Problem with Flat shading

Hi! I use node Material in my project. I have a problem with models rendering. Its looks like flat shading is true. How i can smooth polygons? Screenshot_10

Also kinda looks like self shadowing with a low resolution shadow texture map. Probably not but maybe.


@Arkadiy_Vinkovskiy you need to add more detail to your posts. A screenshot is not enough to tell what’s going on here. Always include the code that’s causing your issue as well, and if you’re using models, include those too. Even better, make a working example using codepen.
