Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Multiplayer variable replication: Client "Accessed none"?

I am learning the basics of UE4 networking and preparing my game for multiplayer:

A character has a variable "healthbarMaterial" (Type: Dynamic MaterialInstance). The Material is set to an Instance of a Material i created on the construction event.

Running the level on serverside works fine, on a client somehow my variable is not synced. "healthbarMaterial is set to "replicate". I am pretty sure i missed some pretty basic stuff here.

The following error occurs in the Message Log: alt text

ConstructionEvent of Actor Z_Unit:

alt text

This is the corresponding function "HandleHealthbar":

alt text

Settings for variable "HealthbarMaterial": alt text

Product Version: UE 4.9

You don't need to replicate anything graphics related, client should handle that based on game data he have from gameplay replication. I kind of susspecting server actully replicates none due fact it does not run rendering if you do dedicated, thats why you got errors

It is not dedicated, i run two windows, one client and one server.

Changing the material to be applied on both, server and client without replicating fixet it. But somehow that does not fix the fact, that the replication for Dynamic Material Instances is somehow broken?

Otherwise if UE4 does not support replicating Material Instances, it should say that in it's documentation.
