Hello, I 'm sorry to bother you but for this specific part I don't get how you had a result without connecting the nodes and on my part I don't have the results until I connect the nodes like you do at 6:06 min. Thanks you.
Hey, not a problem! Looking at the timestamp I'm assuming you mean you're having problems viewing the profile curve I create? Make sure you're viewing it with a viewer node, which comes up when you press Control-Shift Left Click. If this doesn't solve your issue please do explain exactly which bit you're struggling with and I'll be happy to help!
Thanks you for you response. For more context I added screenshot, where you can see you can work on the sidewalks with the viewer on and in other hand I can't but I have the same nodes you have. I don't know if its a problem of viewing or a parameter but not viewing what I do before hands its a little inconvenient. Thanks you.
Thanks you I tested it out and it wasnt working even at 100 meters but after that I tested it out with your file and I have the same problem. I think its my blender config the problem.
