How do I change the transparency of all children in a model all at once, instead of one by one?

For some reason, it fades the transparency 1 by 1 to 0. I want it to be all at once, but I don’t know what I’m doing wrong.

What it looks like: https://gyazo.com/3422da92089a4e5f4b5c8b87c6510afb

for _,v in pairs(Mystand:GetDescendants()) do
if v:IsA(“BasePart”) then
for f = 1,0,-0.5 do
wait()
v.Transparency = f
end
end
end

You should just swap the two and it would work correctly:

local MyStand = ...
for f=1,0,-0.5 do
  for i,v in pairs(MyStand:GetDescendants()) do
    if v:IsA('BasePart') then
      v.Transparency = f
    end
  end
  wait()
end

Hm, I’ve noticed that looping transparency can be laggy sometimes. Is it possible to tween the transparency? I already have the tween arguments set up, but how do I get the whole model as one variable?

#4 
local TweenService = game:GetService("TweenService")
local TweenInfo = TweenInfo.new(1) -- Time to tween
local MyStand = ...

for i,v in pairs(MyStand:GetDescendants()) do
  if v:IsA('BasePart') then
      TweenService:Create(v, TweenInfo, {Transparency = 1})
  end
end

@Legoracer didnt play the tween

TweenService:Create(v, TweenInfo, {Transparency = 1}):Play()

And no you cant Tween a model at once but if you do the for loop it actually wouldnt be noticable.

Thanks for noticing that, I type most stuff in forum editor so its hard to see everything. :slight_smile:

Wrapping it in a Spawn function should work fine

for _,v in pairs(Mystand:GetDescendants()) do
if v:IsA(“BasePart”) then
spawn(function()
for f = 1,0,-0.5 do
wait()
v.Transparency = f
end
end)
end
end

Using coroutine.create() is better than spawn because like @Kullaske said

spawn is delayed.

It works fine, but how do I ignore the HumanoidRootPart? I want it to be invisible at all times.

#10

I would suggest you using a function for the fading part

#11

I already have the transparency tween working fine and smoothly, I just need to know how to ignore the HumanoidRootPart to stay invisible at all times.

#12

Name the part the same thing and check if their names is that name

#13

Yeah but if I do that, then that’d mean I would have to rename the limbs too and that would break the whole dummy

#15

HumanoidRootPart is normally marked as a PrimaryPart or the RootPart property of the Humanoid.

You can also just iterate and ignore invisible parts since HumanoidRootPart is already transparent.

#16

It doesn’t work, the transparency is still at 0.

#17

I’m not sure how to ignore invisible parts, how would I go about it?

#18

Ignore it when tweening transparency to 0. To ignore invisible parts you just check if part.Transparency == 1

#19

So like this?:

if v:IsA(‘BasePart’) or v:IsA(‘Decal’) and v.Transparency == 1 then

#20

Why the and? Now you are only using invisible parts.

#21

Oh I thought you said to check if part.Transparency == 1, so just put an and there. I’m not sure what else to do.
