I know triplanar is XYZ-axis projected which is basically using vertex normal I guess, but I cant really its realtionship between 45 degrees angle because it's more visible at 45 angle degrees?
Hi there. I would recommend to work with 1/8 of the mesh. 1. Start with your basic shapes 2. Create seperate mesh that would act as boolean 3. Boolean 4. Rotate the mesh 45 degrees 5. delete 1/8 of the mesh 6. Clean up 7. Rotate back -45 degrees 8. Symmetri and voila. HERE IS THE 1/8th of the mesh cleaned
does it happen at a lower octave count when the mesh is less dense? does it happen at not 45 degree rotation? I've seen this sort of artefacting before but the exact cause escapes me for the moment
45 for for skinning is pretty optimal. If 0 is arms at the side and 90 is T-Pose then 45 is right in the middle. The shoulders need all the help they can get. It makes modeling a bit wonky so I normally suggest model in T, and before unwrapping pose them at 45.
