Hi @Anonymous
I see that you have made your first post! Welcome new member! ![]()
Which version of Revit are you using for rendering?
Please check if you have the latest updates for your Revit version.
To install updates, open the Autodesk desktop app and click My Updates. To use a web browser to install updates or a new version, sign in to Autodesk Account
Are you rendering locally or on the cloud?
Can you send us a screenshot of your render settings?
Looking forward to your reply update.

sorry for not mentioning version.
I am using Revit 18 student version.
if i choose custom render level option it is not working. i had to do it with medium it takes more time. to reduce time i want to keep my render level to 3.. not able to do it. by default if i go with custom it is rendering with level 1.
Hi @Anonymous
Thanks for letting us know! Can you share a file to troubleshoot further?
Are you trying to render locally or through the cloud?

Hello @Viveka_CD .
Walkthroughs can't be rendered in the Revit Cloud Renderer. That options doesn't exist.
I am also exporting a walkthrough with the "Rendering" option in Revit 2019.2.1 and have the same problem.
The answer to the problem is to not use Custom settings as said previously.
The Walkthrough export animation rendering only care for Presets; Draft, Medium, High or Best.
Either that or am I missing where i should set the render quality for export? Is it an oversight/a bug? Or is this "by design"?
My problem is that I think the Simplified renderer gives the best render result at 9-10 levels. But that preset doesn't exist!
The available presets Medium is Simpified at level 5 which is still blotchy and High is Advanced at level 10 and that is much to spotty.
With the built in Advanced renderer doesn't help to raise level for better quality either. That's because there is no post filtering of the spots as is needed by this type of renderer. I doesen't matter if I chose Best or even Custom 40 levels when I render stills.
Only the Cloud renderer filters the final result and Cloud doesn't do Walkthroughs.
I prefer my Render Settings set to Custom: Simplified, rendering by level (9 is good enough for most still renders) or by time (1 minute generally render stills satisfyingly.)
But when Exporting the walkthrough as an Animation with custom settings, they are completely disregarded and only renders one level, no matter what I set the render options to! All the light samples are blotchy and the light calculated viaries wildly. Sometimes the exterior lights entering the interior fluctuates from frame to frame. That behaviour is usually fixed by rendering more levels, but it is hard to tell as I can't tweak teh seattings with the custom options.
Other helpful tips:
Note:
I also export the animation to still images and compose them post render in another software since the AVI-option is unsatisfactory in compression options and can't handle longer animations. So that is not the render quality I'm conserned with. I mention this because many questions about render quality is answered by suggesting rendering AVI uncompressed.
Hi @Jim_Melin
Hi @jpm
I see what you are saying!
In the past, when I was doing more of 3D modelling, I've rendered parts of the walk-through (separately) and used video editing software like premier to combine the files, so the resolution won't take a hit.
Let me find out more information from rendering specialist.
Meanwhile here are some AKN resources:

That brinfgs me to another bug.
If I want to render it in parts and sets teh export to animation to start at frame 125 it saves it as 001 and writes over the previous first frame.
The workaround of course is to create a new folder... but man, you really know how to make a mess out of things at Autodesk, don't you?
Hi there @Jim_Melin
I heard back from the core rendering team and here's an update for you:)
They reproduced the issue and confirmed this as a bug!
They said that you are right that when the view rendering setting are set to Custom, the custom settings are ignored and the images are rendered with the Simplified renderer and 1 single level.
Their understanding is that this is a Revit issue, gathering those settings and transmitting them to the renderer.
Rendering the view uses the settings as expected.
The best I can do now, in terms of the next steps, I will log this with development who will further investigate the issue.
Have a great week!

Good that you could identify it.
Revit Rendering could be useful if only a few bugs like these could be ironed out.
Another few improvements would be that the export dialogue remembered last used settings, or that rendering frame stills by range used the actual frame numbers instead of starting from 1 no matter which start frame you chose.
Thanks!
Sure thing @Jim_Melin ![]()
As for the next improvement suggestion,please post it to our feedback page or Revit ideas page.
The rendering forum also would have more tips and workarounds.
