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"

Remove Player Collision from Destructable Mesh After Fracture.

I'm trying to make the player be able to break objects, which works with destructable meshes.

However, How can I make the fractured chunks no longer collide with the player? Before destruction I want collision standard, Afterwards when the mesh is fractured I want the player to be able to walk through the chunks.

Is there a way to do this with Blueprints or is there a specific setting I need to change? Thanks!

What I'm trying to achieve summed up:

  • Not Fractured Mesh = Collides with Player.

  • Fracture Mesh = Player doesn't collide and can pass through.

Product Version: UE 4.10

I would rephrase it a little:

Is there an option to separate "chunks collision" and "non-fractured mesh parts/chunks that are part of world support"

What you can do here:

a) Setting the "Large Chunk Threshold" inside a DM that is placed in your map (you can't do it inside the DM itself) the higher the setting, the more you get a chance to run through chunks. https://www.youtube.com/watch?v=RnCWbUNaG7A

b) setting the DM collision settings in the detail panel from "Destructible" to either "IgnorePawn" or "Custom", setting up any collision.

About using Blueprints: On some threads people say that using DM inside BP's are bugged. There is an OnComponentFracture component but i can't tell you how to use it. As far as i know there is no proper way to access the chunks inside BP.

At the moment i wouldn't count on any future feature updates..i am digging through the forums and answer hub for three sleepless days now because of several issues we got during the creation of gameplay elements that involve setting up destructible meshes.

Most problems/issues + features are either backlogged since 2014 or exist as ticket somewhere deep on the "not a priority" list.

I hope this answer helps you.

Best, Tobias
