Hello!
I found that in this doc https://rocket.unrealengine.com/docs/ue4/INT/Engine/Subsystems/Rendering/MaterialsAndTextures/Materials/MaterialInstances/index.html#materialinstancedynamic, “Create Dynamic Material Instance” (Build 1945001) node named as “Create MID” and “Make MID For Material” (on screenshot).
Sorry, but I spend some time to understand whats wrong.
Also, when you click on “Material Instance Dynamic” link in table of contents, it scrolls page a little bit lower than description starts. (Chrome)
I think it should be updated.
Thank you!
