Maybe a feature related to asset conversion. If the tool allows converting assets from one game to another (like from Half-Life to S.T.A.L.K.E.R.), that could be useful. But the user mentioned "Portal," so maybe integrating a physics-based puzzle system, similar to the game Portal? Wait, but S.T.A.L.K.E.R. is a survival horror game, so adding a portal mechanic might be a stretch. Perhaps the user is referring to a different sort of portal system, like teleportation or quick travel?
Now, the user is asking for a feature for this. I need to come up with a specific feature that could enhance the functionality of this tool. Let's think about what users might want. Modding tools often need more efficient ways to handle assets, better scripting, or improved user interface. stalker portal player for pc v71 by sahbaz work
