v19 Sketch Render bug ....or....WHAT????

Model looks fine in OpenGL preview, cannot see a result when I render as a whole image, just a blank render using any sketch setting engine (no error messages).

When I pull it apart (in my attempt to deduce) the issue, I can render the left, center and right portion with some overlap, but not the unit as a whole. Any suggestions?

I've had success in v19 on other smaller massings using sketch, and this one isn't too detailed by my typical standards, but somethings up......

Also getting a lot of blank renders
Mostly in sketch option. Very annoying

Update: the hidden line render cycle gets through step 14/15 then blanks out when the whole unit is rendering and fails. When the partial building renders, it goes all the way thru step 22 and produces the intended result. Also, I can render with the internal engine but not the Maxon engine. Still no suggestions? - L

Now it seems to be related to the "show vectorial sun shadows" button. There is a conflict with this and transparency. I can render the whole unit with sun shadows turned off (both with and without transparancy), but it will not render as a whole with shadows and transparency ON. I can render portions of it with BOTH on, however.

I even inserted the model into a new base template. The 1st attempt rendering produced one shade and transparent image (as expected), but moving the camera broke the spell and I'm back at the corruption issue.

I will report this to Graphisoft for investigation.

But in the meantime, I noticed you have a 12-core Mac Pro.
I do not mean to hijack this thread but I would be very interested to hear about your experiences with this machine in ARCHICAD 19.

Thanks for reporting this bug. It's a big deal for my workflow.

RE: The 12-Core. I've only been running v19 on it for about a week and a half so I haven't been able to flex all the muscle I expect it to have. Yes, the elevations with texture and shadows are faster, but by how much, I can't tell. Since I haven't been able to (repeatedly) achieve a successful sketch render with all the settings on, I can't fairly reply to this either. I have not tested the Maxon Engine, as Atlantis is still my familiar workflow. If you have a benchmark file or evaluation tool to compare times and speeds with, please contact me and I would be happy to post review.

I just loaded a LARGE file that I created in v17 and did a render test on both. Ironically, the shadows and transparency worked this time on this file using v19. Comparing the speeds to generate the exact same sketch render, I was surprised to see that the v17 render was 2 seconds faster.

Here are a few more observations regarding idiosyncrasies or bugs since I have your attention.

1 - When I have multiple sessions (projects) open in v19 on my Mac, when I close one of them, the dock icon still shows it being open with it's file name still activated with that small white banner across it. I have to quit the additional session to make remove the file name.

2 - If I close a project file while there are still "tabbed" render images left open in the viewport, the project file itself closes and saves, but I get a save dialogue asking me to save the "xxxxx.pln" file instead of the actual tabbed image file, i.e., "Picture #3". Its confusing and makes me second guess whether I successfully saved the .pln file and all the work I did in it. I guess I'm surprised that the actual CAD file will close before the images generated in a session.

I can't get attachments to load properly. This is the speed comp image.

by the way.........incase anyone hasn't told you....VERY nice rendering technique, view angle selection and perspective in general.
I use a similar "sketchy" technique as well.

would love to pick your brain a bit over the phone on certain, techniques.

I was just wondering if there was any news on this topic. I am also getting blank renders. One will work just fine, the next one is blank. I have found that if I adjust the view just slightly, sometimes that will work. Strange. Doesn't happen every time either. Just seems to be random. I don't think its my computer either. Its new with 6 cores and 16gigs of ram so I hope its not my computer.
Thanks for any ideas.
