Render not exporting, hangs on Estimating...

It's been a year and half since this post and this still seems to be an ongoing problem. I'm new to 3D modeling and I will be honest I learned a lot from Stager and the awesome community that have put up learning videos. I'm currently on the trial version of the Adobe Stubstance 3D Stager and I don't think I will be subscribing after the trial ends. I honestly like Stager a lot, I love what I have created. But sadly it seems that this software has been neglected, shoved in a dark cold closet.

I'm having the same issue, my macbook is old though and I assumed it was a GPU incompatibility issue but my CPU is able to export the images (although slowly). At first it seemed as though only the last camera would hang on estimating but after more tests it seems to be random.

I have reset P-Ram, fixed disk permissions, cleared cashes, ended all non essential processes, and even externally cooled my machine to see if any of these helped. Nothing seems to change the outcome. It's like rolling a dice, regardless of project complexity or size it randomly happens. 

I had accepted that perhaps my machine was just too old and would give up, but the fact that you are experiencing this on an M1 machine is concerning. 

I have the same problem. I have Nvidia GPU and as soon as I select render, it just hangs on estimating. Nothing happens. Adobe Dimensions would load it much faster. I even disabled render with GPU and still stays the same. Even if I select DRAFT settings... Pls fix this I cant render anything.

I am having this exact issue too. It takes almost an hour for a single medium resolution images and once it gets down to 1 minute left it switches to estimating and just hang up there and never finishes. I'm just curious what type of machine you are on? I have an iMac with an M1 chip so I'm thinking maybe it has something to do with that. I hope someone from adobe will chime in on this glitch.
