Currently, I'm trying to make a gun consisting of a 3d model. The blender's and the GZDoom's cameras are all set to 90 degrees. This means, theoretically, they are identical to each other. So, I quickly made an indicator that indicates the center and the border of the screen, and adjusted the model. Then, I converted the model to md3 and applied it to the GZDoom. However, as you can see, I made the indicator fit directly into the player's camera. But, the posture looks obviously different from what I expected. Are there any additional settings to make those cameras really 'same'? Sorry for the unorganized and worst English.

That's just how models work I believe. They always angle towards the center IIRC.

Sorry but I don't understand. Does that mean every mesh that fills up a model angles toward the center when applied to the first person weapons?

Yep. You can see it if you adjust the offset of the model to move towards the right. It will automatically angle towards the center.

What? Sounds absurd. Where would the "center" be? 32 units from the viewpoint? 128?

Now I see it. Thanks!

And, one more question. Just like Cherno's question, I want to know the exact position of the 'center'.
