An asset was bought in the unreal market, it is a weather creator, it contains a snow storm button which must be duplicated to make a sand storm, I contacted the developer who told me how to do it. I was able to get the duplication but I could not place or rather make a parameter the color of the terrain snow to be able to change it to the color of sand. I have no knowledge of materials to achieve that. That's why I need a person who

1 get to make a terrain snow color parameter.
2 get to make a color parameter of the fog.

The creator told me that in the snow material, I have to enter the BASE COLOR as a parameter but I can't, I don't know how to do that.

SOMEONE WITH KNOWLEDGE OF MATERIALS WOULD EASILY BE ABLE TO DO THIS.

IF YOU WANT MORE INFORMATION, URGENTLY LET ME KNOW THANKS.
