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"

Instanced Static Meshes are invisible in ChildActor or get invisible on add something to array

Hey Guys,

i work with Instanced Static Meshes + Hierachical. Since 4.18 i have a Problem.

Imagine i create an Blueprint Actor and add an ISM. I save and compile. Now i create a Child Actor of my new created Blueprint. In Content Browser Preview Window everything looks fine, but as soon as i click on the child actor all ISM or HSM are not renderd. Not even in wireframe Mode. But the Array and Setup is correct filled (from parent actor).

the worst part is, that it happens also to and exisiting ISM Array. As soon you add something to array, all actor get invisible.

That's how it should look like Any Ideas?`

ah allright, i can do that.

maybe the wrong place here is it based on a ticket system? Cause sometimes (like here) people figure out a workaround or fix it by them selves.

There is an workaround, for the Child Actor Problem. (Thanks Irakli G.) Just take the inherited Actor and add a new Instance to the Array. Et voilá they pop up again.

You can delete the new created instance again, after fixing it.
