White artifacts on texture

Whole texture is 5120x5120
When imported, texture is not clear and theres white pixels that appear on the texture despite there being none on the original texture.

Tried repainting and nothing has changed.
Any solutions?


What even is that supposed to be? Arms?

Anyways, the issue is probably due to fault UV mapping. Basically some parts of the UV map do not engulf the color properly. Ensure they do.

I dont think so. I’ve checked the UV map and its all good. One suggestion I got was to decrease the entirety of the map to 1020 by 1020 because apparently it’s a compression issue. I’m going to try this and see if it works.

  1. MAX texture size is 1024x1024. Any bigger compresses down.
  2. Maybe, there’s transparent pixels, with white color. They have tendency to bleed. Color them too, so they will be still transparent, but have for example purple color.

I just compressed and made sure there werent any bleeding pixels… and it looks even worse.

Here’s the whole map compressed if anyone want’s to take a look. The bleeding edges are outside the map.

May I ask - does this character has Humanoid under it?

No… Now that I think about it I totally forgot to add one… Will do later and will update you.

In this case, I honestly don’t know why that occurs. My assumption was that Humanoid downscaled texture to 420x420 size, but if that’s not the case, then IDK. Your texture is 100% good, and shouldn’t have such artifacts.

I actually cant add a humanoid because apparently the game this is for dont use humanoids.

Im trying to think… The UV MAP looks fine, the texture obvs has no issues and I’m using surface apperance to apply. Could it be a bug?

Hm…
Can you try to do this:

  1. Put this texture to MeshTextureId
  2. Put this as Decal on flat surface
  3. Put this into ImageLabel with 1020 px size

Cuz if it’s bug, then on this 3 situations it should behave correctly. Otherwise, it’s either Entire Roblox image related issue, or image issue itself.

could’ve made it more obvious

Option 1 appears to have white border bleeds
Option 2 is still showing pixel corruption
Option 3 Actually appears to be fine.

Still cant get the texture to look clean. Out of ideas.

Chroma subsampling.

I find it particularly noticeable on this Roblox billboard

The only solutions i can think of are to make a higher resolution texture, or reorganize your texture to have each island be larger

Hopefully someday roblox will chill out a little bit with the texture compression in game, it’s very extreme as it is now

I’ve noticed that the higher the resolution, the more likely pixel corruption will occur. I will try to reorganize the islands and I will see what will happen.

I’ll let you guys know if this solution worked or not. Have to leave for today.
