    Tip with splitting the vectors and then rebuilding them to isolate one of the vector axises (axese? no idea how to spell that). You can achieve that with a single Vector Math node - use a Vector Math Multiply against a vector with 1 in all the axises(sp) you want to keep, and a 0 in all the ones you want to ditch.

      ​@@ArtisansofVaul I'm slowly refreshing myself on Vector math because it's so useful in CGI, but it's been nearly 25 years and I can't say I understood it much the first time around :D I'm targeting Refraction and Projection next to understand what in the blazes they are and what they're used for.

    Hi. So you're amazing. Had no idea I'd actually been following your tutorials for a while. Came here for the horns. Stayed for the towers. Bless. JDF, the one who portrayed the Green Ranger has recently passed away and I was wondering if there's any possible way you could do a tutorial regarding making helmets? Even if not, big fan. I regret not subscribing to you sooner.

    • @ArtisansofVaul
      @ArtisansofVaul  2 роки тому

      A video on making helmets could be done for sure. The only things that's tricky is there are so many types of helmet styles each one needs a potentially different approach. I'll have a think about a way to approach something and find a relatively general helmet to us that would work for a tutorial.

    Hey! What if my bounding box is bigger than the actual object? Can i change the size of the bounding box without affecting the geometry?

    Maybe you can help as i cant figure something out, i thought this vid might help but its not what i need
    I have a mesh to points set to faces and an instance to points node the input geometry is a plane of faces not all the same size(different size faces)
    What i want is for the instances that are placed with the instance to points node to scale the x and y to fit to each face the point is on/from
    Any ideas?

    • @ArtisansofVaul
      @ArtisansofVaul  2 роки тому

      Hmm... that's a cool idea. I'm not totally sure. At the moment I'm thinking something using either a proximity node (though I don't know if that will work for a single point) or something like a raycast node from the point to select the face as a target (though this last one seems a very inelegant solution and I don't know if it would work). This actually seems pretty tricky as a Geometry Nodes beginner. I'll have a think but if you find an answer/idea please do let me know.

    • @ArtisansofVaul
      @ArtisansofVaul  2 роки тому

      So Ive been having a look into it and the answer is "not easily" from what I can find. If you just have all the faces being exactly square its probably possible using the "face area" node as you can just square root it to get the size of the face. Otherwise it gets a lot more tricky.

    • @ArtisansofVaul
      @ArtisansofVaul  2 роки тому

      Ive got to the point I can do it for a single face by itself. Just not when there are multiple faces in an object.

      Not sure if that helps with whatever the issues you've been having with it? Otherwise you could use some other free software such as GIMP but that would probably be less simple to do.
