Hello!

A simple shader takes between 5 to 20 minute compilation it’s me.
This is huge!
Is there a way to decrease the time of compilation?

Thank you for your response.

Bonjour!

Un shader simple prend entre 5 à 20 minutes compilation c’est moi.
Ce qui est énorme!
Est-il possible de réduire le temps de compilation?

Merci de vos réaction.

it’s normally to take so long while you’re using a dual core CPU

UE4 recommended cpu is quad core processor

best of luck!

It is obvius it needs a button to compile the shaders on demand because all my sistem is blocked, for example it started to build shader then the autosave started then nothing, It just crashed. I think my system is quite good it’s a dell inspiron core I7 with 6 Gb in Ram and ATI 2048 Mb Video Card Laptop, Games like Skyrim works with full graphic details without problem, Compiling a software with 7000 lines of code is not a problem and here it crashes on some asset shaders :frowning:

Hi Ion,

Loux’s issue was caused by running UE4 on a dual-processor. If you are having an issue with compiling shaders I would suggest upgrading to 4.2.1 and if you have already upgraded, please feel free to post a new question/feature request under Bug Reports.

Thanks, TJ
