Hi hi! Had to pause my VFX journey but I’m back!
So, I want to make some kind of slash effect and wanted to control the motion by scrolling the texture from “outside” the mesh, like so:
The issue is some artifacts are showing up when the texture is “out”. Plus, the artifacts change in a glitchy way depending from what angle I look at the mesh.
This is the Mesh I’m using:
This is the Texture I’m using:
Edit: Wrap Mode is set to Clamp
I also experimented doing the following on the Shader:
Hi there. I’m pretty sure it’s because of the Mip-Maps, so first thing I’d do would to setting Border Mip-Maps on both textures, if that doesn’t help try disabling mip-maps just to see if that is even the problem.
If it is then this post from bgolus will have some answers Need some help with strange lines - #2 by bgolus
For this particular case, another solution would be to explicitly black out any area outside of the 0.0 - 1.0 range of the UVs in the shader. In shader graph you can use the Rectangle node to accomplish this.
