How to highlight every avatar in Roblox with Bloxstrap

If you mean making every character/avatar in a Roblox experience visible with a highlight effect , that is usually done with Roblox’s built-in Highlight instance, not by “highlighting” through Bloxstrap itself. Bloxstrap is a launcher/bootstrapper, while the actual highlight behavior comes from Roblox scripting and engine features.

What works

You can add a Highlight to each character when they spawn. A common approach is to parent a Highlight to the character model in CharacterAdded, which makes the effect follow that avatar.

Example pattern:

lua

local Players = game:GetService("Players")

Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		local highlight = Instance.new("Highlight")
		highlight.FillTransparency = 1
		highlight.OutlineTransparency = 0
		highlight.Parent = character
	end)
end)

That setup highlights each player’s avatar as it appears in-game.

If you want “every avatar”

There are two common interpretations:

  • All players in the server: loop through Players, then add a highlight on each CharacterAdded.
  • All character models already in Workspace: scan existing models and attach a Highlight to each valid avatar model. Roblox highlights can be applied to models and characters.

Bloxstrap angle

Recent Roblox discussion around Bloxstrap has focused on whether Roblox changes affect it, but the launcher itself is not the thing that creates avatar highlights. The highlight effect is a Roblox Studio / scripting feature.

Practical note

Roblox highlight usage has limits and performance considerations, and community documentation notes a cap on rendered highlights. If you are trying to highlight everyone at once in a busy server, keep that in mind.

TL;DR

Use a Roblox Highlight script on each avatar; Bloxstrap is not required for that. If your goal is cosmetic highlighting in your own experience, the cleanest route is to attach highlights on character spawn.
