Why do I have "MaterialPropertyBlock is used to modify these values" on all materials?

I've just noticed that all materials in my project show this warning. I can't think of anything weird I'm doing. Most of my objects are 2D sprites with the original Sprites-Default material. Some sprites have a particle shader, which is not strictly speaking made for the Sprite Renderer, but still works fine.

When I create a new empty sprite, the Sprites-Default material gets assigned, everything is normal. When I now add one of my sprite assets to the Sprite Renderer, the warning appears in the material inspector.

I am not using the MaterialBlock API in code and I'm not animating the materials via the Animator. At least, not that I know of.

 

Thanks, that does sound logical. So it's not a real issue. Still, it is weird, that it shows as a warning, always looks like something went wrong.

I think it makes a lot of sense, that the warning shows, when using the regular particle material, since like you explained, the _MainTex slot will be overridden by the sprite, but the warning also shows on a regular sprite with the default sprite material, where there's no ambiguity between which texture is used.

 

I have got the remark on animtated material in unity5.6.0f3 and unity5.6.0p1 also.

I change the color of material with animator.

What is your recommend?
Am I have keep an eye on the remark?

 

Changing material properties in animations also work with MaterialPropertyBlocks.

 

The images I am using to animate my material are Textures and not Sprites, so why am I getting this error

 

Doesn't matter. MaterialPropertyBlock is something that works with any renderer(perhaps short of CanvasRenderer,not 100% sure there). Just so happened that OP was using a SpriteRenderer.
Are you trying to change the texture through code as well as through animation clip?

Read this to understand MaterialPropertyBlocks better. Using them will make rendering faster and it's something that's used under the hood in some parts like animations,by default.

 

No, just animation clip.

 

Does the error show up in Console? Or on the inspector?

 

Inspector

 

It's not an error then.As you can see from the link in my previous response, this is something that's there as a warning. Since you're modifying something in an animation clip, it warns you that you basically can't modify that property in code. If I remember correctly, trying to change the value through code will compile and play without errors, but since a value is being changed through animation clip it has higher priority so any changes through code are going to be overritten by the animation clip.

 

Wait, are you saying that I SHOULD be able to animate it?

I'm not coding anything.

 

Yes ,unless I'm misunderstanding something,you should. MaterialPropertyBlocks is just what's used to store values in certain cases when animating stuff.

 

Okay, I'd like to DM you about my current issue if thats okay

 

npatch... Thanks for including the link to the article on materialipropertyblocks . Article was helpful.
