Shaders compile after every material alteration

Maybe this is not a bug, but it seems to me like one. When I am working in the material editor and for example change the value of a varible then the whole shader starts to compile even if I don’t want him to, because I didn’t finish my work. This goes on the whole time to every change I make he starts another compilation. It stacks and stacks up to over 7000 often and then I have to wait 30 minutes or so…

This thread is about the same I think:

Hi ,

Can you provide your dxdiag as well as reproduction steps for us to further assist you? Thus far I have been unable to reproduce this on my end. Thank you!

A showcase video… the password is: unreal

https://www.firedrive.com/file/18D9934C9AACC54F

You should be able to access it now … it was password protected, but the password was listed above

I made it public now…

I am also uploading it in form of an .rar at the moment. I hope you don’t need a . file.

That will take some time…it’s a 3.5 gb video, because of an error I can’t encode it…

Hi ,

Unfortunately I could not access the site, would you please upload the video to a . file and paste that here? Thank you!

Hi ,

Can you upload it to ? That may be a more efficient method. Thank you!

Hi ,

Unfortunately firedrive is not a designated website that we can access. We are more than willing to assist you further, however we will need the video to be uploaded to a website such as or vimeo so that we can help you assess the problem. As soon as the video is up please let us know so we can watch it and see what may be going on. Thank you!

Interesting that you cannot access it, it’s a standard website like . However…
