drmdzh Posted April 27, 2015 Share Posted April 27, 2015 I have been working with a student building a 3D model of a black box theater. Her vw file is the same as everyone else's in class, but we're having a stranger problem when we switch to any view other than top/plan. When you use the flyover tool, blank spaces appear and "erase" parts of the model. All of her wall appear hollow (I have extruded objects in her file and found the same problem, she's not doing it wrong.) I have attached some jpgs showing the issue. Thanks. Quote Link to comment
barkest Posted April 27, 2015 Share Posted April 27, 2015 Could you post the file? Quote Link to comment
barkest Posted April 27, 2015 Share Posted April 27, 2015 (edited) I believe the trace layer is the issue. Switch off unified view and all is ok. The trace is in the screen plane - change it to layer Edited April 27, 2015 by barkest Quote Link to comment
drmdzh Posted April 27, 2015 Author Share Posted April 27, 2015 Thanks for the suggestion, I don't think that's it. I switched off unified view and the issue persists. Also changed the trace layer to layer plane, and even deleted the trace layer entirely, but it didn't change anything. Quote Link to comment
Kevin McAllister Posted April 28, 2015 Share Posted April 28, 2015 David, Something is corrupted in your file or its potentially a bug. I've seen this graphics issue before and it will usually be solved by copying and pasting into a clean file. In your case it can't. I would submit it to tech support or perhaps Jim will see this thread and take a look. I've seen this happen quite often with the Educational Version for some reason. Kevin 1 Quote Link to comment
drmdzh Posted April 28, 2015 Author Share Posted April 28, 2015 OK, thanks so much for taking a look. Good to know it's a bug and not something we should keep trying to find a fix for! It was driving me nuts thinking I had changed some preference somewhere. Quote Link to comment
AlanW Posted April 28, 2015 Share Posted April 28, 2015 All looks good on a powerful computer but I am sure if you try to rotate on a smaller computer in the render mode (Fast Render mode) that the file is set to when I opened it there will be some lag till your graphics card catches up. Does the blank spots occur in openGl when rotating?? This will tell you. Quote Link to comment
Kevin McAllister Posted April 28, 2015 Share Posted April 28, 2015 Its not a computer power thing, though it may be related to the MacBook Pro graphics drivers. I work with much more complex models all the time and I'm seeing the same issue when I open the file. KM Quote Link to comment
barkest Posted April 28, 2015 Share Posted April 28, 2015 (edited) Had another look and it seems to be a lighting issue. See my earlier post on lighting and openGL as they may well be related. screenshots attached both in openGL Edited April 28, 2015 by barkest Quote Link to comment
AlanW Posted April 28, 2015 Share Posted April 28, 2015 (edited) Hi, I think there is something in your file causing problems so i copied parts over to a new drawing and got the following results without changing anything. I think I copied all the parts over except the bits outside the room. Couldn't see what was causing the problem but after i copied the items over the colour started to show immediately and i have not altered any settings only started an new drawing and copied over bit by bit. See if this is ok?? Edited April 28, 2015 by Alan Woodwell Quote Link to comment
Kevin McAllister Posted April 28, 2015 Share Posted April 28, 2015 Had another look and it seems to be a lighting issue. See my earlier post on lighting and openGL as they may well be related. screenshots attached both in openGL Barkest has it I think. Its related to that one lighting fixture which seems to be corrupted. If you delete it everything behaves normally. KM Quote Link to comment

barkest Posted April 28, 2015 Share Posted April 28, 2015 I am not sure it is corrupted I believe it is an issue with OpenGL and the light as it works fine in all other renders. Something has changed wrt OpenGL rendering and lights in 2015 (from at least sp 2 and maybe sp 1). Quote Link to comment
AlanW Posted April 28, 2015 Share Posted April 28, 2015 Yes, I have been told that certain lights wont render in openGL mode so you need to render in other. These include line lights etc. Quote Link to comment

Something has changed wrt OpenGL rendering and lights in 2015 (from at least sp 2 and maybe sp 1). That may be true. But if you take a look at the original file exhibiting the problem its actually rendered in Fast Renderworks..... KM Quote Link to comment
