I've noticed in a d3d9 game (I don't say the name to avoid any problem, but if a moderator asks I'll say it) this thing:

I'm trying to make a wallhack using the zBuffer trick but I guess the developers made a fix, and I don't know how they did it... let me explain, when I change the zBuffer of a playermodel, I can see him behind some walls, but I can't behind some others but instead if I delete the texture of the wall to see behind it, I still can't see the player model but I see his shadow << that's the key I guess, I can see his shadow, but I don't understand what it means... why direct3d would display a shadow of a model that doesn't exists? So my guess is like if they made a function that gives the player a transparent texture if he is behind certain walls or what?

I guess at0mos maybe has a clue of what might be happening, thank you.

In some games, the entity data isn't given to you if the player is behind enough things or far enough away that the server deems you out of range and don't need the data. It could be the fact that you aren't seeing them because of something like this. An example of a game that does this, CSGO. They started doing server sided visibility checks and such to prevent most wallhacks and ESP from working from far distances.

There are other means of getting the data needed to see players from other distances though such as sound information or other physics engine data that may relate to another player. If you still see the shadow, or if you have the player information you could just draw your own skeleton/textures to render the model yourself.

Other things to check if you do have the data is the depth buffer, render states, and to make sure that you are properly altering all layers between yourself and the player.

It's hard to say without knowing what game it is, but given that its online based on what you are saying you can't name it here otherwise it'd break the rules and this thread would be locked.

That said, play around with monitoring the other player data to make sure it is or isn't staying updated based on distance and depth behind objects to rule out if that is even something to worry about.

Outside of that, making things show up over other stuff is mainly a matter of altering the render states of the specific object, in your case the player model and anything attached to it (so you'd need to get the information for not just the player model but anything attached like their gun, radio, bomb, hats/helmets, etc.)

In most cases it's just done by disabling the Z render state before drawing the object that you deemed the player model and anything attached to it.
