Materials that use a value `$surfaceprop gravel` make the marine movement slow and clunky, which feels bad especially when player plays on a server and has 70+ ping. This happens because **gravel** surface is set to have `"friction" "0.4"` instead of standard `0.8` in `reactivedrop/scripts/surfaceproperties.txt` As I remember this was an issue in `rd-area9800PP2` map ending but was fixed at some point. Now this is an issue in maps that use `blend_grass_gravel_01_lowdensity.vmt` and similar materials. Specifically the **Dark Carnival** campaign on workshop and the upcoming **Swamp Fever** campaign workshop port. `blend_grass_gravel_01_lowdensity.vmt`, and similar materials, are shipped with RD so we can either change them to not use `$surfaceprop gravel` or we can change gravel to have standard friction `0.8`. I'm suggesting the 2nd option. Note: see the comment of original Alien Swarm developers in `surfaceproperties.txt` 😺: ``` // asw no sliding, feels horrible // "friction" "0.35" ```
