Huge WebGL build size in 5.6 vs 5.4

Unity Engine
1

Anybody knows if the next release will address the build size issue?

I spend weeks pain stakingly reducing my build size with 5.4, but when i upgrade to 5.6 the build size is now 40 Meg larger, and scene asset bundles has become 10 meg larger.

So i end up going back to 5.40b24 because larger builds takes longer to load and longer to change scenes.

Anybody knows if this will be fixed in the next release?

Have you filed a bug report?

That should not happen. Please file a bug report with your repro project and ping the case number here.

I Googled it for you here.

Do you have any Shaders listed in “Always include Shaders” in your Graphics Settings? Unity 5.5 will generate many more shader variants (to support new rendering features), which can increase the build size a lot for included shaders.

Hello Jonas,

Yes matter of fact I do have 13 shaders listed in the “always included shaders”, so how can i get rid of the additional 40Meg of build size and 10 meg of scene asset bundle size when building with 5.6?

Dont know much about shaders, but 40 Meg of shaders seems like a lot!

Thanks

You must check your Editor.log file after a build to see the size of your textures,models,sounds ect …

As @roka wrote, check your Editor.log for a breakdown. But, 40 MB for 13 shaders is quite realistic, unfortunately. When you add shaders to “always included shaders”, Unity cannot know which permutations to include - which can mean “quite a lot of them”. See this blog post by Aras for context: http://aras-p.info/blog/2017/02/05/Every-Possible-Scalability-Limit-Will-Be-Reached/

So, best, try to avoid using “always included shaders” if you can.
