Hi All, I added some sort of breathing effect to my material, and while it works fine, the WPO cracks in small pieces. All of the tutorials I’ve watched dont have this going on. Id love to fix this 
I highlighted the issue in the attachment.
Thanks for your help!
Meet the same problem 
My material actually worked perfectly without any cracks until today.
And suddenly, many cracks appeared just now, and I’m very sure I didn’t do anything with the materials or mesh that are related to the asset.
My engine is 4.26
waiting for a solution
OMG just realized this was posted 2 years ago…
I can’t find anything about the crack bug and solution except for this post and another one about the IOS devices.
seems a dead-end rn
