    @6:43 - Can see how geonodes can be used to create some cool masks, or various effect type structures pretty quickly.

    Thanks this was pretty simple to get back in to Blendering. Atm trying to get through the most ugliest retopology of a fish I made and needed a break. This was nice I plan to play more with it beyond this but nice starting point to already have in my pocket.

    When you go into your Gumroad account, in settings there is a line which includes Payout and Payments. It is in the Payout section where you can choose PayPal. Once that is done you can go to the Payments section to enable instant payment with PayPal. I hope you have the same setup as we have in England. Best wishes, IDB.

    Excellent Tutorial. Congrats!! I’m wondering if we could export it as 3D (fbx, dae, gltf or glb) for augmented reality. Is it possible?

    • @HEYPictures-legacy
      @HEYPictures-legacy  2 роки тому +1

      That is possible if you apply the modifier "Geometry Nodes". But it does not transfer animations. So if you want to have the grass still it will work and you just have to apply it. But unfortuanetly without any movement. If you have applyed Geometry Nodes, you can go to file -> export -> fbx., dae.....

    Would using the hair feature in 3.3 be the same as the "instance" node? Would using hair be effective at making grass or would it have too many limitations?

    Hey thanks for the tutorial it works great!
    I was wondering if it is possible to create realistic Gras without realizing the instances.

    • @HEYPictures-legacy
      @HEYPictures-legacy  2 роки тому

      Thanks!
      It is possible but not even near as realistic. Then maybe you have to rotate the instances according to the noise texture but they won't bend because to gain access to the mesh data you have to realize the instances. Rotating is the only choice I guess.

  • @TheNydeon1
    @TheNydeon1 2 роки тому +1

    Hey :) I loved the tutorial, it was great ! I'll try to use it for Clint's render challenges. Quick question, how do you apply a color to the grass like in your demo ? I've tried multiple things but couldn't get it to work :/
    Edit : I was able to do it by adding a "Set Material" node just before the Group Output :)

    • @HEYPictures-legacy
      @HEYPictures-legacy  2 роки тому +2

      Thanks. Yes you have to assign the material that you want to use with the set material not and if you want to have a random color variation for every grass plate, you have ro drag a random value note out of the output node and assign it to a new attribute. Then you can use this attribute in shading. And of course, we want to have a different value for every instance and not for every point so we have to use a capture attribute node and set it to spline

      For the random color of each instance, as they are meshes it can be used the Mesh Island node that goes into the White Noise node and out of the Output.

      You can chang the speed if you use a math node set to multiply after the scene time node. If you multiply by 0.1 its slower and if you multiply by 2... its faster.

  • @MrTomyCJ
    @MrTomyCJ 2 роки тому

    What if you create a bunch of base models with different wind rotations, and the geo nodes swap between those instances per blade of grass to simulate an animation? That way you don't need to realize instances and the performance (at least memory consumption) may be way higher. I made a proof of concept and it seems possible! (~50k instances animated in real time in viewport).

    • @HEYPictures-legacy
      @HEYPictures-legacy  2 роки тому

      Good thought but in my mind it doesnt sound like it would look realistik. Doesnt it glitch if you swap?
