I think I’ve seen this happen before when someone had turned off anisotropic filtering in their GPU driver.
Let me just paste what I sent them:
The problem is that “anisotropic filtering” is not being applied for your model texture. VTube Studio automatically uses anisotropic filtering, but it doesn’t use it on your PC for some reason. The only reason I can think of is that you disabled it manually for some reason. This can usually be done in the GPU driver. I don’t know what kind of GPU you have, but please make sure anisotropic filtering is set to either “application controlled” or “8x” or “16x”.
Here’s an example of how to do this for different GPU drivers: Glossary:Anisotropic filtering (AF) - PCGamingWiki PCGW - bugs, fixes, crashes, mods, guides and improvements for every PC game For NVIDIA GPUs,
this can be done in the “NVIDIA Control Panel”. Make sure it’s NOT set to “Off”.
Thank you for your message.
Unfortunately there was no ANISOTROPIC item.
I tried turning on the items that were turned off, but that did not solve the problem.
I am wondering if it is a bug in VTS or a specification, since the problem occurs with clipping of some layers that are too large in area.
Thanks for your message.
We did not solve the problem because it is not a problem caused by resolution or other issues.
It is probably a bug or specification on the VTS side, so there is nothing we can do about it.
