How to make footprints?

Question

Unity

Good afternoon. There is a machine, how to make tire marks when braking, for example.
Please tell me the article maybe or an example on YouTube.
Thank you very much .

Answer 1

Usually this is done by the Trail system, look =)

Here is a guide using simple shadows as an example:

in the unity example

to apply tire marks, a special shader is used, a generated mesh and a programmatic change in the surface texture at the touch points (according to normals, they did without spotlights) ... the script is solid there, but you can figure it out.
I didn't like the parallax in the yunk at all. I just made a crazy hatmap for the footprints of the moon rover on the ground.. and he showed me almost flat garbage!! but if you have a fixed camera angle, then I think simple decals with a normalmap through a spotlight will be quite enough.

Answer 2

A fashionable material with a self-written shader, for example.
