Bug Build time taking almost a day - URP

The only thing I could really improve there was to disable hard shadows, which I did. This shader doesn't use shadows (I believe?) and therefore shouldn't be affected by it.

But - this was a 100% warm build - what was the 4.5 (est) hours spent doing? 0 shaders should have been compiled, and Unity definitely shouldn't have taken half a working day to go "Yup, no work to be done!" - the only change between those 2 builds was the changing of a single piece of whitespace in a random script file.

 

I don't fancy your cloud build bill.

 

Any updates on this? We're using 2021.3.15, and we're still seeing 14h cold builds. It's making it damn near impossible to troubleshoot errors that only show up in build.

 

What a terrible system . Using just the default shaders, absolutely ZERO custom shaders and the build time is still INCREDIBLY long (like 15x times) compared to built in.


No one in their right minds should use anything else but the built in. Its stable, fast , bug free absolutely superior to this slug thing called urp.
Just get back to supporting built in and burry this thing 5 feet deep in the ground.

 

So, from October till now, nothing yet?

 

Fair enough, why I'm having 33 hours of cold builds then?

Hi, Unity please stop your defensive attitude. I had no trouble building with SRP. In SRP it only took 30-40 minutes. But when we change to URP. It takes hours. We didn't complete the build because it took too long. We don't have time to wait. We changed it again to SRP.

Please stop this defensive attitude. Acknowledge URP is broken and fix bugs. Stop blaming user error. I've been using Unity for 6 years. Do you think I'm a noob who can't tell the difference between a user error and a bug?

 

With the upgrade to Unity 2022 LTS (URP) I got a 3 hour cold build. I think switching unity versions even with small increments always result in a full cold build, not sure. The warm builds after this were only 1 minute. Everyone's project is different so this might not be the same experience for everyone, for me at least it has improved during the lifetime of this thread.

It used to be unworkable, but now I can plan around the cold builds. And the warm builds are good.

 

Hello, Arnold_2013 Could you please tell, what was the cold build time before upgrade to 2022 LTS.

On my project with 2021 LTS and URP, cold build time is about 16 hours. Now I'm thinking how rapidly should I upgrade to 2022 LTS.

 

With this update I came from 2022.2.1f1, so I can't really say anything about the potential benefit from 2021 LTS to 2022 LTS. I would imagine most of the fixes will have been backported to 2021 LTS. So upgrading would not help.

The warm builds on 2022.2.1f1 were also not too bad (5-10 minutes), but older versions would give me warm builds of ~1 hour which was my main problem back then (sorry I can't find a version number or date for when this was). So it seems to me progress has been made on the long build times.
