I know it has been discussed here so many times, but I simply can’t find any solution to my problem. Every time I want to put some material or mesh or anything else in my map, it alwayse takes too long (about 1 minute) and this is happening even in case I’m working with simple things. It’s much worse with difficult ones. I downloaded some materials for begginers in Marketplace (Open world demo collection), I know it is much harder for computer to work with it, because it’s much complicated, but approximately 10 mins is a really long time for one ‘‘rock’’.
There are usually about 350 shaders being compiled.
I’m using UE 4.10 and 4.11 and it’s always the same…
Thanks for your help…

its not the compiling of shaders that is way too slow.
Its actually your computer that is too slow.
The suggested (minimal) cpu speed is quad core, 2.5 ghz.
only 8b of ram is just cutting it.
not to mention that your gpu is… well… rather lacking oomph.
the open world demo collection was made for ultra high end computers with top of the line cpu’s, nvidia titan gpu’s, 32-64 gb’s of ram, has 4096 & 8192 resolution textures that will flood that little bit of ram you have.
Its better with your low end specs to use the infinity blade content, which is made for mobile.
and since your laptop-esque computer thing has specs that resemble close to current gen mobile devices…
thats what you should focus on unless you can dish out 1500-3000 dollar for a new pc.
Thank you for your answer. I’m just a fan of creating environments and so on. I’m not developer or something like that so I will try the infinity blade content.
Thanks
If you arent contributing to an already answered question, please dont re-open it.
This was closed quite a while ago.
Also, 8gb is the very minimum and therefore can cause quite some slowdowns.
A simple material change from basic red to blue on a cube primitive takes at least a minute and a half to compile the shaders, and I know my computer isn’t slow. 1080ti, i7 5960X, 64gb RAM, etc. I’ve been having this problem on and off, and the only fix I can find for it is restarting UE4.
While compiling the shaders, I’ve seen that my CPU usage doesn’t even hit 40%, and RAM usage is negligible, so UE4 isn’t even using resources properly.
I know this thread is rather old, but I figure I’d contribute. I would, in whatever way possible, work to create material instances.
In your materials you should use Parameters instead of just inputting things - using a texture sample is basically like hard coding. Instead use a Param2D.
Instead of applying the material itself to your meshes, just use the material instance. Changes you make to the parameters in a material instance happen instantly and are reflected in the game world right away!
You can set parameters for most values you would want to continuously change and tweak.
After you’ve created your instances that should be the last time you ever have to watch the engine compile your shaders!
