CPU particle collision only works with static meshes?

I have a CPU particle effect with collision which works fine with static meshes but whenever I set a mesh to movable
the particles no longer collide.

Is this expected behavior or a bug?

Im currently using 4.4.3.

Hi Opamp77,

Under the Collision section, in the Details panel, what is your Collision Types set for?

You can click the + sign and add different types of geometry that you want the particles to interact with (WorldDynamic, WorldStatic, Destructible, etc.)

You didnt specify which details panel.

The details panel within cascade under the collision module has no such options.
My mesh is setup to block everything.
But I cant find anything that looks like the picture you posted.

Cheers.

Sorry about that Opamp77. I thought it had already been implemented, this is the fix for the issue from our newest internal build. You will see this option in a future update.

In the meantime, I will continue to search for a possible solution in 4.4.3.

Try this solution.

  • Click the movable Static Mesh in the level that you want the particles to collide with

  • In the Details panel, change the Collision Presets to Custom

  • Just below that, change Object Type to WorldStatic

The object itself should stay movable, just the collision channels will change.

Many Thanks.
