hello, i’m trying to project materials and maps on a mesh in the element graph, i tried this to project them onto the mesh, but it does not seams to be a tri-planar because the seams are pretty visible.
how could i do it, or is it possible to do it(without going deep into the math)?
Hello @HoH,
Thanks for your post!
The Material Mesh Project node uses tri-planar projection. It looks like you might need to adjust the parameters in the Transform category for the node to match up the pattern for the different axes.
I also wanted to suggest a couple of other nodes that can use tri-planar projection, such as Mesh Project and Mesh Projected Mask. Both of these nodes have a gizmo in the viewport that make it easy to adjust the projection.
Thanks again!
i noticed it in another asset too, to solve it i sow it was needed to bring up the solidify parameter ( in the mesh project ) at .01, because it’s set at 0 at the start. i found that in a couple of cases, where i had to bring it up or where i had to add it separately because it there was not in all the nodes where it was needed.
i fixed it in a way with the solidify but then there is the visible seam also when moving the others parameters, both in the boat i was doing and here too.
other problems happens with this other map where it get distorted and here the seams are very visible.
i also sow these nodes, they should just apply a triplanar to the grunge, but it does not seam to be working well
Thanks for the additional information @HoH.
Are you able to share the spear asset for us to test with internally?
here is the file, with some comment and sign to show where the problems are in the nodes and in the mesh.
the blue comment indicate where to click for visualize the mesh with baked maps
Hello @HoH,
Thanks for the file with the comments and painted arrows.
After looking further at your file, it appears that the texturing around the UV seams can be improved by adding Solidify nodes to both of these Mesh Mask Builder nodes. For the Solidify nodes, a mask can be created with a Mesh Mask node and provided as a mask input by enabling the “Use Mask” parameter.
It’s worth noting that the blur effect from the Mesh Mask Builder can cause seams. This is a current limitation, but in a future release, a more advanced blur option will be available.
Thanks!
