Oh, is that Blender? I get it. It's a bit off-topic...
But I can ask - could you explain Blender, which I've started learning a bit...?
I didn't have this question in 3ds Max, I don't know why. I used 3ds Max for a different series of games, and everything worked fine. But now, in Blender, I have this question: "Shade Smooth," as someone suggested on another site (but that's all they said). Is it just a visual effect? Does the model not actually become smooth?
Here's my question, or rather, a series of related questions, if you can, please explain! -
What is "Shade Smooth" for? How do I properly prepare a model for export to a game so that it is smooth and has a good appearance? In 3ds Max, I did two things for the model: "Auto Smooth" with a value of 45 (is "Shade Auto Smooth" in Blender the equivalent?), and I used the "Edit Normals" modifier to bring the normals "to a normal state." That is, the polygons... I don't know how to explain it, but the model simply acquired a normal appearance and looked smooth in the game and generally looked correct.
Well, with "Shade Smooth," the model is smoothed automatically (when exporting to the game, the smoothing remains).
With "Shade Flat," it remains as it is, angular.
In principle, "Auto Smooth" can also be adjusted. You need to select "Shade Smooth," then "Edge Split," and then adjust the desired smoothing angle.



Or, in manual mode, mark the edges that need to be sharpened.
