Copy/Pasting material expession graph renames nodes

While doing the Creating a Fluid surface with Blueprints and Render Targets tutorial, i came across a regression/bug/different behaviour in 4.15 compared to engine version 4.14 and 4.13

The tutorial allows you to copy/paste material expression graphs and pasting the HeightSim-material in version 4.15 renames the texture parameters. See attached pictures.

This breaks the tutorial and I am not sure if this is intended behaviour. If this is intended, there should be a note for the tutorial to manually rename those affected nodes for [this tutorial][3] when using engine verison 4.15

Hi ,

Just to let you know there is a JIRA for tracking this, UE-43159, although I’m not sure what the targeted release date is just yet. We’ve seen this internally too so I’ve requested the priority get bumped if possible.

EDIT: Looks like this is going to come through in 4.16.

Thanks,

, I can’t find the issue number in the issue tracker, is this a bug or is it invisble? But thanks for letting me know :slight_smile:

No problem. I requested it be made public but it can take a while to appear sometimes, it should be there on the tracker once it does.
