Hi, assuming that someone was enrolled in the SLIM early access program and had ImprovedModelLod enabled in that early-access, this might happen for some models with respect to StreamingMesh.
A quick fix should be something along the lines of:
local s = {}
for _, d in ipairs(workspace:GetDescendants()) do
if d.ClassName == "Model" and d.LevelOfDetail == Enum.ModelLevelOfDetail.StreamingMesh then
table.insert(s, d)
d.LevelOfDetail = Enum.ModelLevelOfDetail.Disabled
end
end
task.delay(5, function()
for _, m in ipairs(s) do
if m and m.Parent then
m.LevelOfDetail = Enum.ModelLevelOfDetail.StreamingMesh
end
end
end)
and then save the experience to Roblox.
If that doesn’t work, just in case please make sure in the early access that ImprovedModelLoD has been disabled for the same experience so there is no weird inconsistent state.
In the worst case, you may have to temporarily disable streaming (though we are actively working on a fix).
Please let us know if that doesn’t fix the issue, we apologize for the inconvenience.
EDIT: Added more context to Early Access Program
