Hi, i have a working svn server but when in the editor i can only checkin unreal specific files and not externally modified sources like png, fbx, tga… Is there any way to do that without using external tool ? Thanks !

No sorry, the UE4 Source Control is only dealing with what the Editor can open: Content/ assets (BP, Materials, Sounds, AI, Maps…) Config/ files and the uproject file. Edit: speaking with the experience of authoring the UE4 Git plugin. Cheers
