Shader compile using just 4 materials one a very simple model (4000 polys) takes longer to compile in UE5 than it does to bake a whole scene in Unity.
Its so slow (at the moment compiling over 10 000 shaders) that it completely destroys any workflow.
I can’t afford the time to wait, so back to Unity unless anyone has a solution.

It is a disaster. RTX 3070 8GB OC, Ryzen 5 3600, 64 GB RAM, SSD 1TB / 970 EVO NVME M2 … and just for reopening a simple project with landscape and all the “medium quality” assets downloaded from Quixel, takes me like 5 min to open the project and then 10-15 min compiling 10K+ shaders. I have just grass, water, a house and some lightning set up in the project. can’t imagine how it ;looks like once I add tons of foliage and trees on the landscape. and not speaking of baking lights(!!!) which is a nightmare.
It seems like they have still not fixed this in the release.
Yeah shader compiling is annoying, even with a reasonable CPU, addequate RAM, and GPU it takes a lot of the fun out of developing. Would be useful to know what could be done to speed this up.
Only started learning UE5 last week and would love to know a solution to this as well, just seems really unoptimised to me coming from other 3D software, and as you said just makes it virtually unusable.
Unreal is heading to the old problem of CGI industry, which is forcing developers to end up renting render farms by the hour on the Cloud… Or going back to the days of Silicon Graphics where you will pay a house to be able to buy a machine capable of rendering your project.
Faced the same problem, UE5 shaders compile A LOT slower compared to UE4.25. This makes it unusable for me to make the jump to UE5 just yet, despite having great interest in nanite & lumen.
Solutions found online didn’t help for me; such as in reddit where some user recommend editing the “WorkerProcessPriority=0” or “NumUnusedShaderCompilingThreads=0” within “Program Files\Epic Games\UE_5.0\Engine\Config\BaseEngine.ini”.
Hope someone from Epic can explain. Or do users need to upgrade to more powerful machines in order to use UE5 for the same things we can do in UE4?
Brand new computer, specs match or exceed everything recommended for UE5. Had the professional who built it search for why compiling shaders now take forever. (25 min. for 6,500)
Is anyone at Epic paying attention to this? It’s almost impossible to multitask now. It needs to be remedied.
I added more RAM to my machine and that made a tremendous difference.
Same thing happening here. Pretty simple project using a couple of quixel megascans and a texture. I’ve noticed this happened when I enabled Hardware Ray Tracing. Before that, there was no problem at all.
