The **GetDynamicMaterial** node (found in widget blueprint library) is expecting an in/out parameter by reference of a brush, but is missing the **UPARAM(ref)** attribute to make it valid. > **[Get Dynamic Material](https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Widget/Brush/GetDynamicMaterial/)** > > Get Dynamic Material The documentation also shows it broken. ---

Hi Grogger - Yep that’s not right. I have placed a bug report in as UE-18241. In the meantime, if you call a reference to a specific brush you can then call the Get Dynamic Material node and if will be the accessible one. Thank You Eric Ketchum ---
