It's really a great tuto, easy to follow and everything works. It's a bit resource-intensive, so be careful if you have an old PC like me. Thanks a lot.
This is amazing. legitimate question as a a person who wasn't able to attend school for my passion- How would anyone ever understand how to do this without a guide? Like what is the logic behind using a math node to multiply a musgrave texture by the spline parameter to prevent the bottom of the grass from moving?
after a while I started to figure out how all the nodes interact with each other and what they do so thats how I can make these things myself. As for the logic behind the multiply, the spline parameter is a 0 to 1 value from the beginning of the curve to the end in a gradient. So when you multiply that with the musgrave texture (that moves the curve) you end up with 0*musgrave=0 at the bottom and 1*musgrave=musgrave at the top. So essentially you just remove the musgrave at the bottom and then inbetween there is a gradient. Hope that makes sense!
Is there a way to improve performance on a large environment with your grass technique (without reducing curve count or resolution)? Would Proxies help? I always end up giving up on using geometry nodes because of performance issues. 😟
did the musgrave node get renamed because i am searching it to find nothing and i see a forum saying it was changed to noise texture but the node looks entirely different
I have a pre-made grass models, i scattered them all over the plane, but when zoomed out it looks very monotone. Is there a way to make them change hue with a noise texture somehow?
I dont really use gscatter but i think they already use geometry nodes right? If not its better to use the gscatter assets in geometry nodes because thats generally more optimized and adjustable
Hey man, great video. works great. But I ran into a small issue. when adding the spline parameter the upper vertice becomes static instead of the bottom one. any idea how to fix it?
Hey man! awesome tutorial, really cool to see what you did ^^ there was one small issue I ran into which I couldnt figure out how to fix or what it was, basically after applying the texture, it applies it on each grass blade seperately rather than following the texture of the plane or something, I dont know quite how to explain, however it results in the grass having some really nasty looking dark spots based on the voronoi texture and dont follow the plane texture smoothly, making it look kind of weird, do you have any idea what I could do to fix it?
hey thank you for the quick response ^^ unfortunately that did not fix the issue, it gave a very weird result that is even weirder than what it was before🤔 I tried by fully replicating the node trees of the video but it somehow resulted in the same thing happening which is very odd to me (sorry to bother btw 😓)
@@autismboyrdf8486 Its a little hard to troubleshoot over yt comments but i think you might have to apply the scaling! press ctrl + a and select all transforms to apply the transformations and that might work. I watched the video and i did change it to object so you should probably also use that in combination with applying all the transforms. I hope that helped!
copy paste of a previous response: it's a part of the style, it's unlit. If you want to have lighting you will have to replace the emission node with a principled bsdf but it will not look as good
@@baeac I was about to edit that I found a way that looks good- and with keeping the emission! good tutorial nonetheless, perfect for what I was looking for
since i added the avoid node my grass wont move and now i deleted it and still doesnt work i guess i ahev to start from the beginning and ignore that part....
i used a grid instead of a plane for more control, but now i don't know how i can use the delete points node , can anyone with the know how kindly assist.
I have wo quesitions: firstly, when I add the delete geometry node, all of the grass just disappears and even following the steps later on in the tutorial this doesn't get fixed. is there a solution? secondly, is there a way to fix the grass not waving?
Hey man, i had the same issue and this is what fixed it for me. Im not sure if you solved it yet but i noticed on the right panel with all the icons, if you click the modifier icon (the blue wrench), and where it says "collection", you wanna make sure you have your "avoid" collection selected
Help please. I did everything like in the video but my grass just won't move. The first seed graph is purple like in the video but I don't see anything moving.
Hello, I'm not good in English but try to explain what it's my problem, in the minute 6:54 aprox you explain about the collection and add a collection info to the group input and go to the modifier and you can add your collection avoid, but I don't know why I can't see in my modifier the option to add a collection... Please, help me🙂💔🤧
Hi, I don't know English well either. But I found a way to deal with your problem. Just leave Collection Info unbound to Grup input. Put the collection of the object in the Collection Info itself.
it's a part of the style, it's unlit. If you want to have lighting you will have to replace the emission node with a principled bsdf but it will not look as good
but what next? for example, I created a location and I want to add grass to certain areas of the area, say in the corners of buildings, a little in a vacant lot, what if I want the grass to be somewhere higher, somewhere lower. How can I use this method? How many computer resources does this method consume? But what if there are also animating flags and water in my location? Is this method optimal or is it just a way to create grass without the ability to use it later?
