Spline Decals?

Thanks, I tryied to recreate the material of this doc (with runtime virtual texture volume set with a runtime virtual texture asset, etc) and the result is a full black material https://docs.unrealengine.com/en-US/…ime/index.html
When switching to shader model 4 (which I guess doesn’t support virtual texture) the material works, as intended by the feature switch node but as soon as I switch back to shader model 5, the material is full black.
