Hi Dave - I would reset all of your visual settings back then to the default value and then start to increase the size of the export to the desired value. You may not have changed the computer settings but the project could’ve also become more complex. As entourage and complexity increases the demand for memory increases on your graphic card.
Also go to your Enscape feedback button and submit a feedback report. This will allow the support team to see your computer settings and possibly have a closer look and identify what’s causing the crash.
I’ve opened up other building models and rendered scenes with no problems.
Then i go back to the file im having trouble with, which has become one of those old revised, revised, and revised again interior models that i’ve imported many custom lights, furniture, etc… and the revit file is quite messy perhaps. Something in the past few weeks has made the revit file in question quite complex and Enscape is having trouble rendering it.
Im making a clean new revit file, and then going to copy paste only the building elements i need into the fresh file from the old and see if i can leave the problems behind in the old file.
I’m going to try this strategy before i mess with settings since everything has worked great up until a few weeks ago with this project.
Thanks, I’ll update the post if this fixes the problem.
Hey Dave – do you have any 2DDWG files cluttering the project? I found that these can create memory issues but they never get rendered in Enscape. You might also try to purge your Revit file and see if that gets rid of a problem.
No, i have removed any linked CAD files and purged and compressed the file nicely.
Enscape did just email me with a response to my issue. Apparently it is within Enscape and they are working on a fix. In the meantime the work around is to use scope boxes to reduce the items factored into the render, and then if that doesnt work to reduce from Ultra to High resolution. So far using the scope box to narrow down the model to only what i need has worked this morning. I also turned off the outdoor landscaping assets since in dont need them for the interior render scene.
Perhaps there will be an update to Enscape soon to fix the bug.
Thanks for your responses, as they are also very reasonable items to address for any modeling regardless of any bugs in Enscape.
I think its lack of memory. I have this exactly issue. Not sure if its an enscape issue or just my computer.
I have 16 gb RAM on my personal and 64 gb RAM on work computers. And I can render just fine on Ultra with the 64 gb. Meanwhile on 16 gb, I can only render on medium.
Your computer has memory but your graphic card also has memory. The 64gb of RAM that you reference is your computer memory. NVidia GTX 4000 graphic card has 2gb of memory.
Enscape is very GPU dependent and requires a discreet graphic card with at minimum 2gb of RAM. I would suggest a graphic card with a minimum of 8gb of RAM and preferably the Nvidia RTX 2070 / 2080 as a minimum.
Here’s a benchmark comparing your graphic card to the Nvidia 2080 RTX.
The NVidia GTX 4000 has only 2gb of RAM which is the functional minimum. I suspect this is the bottleneck. Your graphic card is running out of memory resulting in the crash.
Can you clarify the GPU? “GTX 4000” isn’t really a thing. A “Quadro 4000” would be really old, and doesn’t fit with the 9880H (which is a mobile chip, assuming you are on a laptop?)
I’m guessing it’s a P4000, or RTX4000, which should have 8GB of VRAM and be sufficient for most projects. You can check your GPU usage in Task Manager and see if you are bumping the limit.
This may very well be resolved with the latest hotfix coming out later today, but as Phil mentioned above too, 2GB of VRAM is really the bare minimum we recommend although when it comes to larger or more detailed projects those 2GB may (and pretty likely will) not be sufficient in the long run.
Then in this case you should be good to go with the update later!
