Generating navmeshes

[jesst3r]

Greetings, is it possible to generate server navmeshes for Unreal Engine 4? Thank you!

UE4 and KBE, all use RecastNavigation to navigate:

2: This is a mmorpg commercial project using UE4 and KBE.
In KBE do some compatibility, based on the first one.

3: Use the command(ExportNavigation) of UE4, Export the obj file, and then use the RecastNavigation tool to generate navmesh.

这个项目是啥意思？这个需要修改ue4的源码的

[kbengine]

static class FNavigationGeomExec : private FSelfRegisteringExec
{
public:
/** Console commands, see embeded usage statement /
virtual bool Exec( UWorld InWorld, const TCHAR Cmd, FOutputDevice& Ar ) override
{
#if ALLOW_DEBUG_FILES && !(UE_BUILD_SHIPPING || UE_BUILD_TEST)
bool bCorrectCmd = FParse::Command(&Cmd, TEXT("ExportNavigation"));

Morning folks,

There is a command named "ExportNavigation" which generates a navigation mesh for recast which you can later use to export a bin file from -> https://imgur.com/4IfO5Pv

Cheers.

@H1X4Dev ,
Hi, may I know where does this screen shot from? Is it from UE4 or KBE?

[H1X4Dev]

@husha1993 That's UE4.

@H1X4Dev Thanks.
I typed the "ExportNavigation" in the ue4 command console and it generated a .obj file.
While I tried to open the .obj in blender, I found nothing(mesh) displayed.
Have you tried to open the .obj file showed in the screen shot?
May I know how do you export a bin file from the .obj file?
