Күн бұрынDid you ever wonder how you can make really superior Gras/Wind Animation or Simulations really performant in Blender? In this video, I will show you a way of creating such Wind striping through a field full of grass, created fully in Geometry Nodes.

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 Жыл бұрын
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.

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 Жыл бұрын
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.....

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 Жыл бұрын
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
@anicapalini Жыл бұрын
@@HEYPictures-legacy First of all Thanks for the tuto, always interesting and something to learn. 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.

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.

When I add a material to the grass blades, it takes the FPS of the animation waaaayyyy down. Is there a way to fix this?
@MrTomyCJ Жыл бұрын
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 Жыл бұрын
Good thought but in my mind it doesnt sound like it would look realistik. Doesnt it glitch if you swap?

is there a way to use a ready made grass model and use it as an instance for the curve, instead of creating grass from the curve?

Its not so easy since we dont have a displace on curve node. It is also way to heavy to compute

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.
