[Help] Triplanar Projection create lines, NOT UV seams, any ideas?
Hey all, Scratching my head over this and hoping peeps can help. I am projecting a Perlin Noise texture to a cup. If I use a triplanar projection these odd lines and artifacts appear that are clearly inline with the wireframe (see images 1 & 2). The same texture using UV projection works fine (see image 3). In fact,… -

Ok, with your mesh I was able to get the lines show with a tri planar projected perlin noise too. It might be because of the mesh being low resolution, as you said, but I really don't know 🙃 Maybe someone else does. Whenever I use projected noise, it's typically small scale, so it's not that apparent. Well, I hope you find… -

Made a very quick mock up. Here's how to repro the issue; it happens with or without baking. Start new project with cup_low.fbx Create a Fill layer, set to affect height only, set height to -0.2 Add black mask to layer. Add fill to mask, set to 3D Perlin noise. The lines are, for me, present, and become more so if the… -

Hey! Do you tri planar project "3D Perlin Noise"? It's not clear to me from reading the posts :P If you do, I doubt it's indented like that, since the generated noise texture is based on the baked position map. I would just tri planar project regular "Perlin Noise". -

I think it's behaving correctly The result is intrinsically tied to the shape of the object you feed it so as you suggest you need more geometry or a position map baked from an asset with more geometry -

It happens with both methods, regardless. I think this just an issue, since it does actually happen on the sample projects - this image is from the MeetMat body, at the hip. I think it's just far less noticeable because the geometry is at a higher division. I think my cup just needs more geometry, if I want the camera that… -

Interesting, could you share a mesh to test this with (or screenshot of layer/mask/noise)? Can't reproduce this in PreviewSphere sample project.
