Problem with animation material parameters in Unity4.3

I'm trying to animate the renderer's param with animation, like the color of the material. It works well in 4.2, but after a upgrade the unity3D to 4.3, it can't work anymore.

I can animate the transform, position or else.

When I try to animate a color param of my material, the old param in the inspector became red, I don't know what's that means.It seems like everything work correctly by the curves, but the color never changed.

Is that a bug of 4.3?

 

I also have this problem. Old animation still works, but I can not author a new one with material animation

 

Heya guys.. I've made a small tutorial for you, on how to animate material properties in 4.3

hope it helps...

 

Hi Instruct9r; thanks for the quick video on the new animator. But like the others, I think the main problem is that legacy animations are not modifiable anymore if they involve material/renderer animation. I'm assuming it's a bug...

 

I'm having the same prob. Did anyone already submit a bug report?

 

Hi,

I think I've encounter this issue too.

In this attachment, I've selected on a legacy animation material I've animated in earlier version where by I can animate the texture offset easily from animation editor.

I can't be able to use the animation editor to animate texture offset now. I believe there's some other missing attributes too. But texture offset is the most obvious at the moment.


Texture offset can't be found in animation editor of unity 4.3 now.

 

This is 100% most definitely a bug/issue.

The necessary parameters for editing "OFFSET" and "TILING" simply do not exist in Unity 4.3, thus making it impossible to edit/create UV animations targeting materials. This is evidenced by the red highlight when you attempt to edit a UV anim from 4.2.

Bummer

Hope Unity gets on this and fixes this . Making UV mesh animations used to be really slick, something that could be done in mere minutes.

 

I've found a reported bug http://issuetracker.unity3d.com/issues/texture-offset-properties. Vote if you want to have it fixed asap.

 

Ya, this really sucks. Definitely a huge obstacle for me in late-stage work on FRACT OSC. Please fix this Unity, this one is no fun

 

you can set as below

 

I found the solution!!!! Well, another user did, but I'm posting it!

The problem is that Unity has changed its Material keyframe formatting when it saves animation clips. If you need to use the legacy animation system here's how to fix it:

Change animation type to 1
open the clip in a text editor, and replace classID 23 with classID 21
Still in the text editor, remove material. from the beginning of each Material attribute

Please post if this worked or didn't work for you. And spread the word!

Using Unity 4.3.4 and am running into a similar issue trying to animate a float property on a custom shader. I can create a curve, but it doesn't affect the material at all whether in edit mode or playing. This worked fine in versions prior to the new Animation window. I've created a stripped down example of the project and have submitted it as a bug.

 

I also noticed that problem upon upgrade, but, at least about the texture Offset, I think that it only changed menu. I found it in this option: Material._Main Tex_ST
There you can animate the Offset and tiles.

 

1. I don't have scroll bars in the curve window that allows me to scroll around to see my curve. If I want to make a big curve I can't scroll up or down to reach the value to which I want to drag the keyframe.

2. I can'T set my animations to anything shorter that 1 second.

I have Unity Pro 4.3.4 on OSX 10.8.5. The previous version of Unity did not have these problems.




Forget it. Restarting Unity fixed it and I found to shorten the animation length that you have to do it in the Dope Sheet.

 

this is not fixed yet??

 

It looks like this BUG has not been fixed, or there is just another regression in 4.6.1p1

 

same problem with me, unable to animate the material properties.

 

Same problem...
1.) I am unable to put new keyframes to Legacy animations, altough I am able to move existing keys. This clips are palys well.
2.) Material offset / tiling are not working in the new animation type.
3.) The new animation type doesn't support material blocks You can not animate even the colors separately.

Based on the trick with changing ID's, I made a small tool that can switch between the two types of animations ( legacy and mecanim), to both directions. This means that I can switch an old animation to mecanim type, able to modify and switch it back, so it will animate fine. The only thing I can not solve yet is the animating of mateiral blocks as seems they are not exist in the mecanim animation clip.

 

I have a different problem. I'm animating the color of a material. Now, I want to adjust another renderer's alpha in relation to the animated material color. So, I want to get the current main color ("_Color"). However, I can't find a way to get the current color that the editor is showing. Neither combination of the following works: sharedMaterial, material, color, GetColor("_Color"), querying in Update, querying in LateUpdate.

Someone else has had this problem, too: http://answers.unity3d.com/questions/935784/after-animating-a-custom-materialshader-parameter.html

Is there really no way we can get the current main color of a renderer, which is animated by an animator?

Ok, sorry, found the answer myself:

The way to hack-fix it mentioned by sterlingr works.
But you have to enable textual asset serialization.
In fact, we can do it in script (for example, an implementation of AssetPostProcessor).
Here is code snippet of a context menu implementation.
It only works in Unity 4.x. The hack won't work in Unity 5.x .

*I coded it in Unity 5.x, you may have to do some modification in Unity 4.x*

Code (CSharp):

1. public static class LegacyAnimationFixer
2. {
3.     [MenuItem("Assets/Convert to Legacy Animation", validate = true)]
4.     static bool CanConvert()
5.     {
6.         bool canConvert = false;
7.  
8.         foreach (var obj in Selection.objects)
9.         {
10.             if (obj is AnimationClip)
11.                 canConvert = true;
12.         }
13.  
14.         return canConvert;
15.     }
16.  
17.     [MenuItem("Assets/Convert to Legacy Animation", validate = false)]
18.     static void ConvertToLegacyAnim()
19.     {
20.         foreach (var obj in Selection.objects)
21.         {
22.             AnimationClip clip = obj as AnimationClip;
23.             if (clip != null)
24.                 DoConvert(clip);
25.         }

I can't believe this bug still hasn't been fixed??
The fix mentioned by sterlingr and your script G1NurX both work around the issue somewhat, however artists can't really properly author or test legacy UV animations within unity while this bug exists (unless I'm missing something?)

It would be nice if this bug could be fixed, after being reported over 2 years ago....
