Navmesh and moving floor

Hi everyone,

Being pretty new to UE4, I need you help to help me solve an issue I am facing since yesterday.

I am actually working on a VR (HTC VIve) game using the provided VR template using the motion controller locomotion system.

My goal is to make the ground to fall down at a certain time. In order to do this, I have to set the ground, which is an CTOR bp, to “movable”.

From the moment I set this BP as “movable, the navmesh is broken and I can no longer TP anywhere.

Does anyone have an idea on how to solve this?

Many thanks in advance for your precious help.

try setting your project settings to have dynamic navmesh instead of Static
