Just upgrade Unity and my bundel comes in but the shaders are blank. Texture name is there but in scène everything is pink. Of i manualy set shaders to standaard everything is fine. Unfortunate you can nog select all imported objects and set their shaders, thuis component disapears when multiple selecting

it still happend on 5.5.2f1

Why has this been resolved when it isn't fixed? This is still occurring on my version 5.4.3f1 (pro).

Please can someone respond rather than ignoring the issue for the last two years and then falsely claiming it is fixed.

Is it fixed with 5.4 version of Unity?? Still i'm facing this issue!!

This issue is not fixed. Please do not resolve issues that are still broken.

Besides making sure that or Asset Bundle is built for your target platform, you need to make sure to clean the Asset Bundle cache from the previous time you downloaded it.

I am using 5.5.0f3, and I always had this issue when using Asset Bundles. I fixed the issue today, by doing a couple of things:

1. I made sure that the shader that I wanted to use was included in the Asset Bundle (I have a custom Standard Surface Shader);
2. I made sure that I am building my Asset Bundle for my target platform (In my case, I am working on a Windows machine, targeting Windows 64);
3. I included my custom shader to the "Always Included Shaders" list inside the Project Settings -> Graphics;
4. I cleaned my Asset Bundle cache by running "Caching.CleanCache()" from an Editor script;
5. Built Asset Bundle;

Hope that helps someone =)

This has not been resolved in Unity 5.4.

I'm still having this issue on Unity 5.4.1f1, I tried the workaround suggested by OMAR_UNITY, but no luck with it.
Since this is a problem that only happens on the editor for me, one workaround that worked was to add some lines of code only for when in the editor, where the asset loaded from AB would have its shader re-set by its name:

#if UNITY_EDITOR
foreach(Material material in [rendererLoadedAssetBundle].materials)
{
material.shader = Shader.Find(material.shader.name);
}
#endif

Maybe this issue is related to the fact that almost the same thing happens with sound sources loaded from asset bundles in the editor. They are loaded without errors, but their references to the audio mixer groups are broken, even though the naming of the references looks correct.

This is not resolved. Still exists in 5.4.1f1
