There are several ways. In general there are two parts to it. First there's the actual snow layer which could be just an actual mesh on top of the road. To clear the snow layer you could use a masking texture which you essentially "paint on" / clear with an alpha value of 0 so the snow layer is hidden where you drove. Painting on textures can be quite expensive especially on mobile. Though the painting doesn't need to do every frame. Since the actual edge is hidden below those "snow chunks".
This is already the second part, spawning in those chunks of snow. In the video it looks like they are actual 2d sprites. There are several points where you can actually see the edge of the snow layer because the snow chunk sprites do not properly hide the edge (for example around 0:17 at the straight part).
Instead of using a mask texture one can also dynamically create a mesh with the desired cut-out shape. Both approaches aren't that difficult but require some knowledge about texture manipulation, shader programming and mesh generation.
Hello, thanks for answer, if you have discord can you add me? I have a couple more question about this, here is my discord ID davidsedrakyan#6861
I have discord, but no i will not add anyone for several reasons. First of all I use discord only sparingly with my close friends. Second the main point of UnityAnswers is to provide public information for everyone. Private conversations bypass the community. And finally if those "couple more questions" are actually about implementing such snow in code this will quickly turn into a "please write my code for me" thing. If you have a concrete question, just ask a seperate question, though it should be more detailed and specific than this one. However before asking you should search if something similar hasn't been asked already
