Still totally valid and the node is just split into 3 separate sample nodes to make it easier to maintain 👍

I learned by just guessing until I started to see patterns. Don’t get dissuaded by not knowing all the maths now - it will start clicking. I learned it all practically with Blender

All games and tv work I’ve done have used Y- as forwards for models. I guess as long as your work is consistent that’s all that really matters. I assume the reason is that you want to model the front while looking forward so you need the model to be facing towards you for that to be convenient

It’s definitely hard work to learn this stuff but very worth it!

You can also use the scene time node’s “seconds” output which is frame rate agnostic. Delta time is useful as it’s just the time step since the last frame so good for scaling forces by

They have even more products now! Definitely worth checking out if you’re at all interested in animation

Yeah it’s been so long! I need to carve out some time for a new video

Haha thank you so much!

Thanks so much! What I would do is capture the selection attribute before flattening the regions. That way you have it essentially fixed in a point in time. You can use this captured attribute after they’re flattened

Thanks so much! I hope it does what you need

Oh your issue is actually the opposite. The open end points have the correct scale and the rotated one have the smaller scale. I guess actually it’s more correct to say that the profile is correct in the corners but its rotation means the wall itself is too thin. Anyway the solution is to create a node group that lets you find the angle at each point. Best way is to use two sample curve nodes, one sampling at length-epsilon and the other at length+epsilon. Then you can find the accurate tangent before and after by doing the position of the point (position node) subtract the sampled position, and sampled subtract position for the other one so the direction is consistent. Then you can do the dot product of the normalised tangents and the arccosine of that to get the corner angle. It’s hard to get the scale fixed for 3D curves but for 2D you can use that angle with some trig to find what you need to scale the corners by. For example if it was a 90 degree corner then you would need to scale it by 1/sin(45) to get the 1.41 to scale it by

@@Erindale you are absolutly right. If i convert it to mesh and scale the corner on x and y it's exactly 1.41. Only issue, I have absolutly no clue how to set this up in geo nodes 😮‍💨 could you maybe... Short content... Tutorial? Or Download 😅 🙏 this stuff drives me crazy for 5 days straight now 🙈

@dertobbe1176 I’ll try and throw something together soon! But ask on my discord help channel. This kind of thing comes up every now and then so you might find a nodegroup made for it

What is it you want the mirrored curve to be doing? How do you want to the final mesh to look?

@@Erindale For example half of the skateboard, longitudinal direction. With one spline you can also make both ends upwards and with the top view you can make a shape. puu.sh/KgCnO.jpg

@TynkaTopi to loft a skateboard shape it would be easier to imagine it like taking a skate deck and cutting through it with a saw lots of time. The slices that you’d see are the profiles and the line down the centre of the board would be the path. Then you can loft those profiles along the path to get the shape again

@@Erindale Yes, I'll try that way. With that method, you can do it accurately even if the board is concave in the middle.

Modulo returns the remainder of a division. For example if we modulo The range 0..5 by 3 we’d get: 0/3=0, 1/3=0 remainder 1, 2/3=0 remainder 2, 3/3=1 with 0 remainder, 4/3=1 with 1 remainder, and 5/3=1 with 2 remainder. So in this case we’d see 0,1,2,0,1,2. Extending that to 40 modulo by 20, we’d expect indices 0..39 to become 0..19,0..19. These values then correspond to the indices of the spiral curve

@@Erindale ohhhh I got it that was so simple. So like it repeat itselfs after 19 and starts from 0 again right? I got it thank you.

@occasionallyhuman yeah the easiest way to think of it is that modulo is a function that takes a gradient and breaks it down into smaller gradients. If you modulo by 5 you’ll get gradients 0..4, by 20 you’ll get 0..19

Thanks so much! There’s really no limit to Blender

I’m glad it helped!

Yes it’s on there!
