse Cogswell Posted June 9, 2021 Share Posted June 9, 2021 One of the biggest traps of doing rendering in viewports on a sheet layer is the sheet layer's DPI setting. For whatever reason, Vectorworks defaults all sheet layers to a DPI of 72, which makes Renderworks and OpenGL viewports look really low res and messy no matter what settings you set the viewport to. To fix this, open up the Organization dialog, go to Sheet Layers, and select any sheet layers with rendered views on them. Click Edit and change the Raster Rendering DPI to something like 300. I typically make all of my sheet layers have a DPI of at least 300, even architectural drawings (makes PDFs MUCH crisper looking), and final "beauty" rendering sheet layers I set to a DPI of 600. Keep in mind that exporting to PDF, a full page 600 DPI rendering will make the file size pretty huge (as is typical for PDFs from VW), and having Save viewport cache turned on in the Document Settings will result in your VW files being huge (back ups, too), but will save time not having to re-render every time you open the drawing. 2 Quote Link to comment

Yes, perhaps the 72dpi is too low for the default - and yes there could(should) be a quicker more visible way of monotring/ adjusting it But otherwishe - DPI adjustment on a SL is actually one of the great advantages of Rendering in Vectorworks. You can layout the SLVP(s) as needed in the finals and drop the DPI to somthing very small (20 DP) for Lookdev. Then when the views, lights, materials, content etc. looks right you can start turning it up. This is a great timesaver - rather than test-rendering at full output resolution. You wil save hours.

twk Posted June 9, 2021 Share Posted June 9, 2021 Another thing that comes to mind is the position of the model in the design layer. We've noticed if you draw too far away from the origin, or your model is too far away, the openGL render craps out. Quote Link to comment
Boh Posted June 10, 2021 Share Posted June 10, 2021 I had pretty much the same problem a week or two ago and it was my model had geometry to far from the drawing origin. I.e. what @twksaid. Quote Link to comment
