Attempting to re-add old roblox textures

Help and Feedback Scripting Support

#1

In short, im attempting to replicate the old roblox textures. I’m using a script to load these textures, and it works fine.

The problem is that I have no idea how to do things such as stopping visual fracturing between parts, making parts not be extremely shiny or textures being stuck to a single colour (ex: Grass is always Green, so setting it to white wont make it white, only a very white green). Yet, it seems people like Clonetrooper or the people behind RetroRoblox managed to do it.

I would like help with trying to make these textures work by directly importing them from old roblox clients and making it work as intended. If anyone has experience doing this, I would gladly appreciate your help.

Script in question, put it in a localscript inside ReplicatedFirst.

-- EXAMPLE TABLE --

-- 	local MaterialTable = {
-- 		{TextureID, Transparency, U, V, Enum.NormalId.Front},
-- 		{TextureID, Transparency, U, V, Enum.NormalId.Back},
-- 		{TextureID, Transparency, U, V, Enum.NormalId.Top},
-- 		{TextureID, Transparency, U, V, Enum.NormalId.Bottom},
-- 		{TextureID, Transparency, U, V, Enum.NormalId.Left},
-- 		{TextureID, Transparency, U, V, Enum.NormalId.Right}
-- 	}

This might not be script thing and more of a GFX / texture thing, but I dont know, sorry in advance if it doesnt belong here.
