Changing material at runtime

WiseKodama

Greetings,

Can someone advise me on how I can change materials at runtime?

I've added the define I found on github:

#define SPINE_OPTIONAL_MATERIALOVERRIDE

Code that runs at runtime

var meshRenderer = skeletonAnimation.GetComponent<MeshRenderer>();
originalMaterialInstance = meshRenderer.material;
slowDownMaterialInstance.SetTexture( "_MainTex", originalMaterialInstance.GetTexture( "_MainTex" ) );
skeletonAnimation.CustomMaterialOverride.Add( originalMaterialInstance, slowDownMaterialInstance );

Nothing seems to change and I am a bit stumped

Check out the MaterialReplacementExample.cs that is included with the spine-unity runtime. It shows how to set the material as well as apply values from a Material Property Block :yes:

Also - you shouldn't need that #define. I've never heard of that one though, so I'm not sure the context.

Ah, I don't seem to have that .cs file. We are using version 3.8, perhaps this was introduced in a newer version?

Possibly yeah, maybe the example was added later. You can download the newest runtime and just grab the script out of it and see if it works - I feel pretty confident that it'd still work with 3.8.

That did the trick. Thanks so much!

Glad you've figured it out, thanks very much Jamez0r for helping out! 8)

The first place to look should always be the spine-unity documentation pages:
spine-unity Runtime Documentation: Materials
There is also an FAQ section for frequent questions.

Actually it was present in 3.7 already:
https://github.com/EsotericSoftware/spine-runtimes/blob/3.7/spine-unity/Assets/Spine%20Examples/Scripts/MaterialReplacementExample.cs
Perhaps you didn't import everything from the Spine Examples directory of the unitypackage.

I've added the define I found on github:

You don't need to set any defines. If that were necessary, it would be mentioned on the spine-unity documentation page. 🙂
