Simulate Physics #38

Open Pikike opened 1 month ago

Pikike commented 1 month ago

Hi, I want to simulate physics on the meshes i imported with assimp, but i just can't make it work. Also i would love to interact with the objects, an i've already added a sphere collison, with blueprint to the actor i will use, but it's not working.

So first I created an actor, and added a static mesh with hidden in game render option so it is basically just a placeholder, but with this help i could the actors simulate physics set true. After i added to this actor a procedural mesh component, and the physics worked properly. But if i add the procedural mesh component through blueprint like i've seen here ( https://blueprintue.com/blueprint/inhg2zu3/ ) the physics wont work.

If you could please help me and if you need more information just let me know.

there is an option to create static meshes from AIMesh type of the assimp image this one generates a collision for the import. (not generated by my code but its unreal that creates collision).

So instead of using get mesh data for procedural mesh node i should juct use get static mesh node?

irajsb commented 1 month ago

yeah. its even more efficient to draw

And with wich kind of node should i replace add procedural mesh component node and create mesh section node? Currently the blueprint looks like this: image
