Hi,

The resolution of 3D depending your computer especially your graphique card,

But you can control your 3D options and if not the case switch Anti-Aliasing to max

the point to also take into account is the size of your image file, ideally at least 400×400 pixels, without exceeding 900×900 pixels, of course it can also be with a different ratio for example 1200×600 pixels.

After that, don’t forget to define the width of the application, which gives a better rendering of the textures. In the example below, 560mm for 560 pixels is not true in real life, but it gives a good approximation without calculation.

Hope that’s helpful, Alex
