Editable meshes not casting shadows

[dae_vinity (daemon)]

1. What do you want to achieve?
   Shadows on editable meshes.

2. What is the issue?
   They don’t cast shadows.

3. What solutions have you tried so far?
   Checking the CastShadow property plenty of times
   Different mesh loading options
   and many more i can’t remember

Are you able to recreate this with just a single part? Like try to make a single beveled part using the same code in a separate place and see if the problem persists. If it does, send us (or me personally if you’d rather keep it private) that separate place and I’ll try to look at it. Based on the description, I don’t really know what else to recommend at the moment.

Bevels.lua (2.9 KB)
bevel.obj (5.5 KB)

put the lua script in ReplicatedFirst
a meshpart with that obj file should be put in ReplicatedStorage.Assets.Bevels. it uses it as a base.

if my code is god awful i apologize lol, first time doing editable mesh stuff ever

Alright.. I’m striving more toward this somehow being a roblox bug, since even this super simple example fails to produce shadows

local AssetService = game:GetService("AssetService")

local meshpart = workspace:WaitForChild("MeshPart")

local mesh = AssetService:CreateEditableMeshAsync(meshpart.MeshContent)

local newMeshPart = AssetService:CreateMeshPartAsync(Content.fromObject(mesh))
newMeshPart.Anchored = true
newMeshPart.Parent = workspace

Don’t see any bug reports on this yet tho. I think I’ll look into it a bit more and if I don’t find an answer for it, I’ll make a report.

Here’s the bug report if you’re interested.

Meshparts created from EditableMeshes don't have shadows

Oddly enough, it seems that if you create an EditableMesh from a MeshPart and then create a new MeshPart from that EditableMesh, the new MeshPart will not cast a shadow, even though CastShadow is turned on. This simple code block demonstrates this: local AssetService = game:GetService("AssetService") local meshpart = workspace:WaitForChild("MeshPart") local mesh = AssetService:CreateEditableMeshAsync(meshpart.MeshContent) local newMeshPart = AssetService:CreateMeshPartAsync(Content.fromObjec…

As far as I can tell right now, your best bet will be to run the mesh generation code in studio (i.e not in run mode), and if it still doesn’t have shadows, then publish the meshes using AssetService, in which case they should have shadows again.
Tho be careful not to ruin your map, since running things directly in studio can permanently delete stuff, even though Ctrl+Z usually still works.
