How to mass change decal color?
I've recently been experimenting with realistic-looking hair in Roblox studio and came across a grass plugin that would add grass (Landscape Brush tool). This plugin adds a custom mesh along with a decal into the workspace. The plugin worked very well; The hair was SUPER realistic. No, my problem was that I couldn't change the colour of the grass all at once. I've tried making a script(As shown below), but it doesn't seem to work. I could go in and manually change each piece, but that would be a huge waste of time, especially since there are at least a hundred.
local this = script.Parent
local grass = this:GetChildren("Grass")
local grassDecal = grass:GetChildren("Decal")
function Color()
grassDecal.Color3(170,0,0)
end
This is placed inside the model that contains both the part that needed hair along with the grass. (How do you add pictures in the forum?)

GetChildren doesn't take any arguments, it just gives you every single child
also, you can't change the properties of multiple children at once with a single assignment; you have to iterate over every single one with a for loop
local this = script.Parent -- no idea why you do this but let's just go with it
local function Color()
for _, child in pairs(this:GetChildren()) do
if child.Name == "Grass" then
child.Color = Color3.fromRGB(170, 0, 0) -- Color3.new is from a 0-1 scale, you need to use Color3.fromRGB for 0-255
for _, decal in pairs(child:GetChildren()) do
if decal:IsA("Decal") then -- if the decals are the only children of each blade of grass, then you can remove this part
decal.Color3 = Color3.fromRGB(170, 0, 0)
end
end
end
end

I guess this isn't an entire answer, but I found that I can duplicate the grass part, change the color, and then make it into a custom brush, therefore nullifying the problem.
