Just fix the bloody issue already. I can't believe that this is still not fixed after the new update... I'm using particle effects infront of the damn camera as a substitute to fade the screen to black. And it doesn't work most of the time.

Just to add my two pennyworth....this issue is driving me nuts! All my Unity work involves a huge amount of texture/materials and just plain object animations. Mecanim is useless for my purposes. The legacy animation system when it worked was not brilliant but it did work. PLEASE can it be fixed.

I used Animator component, material properties are still greyed out in Animation window.

I hope someone from Unity is still reading this.

How many comments like this below do you need to make it work again ?
I understand that you don't want to update it anymore - but can you at least make it usable as it was before ?

You make some poll on a home page and ask - how many people actually use it and need this ?
That will give you some picture if it's worth the effort - seriously.

Seriously? That's pretty terrible...

The games we make (The Room series) has lots and lots of objects in every scene which need to have simple animations on (doors opening, objects spinning, etc). The old animation system is great for this - no messing around with state machines, just make an animation, call Play on it (or have it play on awake), and away you go. The new system is a huge pain in the arse for that sort of thing.

The attitude of "yeah, well, we'll just leave it in there, rotting, until it's in such a bad state that no-one can possible use it any more, at which point we'll delete it" is sucky at best.

Please please please either make an official way of doing simple state-machine-less animation, or keep maintaining the old one.

The "fix," where you are able to change properties by switching between your animation keyframe and the inspector's material editor itself, is apparently fine for colors, but it still doesn't seem to work for the alpha. So, still no fading in and out via a convenient animation curve.

This is really disappointing. I wanted to quickly make an animation clip to fade the material's alpha in and out. The animation window lets you draw in the curves but it makes no difference to the material... it just doesn't work anymore. So, now I'm supposed to use Animator? I just wanted to do a simple material change over time. Thanks for killing a simple and useful tool Unity.
