this is the way;
the shader wasnt related to this
it was the placement of brushes
when i placed my grass and caulk in z-fighting the shader will be stone or metal = no landmine
when i placing the grass without z-fighting the shader will be grass
so we’ve find a bug here:D
dont let your grass-textures z-fighting with caulk, the landmines will not work!
the reason why i thought my grass worked was becouse the grass didnt z-fight in the allies spawn, but it did in the axis, so when i tested landmines first time I spawned as allied engineer and the second time axis engineer and the allied again…
however; as I said dont let caulk and grass z-fighting…
I could probably done something like that too
