Deformable meshes flicker when MeshPart size changes

This bug seems to occur whenever something new is added to the player, and it still a issue that hasn’t been resolved as of May 1st 2021

Same issue here. Trying to update a decal welded and parented to the head/character, and this makes the mesh deformation parts on the character flicker

Sorry, could you clarify how to enable these fast flags? do you need a fast flag editor? or can you do it through studio?

Sorry, my mistake, there is no easy way for you to enable flags. We have a fix for the skinned MeshPart update flickering issue that we will be releasing sometime in the next few weeks.

One thing to know, even when the flickering goes away, updating skinned MeshParts like this will be somewhat expensive and may make the game laggy if it happens too much. In the future we may optimize it further, but for now you will have to keep an eye on it.

Is there any update on this fix? I am experiencing severe flickering with my skinned mesh ocean that I would very much like to ship in a game.

Here’s what the issue looks like:

I am moving around bones inside a skinned mesh, which works fine, but then there are these split frames where suddenly the bones lose all effect and the mesh plane becomes completely flat.

I haven’t actually gotten any of these issues for my own ocean. Do you update WorldPosition? I do that and receive no issues. Though it could also be because I have LoD and culling to only update a few bones, which can impact flickering.

I update worldposition, yeah. My bone count is actually quite low, and I cframe the ocean around to follow the player. Is it possible that having a 2048 stud ocean is the problem?

From my experience, there’s only a very select few properties on the MeshPart you can change without it triggering the flicker. Changing the CFrame of the parts has definitely caused it for me.

Skinned MeshParts flickering to the bind pose is a known issue that has been fixed in our internal codebase, but not released to production yet. The fix is part of a larger update that we are still working on, and we can’t release it until the entire update is stable and production ready. Rest assured this is one of our top priorities, thanks for your patience!

I’m also experiencing this bug in my upcoming game which I am developing when removing meshes, was the internal codebase released?

This is still occuring in a game I’m currently developing for, Game Link.

The repro posted above by EncodedLua still has the exact same bug happening, could you provide an update on the situation? You said that a fix would be released in future weeks back in June, has there been an issue preventing the fix?

A lot of our players encounter this issue in our game and report it to us as a bug, however we can’t find a work around for this and are also working on a new update and one of the effects in the game suffers this same issue. If an issue happened in the patch or the larger update is taking longer than expected would you be able to provide a time frame for the release so we may plan our update accordingly?

This fix is tied to a number of other unrelated changes which has delayed its release, but it is on its way soon. I can’t give you an exact eta, but you will be getting more information about the rollout in the next few weeks. Thanks again for your patience.

Heya, to clarify - will this also fix meshes flickering when changing the position offsets of their textures, or is that a whole other can of worms?

Flickering in what way? Deformation flickering to bind pose? Or texture flickering?

It seems to be the former.

In that case, yes, it should be fixed when our update goes out. If you want to test this to be sure, try to reproduce the flickering while playing the place in Studio. If you can do that, then turn on Cage Mesh Deformer Beta and the flickering should go away. If it doesn’t go away, please let us know. Thanks for your help!

Hey, activating the mesh deformer beta has caused issues in regards to texture tiling:

The texture was originally seamless, but now it is not, along with other artifacts.
The studio place with the health bars is the place with Casge Mesh Deformer Beta turned on, and the baseplate is the default.
I’ll PM you the repro part shortly https://devforum.roblox.com/t/repro-object/1494572
