Some materials won't work on destructible object

Hi,
I’m using UE4.12.5 and some materials don’t work on a destructible object and I can’t understand why.

My object with a working and a not working material applied to it:

My first material shader (the working one):

The other material:

Is the emissive node that is causing this issue or the opacity one? I also saw that second material instances won’t work even if the emissive color is multiplied by 0.

Edit:
I confirmed that the emissive color node is the cause of my issue. If I unplug it from the material it works fine.

Hi Ricky,

Check in your material that the Usage is set for “Used with Skeletal Meshes”. If it’s not it will not be compiled for use with things like Destructibles. You can check this by selecting the Main Material Attributes and scrolling down to the Usage section.

In my test it worked as I would expect unless this was disabled.

Thank you, I didn’t notice that.
