Hey @Solya_Minor!
I do have to ask what you mean by this? It’s 100% based around the size of your navmesh, if it’s too big you need to focus on making your invoker idea work because that would limit the size necessary, then use dynamic on top of that. You can also lower the refresh rate of the dynamic Navmesh to also lower the overhead.
But the problem here lies in the name itself, you see. “Static” and “Dynamic” literally mean “unchangeable” and “changeable”. 
Why don’t we focus on getting your invoker to work? Get back to us on that, what is happening there, why isn’t it working?
