This might sound dumb, but how do you add the grass sprites to a map?

Use specific textures that have them, or create your own (the info should be in the vmt). They're controlled by the "details.vbsp" file, which is in the gcf and work the same way the skybox trees do.

To find out which textures have them, you can have a look at the stock maps and see what textures are used. I don't know if someone's made a list of them yet.

How do you make them move when a player goes through them?

okay, i applied a texture i know has grass, but when i run the map, they dont show up in game.

Some graphics cards dont render the this type of grsas (prop_detail).

You have to make it a displacement.

Tip -

1. Duplicate the texture you are going to use and rename it to a new one.

2. Find the sprite texture and rename it to a new one.

3. Edit the .vmt file to point to the correct new textures. Dont forget.

4. Scale the sprite larger by about 25%.

5. You now have larger grass that covers more area with less sprites.

6. Tweak until you have a lush grass field.

That's a cool tip WT. Can be useful with large open fields.

Don't know if this will help or make clear as mud:

Also, as far as I know you have to run VIS for it to show up, I could be mistaken.
