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"

[Closed] [BUG] Apex not working

Am a little confused with Apex. I will explain the exact steps i did:

Yesterday:

1: I imported a building model into PhysX Lab.

2: Used Voronoi as fracture method and broke it into 1000 Pieces.

3: Exported it as APB.

4: Imported into Rocket and adjusted the below settings:

 Damage Threshold: 25.0
 Impact Damage: 0.0
 Support Depth: 2
 Impact Damage Override: IDO_Off

5: I used a Blueprint to deal damage and VOILA!! It does work the way i wanted! :D

Today:

1: I imported another model into PhysX Lab.

2: Used Voronoi as fracture and broke into 1000 pieces.

3: In PhysX Lab selected some chunks and made them as support.

4: Exported the asset and imported into Rocket.

5: Opened it up and first thing i noticed was BodySetup was None.

6: Anyway i ignored it and set the Apex settings as mentioned above.

7: Using that same blueprint i gave it some damage and VOILA!! It didnt work. :(

Retrying:

8: Again i went into PhysX Lab and reimported the mesh and broke it again.

9: This time i didnt select any support chunks.

10: Exported and re-imported (Right-Click and reimport) and still BodySetup was None.

11: So i deleted the mesh from Content Browser and imported again.

12: This time BodySetup was NOT set to none. So i assume it will work in-game.

13: I used that same blueprint to deal damage and VOILA!! Its still not working. :(

I have attached the asset here incase you want to look.

NOTE: Am using PhysX Lab version 1.1 that uses Apex SDK 1.2.1 and PhysX SDK 2.8.4

I have found that a good node to use for applying damage to a destructible mesh is Apply Radius Damage. Shown below is a screenshot I have taken from within a modified version of the MyProjectile blueprint in the FirstPerson Blueprint template.

alt text

In addition to this, there are also properties in the Details panels of the Destructible actor and for your projectile called "Use Async Scene" and "Check Async Scene on Move" respectively. Please make sure that your choice to either have this enabled or disabled is consistent between the two. Having one enabled and one disabled can cause the issue you see.

I hope this information helps, let us know your results.

Cheers!

Hi Satheesh,

When you say that the asset is "not working", do you mean that it is not being destroyed at all?

I have used your asset in ShooterGame and do not experience any issue; when shot, it breaks into pieces where shot.

Yes its not destroying at all. I tried setting the base damage to 300 and Impulse to 50 and still nothing happens. Not even a single chunk breaks free. I attached a particle effect as fracture effect and when shot that particle also doesnt show up. Any idea what might be the issue?

Note: My project is 100% Blueprint only. No C++ codes.

Just now I imported another mesh and still its not working properly. This time only the below half is breaking up. I have attached the apex asset here. I have recorded a video and uploaded to FTP_Dropbox\RyanJon2040\apex_issue.mp4. Kindly look into it. And please do let me know if you want me to upload anything else.

PS: I am unable to upload the video here because it says size exceeded. Even though its just 8 MB.

Apparently the projectiles seems to pass through the mesh. Causing no damage or anything.

I did mention this in this post here - https://rocket.unrealengine.com/questions/1647/apex-destructables-collision-problems.html

and here https://rocket.unrealengine.com/questions/7541/apex-destructible-error-rocket-stops-responding.html

where Stephen you did respond - "Regarding the rocket launcher not affecting DestructibleMeshes, I do not yet have a definite answer for that. I have tested and discovered that actors do not register "damage" when shot by the launcher (although characters are affected). I have reported this issue for investigation."

I'm sure Epic will get us an answer soon :)
