I was looking for copper and found gold. Amazing setup, big thanks for sharing.

[@sistemafuturo]

Thanks for sharing, cool and already refined technique!

[@sistemafuturo]

Actually, projects like this one make me think of blender as an interactive tool, for example UPBGE now can do so much more with such minimal tools...

[@seranca1]

Excelent work!! Is there a way to create a shader to make the LIDAR points the same color as the object its touching? Intead of color based on the range, color based on the neareast object material Or any way to segment the LIDAR ? I'm still new to blender

[@emilsvfx]

yes it possible but need make adjustments for this data transfering from mesh to points

[@seranca1]

@@emilsvfx Would you be able to help me?. I'm not able to find any similar solution online

[@emilsvfx]

@@seranca1 probably not. But search tutorials about data transfering inside geonodes

[@martinblaszczyk1071]

I see you can change the Epsilon to change the FoV, but how do I change the FoV to be exactly 90 deg, or 45 deg?

[@emilsvfx]

you can make your own logic how to delete mesh, for example try to use gradient node and then compare it

[@martinblaszczyk1071]

Thank you. I'm new to blender but I'll give it a try@@emilsvfx

[@muneebkhaki]

hey! can anyone please tell me what is that not equal node before delete geometry ?

[@emilsvfx]

boolen node what gives value 0 or 1

[@muneebkhaki]

@@emilsvfx thanks

[@maxi74x1]

What blender version is this? Answer 3.1 How do you get "Not equal" Its a compare node " Question, why is it that mine does not work? copied everything and it still don't work, I have a tiny sphere inside of the empty. but nothing happens

[@emilsvfx]

I don't know 3.1 or somthing

[@maxi74x1]

@@emilsvfx another question, with the instagram thing at the start, is it the same as this or is it different? if it is different can I get a link to it, it seems that this tutorial doesn't work. no matter how hard I try.

[@emilsvfx]

@@maxi74x1 Sorry don't understand you. Tutorial is the same. In you need you can but asset and recheck have it made.

[@maxi74x1]

@@emilsvfx i found the problem but not the solution. everything goes fine until i connect the "set position" node into the group output, then it turns into what is show at the mest to points node, but only 1 at the origin, not sure if its all of them or not. I hope you can help me and clarify what I did wrong. in case other people have this problem

[@zdzczx7660]

got it on gumroad, a bit upset that I can't see the actual geometry node tree.

[@emilsvfx]

Hi.Open geometry node view to see node tree.

[@zdzczx7660]

thanks, the geometry nodes tab is empty, even when I select the right object in the panel. Anyway I got it to work for my application. Thanks@@emilsvfx

[@emilsvfx]

But you select object who contains geometry node modifire?

[@zdzczx7660]

yep, selected the object with the geo nodes. @@emilsvfx

[@PhillMcraken]

Bought it on gumroad, but 3.1 has all of the Nodes showing as Undefined :(

[@emilsvfx]

Hi strange for me work fine i.imgur.com/MPxotnd.png maybe blend file opens in different blender version ?

[@Mw_kwak]

Thank you for sharing this. I've been looking for the past week how to do this effect and struggled. I'm not smart enough to figure it out haha.

[@emilsvfx]

:) if you need this asset on gumrode link you can find this asset and i update it add extra stuff for easy use

[@amasun13]

Wonderful

[@afrikaniz3d]

@Spatial Munchies haha ew, maar dankie 🇿🇦

[@sebastianpreue5270]

Hej hej, amazing work. I just bought it on your gumroad. But I found that in the file there it is no way to play with the segments and rings, like you do it in the tutorial. Or did I miss something?

[@emilsvfx]

tnx for informing me. strange, today will update it gumrode file. This setup was from this video kzbin.info/www/bejne/hmqvcnqZe7CVqM0 but i update geo node for tutorial

[@sebastianpreue5270]

@@emilsvfx Great, thanks!!! And do you know if it's possible to not just use an object but the entire collection as a target geometry. So it's not necessary to join several objets to one. I just changed the "object info" for the "collection info", but it did not work.

[@emilsvfx]

@@sebastianpreue5270 it`s possible but you need update the node setup

[@emilsvfx]

You can check gumrode i update it and add collection possibility

[@sebastianpreue5270]

Wow, your are the best thing on the internet today! I saw you changed quite a few things and it works perfectly fine. 🌟 The geo nodes are a true masterpiece now !!!
