Directly feeding in multiple lines into the Hda would require some rethinking of it, right now it would cause trouble in the first Loop where the "skin" of the wall is created. The quickest solution IMHO is to merge the input curves and feed those in a For Loop by primitive (so for each curve) and throw the Hda inside the Loop. BUT first you need to modify the first resample node of the had to be based on Lenght and not Number of Segments, so it will be equal for each curve, no matter the length

For the bricks you could use some loop with a 6 plane uv (but it would involve some orienting stuff with the curved ones), for the grout I would go with a procedural texture.

I guess it depends on how the curve are drawn in Illustrator. How do you import the curve into Houdini?

@@ezpepz i save as SVG , then i bring it to blender and export it as OBJ... , but they will be converted into segments instead of a curve with handle and perfect shape...

@@rshiya5018 Probably it has to do with the Houdini import of the file. I'm doing some test without blender, importing directly the .ai file into Houdini (you can read .ai files if you save them without compression from Illustrator) and I do see a correct behaviour on the straight lines, but whenever there's a bezier, it bypass that point

@@rshiya5018 I did some other tests, if you save your file as .ai, without compression and compatible with Illustrator 8, when you import it into Houdini, you get all the correct curves (the only problem is it close all the open curves), and you can do a for loop to resample those.

@@ezpepz yes it will close the curves , but if you add an Ends node and set the start to "open" it will be fine , but still it doesnt come as perfect circle , i had to bump up the resolution of the curve to achieve a better curve , thanks for your amazing video and your help <3

Thanks ^^

I was wondering this thing for a bit man, thanks a lot XD

Just checked, wasn't set as "made for kids", but I checked the "off" in the comment thinking it was "turn off comment moderation", actually I turned off all the comments... thanks a lot again XD

Thanks, I actually had also something like that in the original scene, but every time the video seems to long so I didn't added in the video ^^

It does??? Need to check that, I'm used to calculate it manually from Houdini 16 XD

@@ezpepz It does. :) Check the Pop Color node, it's even activated by default there, and if particles actually die, it makes life so much easier. :)

Thanks!

Thanks for pointing that out. I thought the code was more visible. Gonna zoom it or use an external editor in the next one (maybe also crank up the bitrate on the video) ^^

Hi, thanks. I'm not sure about what you mean with "round connectors disappear". Can you explain a little bit more? Yeah you can send me the scene file, maybe I'll get what the error was. You can find my mail on the About page ^^

when I press shift-c, all I get is a rectangle, no round connectors, it would mean a lot if u be so kind as to correct my file, I'm a newbie, where do i send it to?@@ezpepz

@@ezpepz hi sorry for delay; when I go from object to geo editor, the "tubes" disappear, Im on V20

@@skadbone if the "top studs" disappears at obj level, make sure that inside the subnet, the final output node has all the meshes merged in. Sounds something like that.

thank you !-any chance I can send to you a scene file please?

I'll keep it in mind for future videos. Anyway, I made a tutorial about the core concept of this technique ^^ th-cam.com/video/C3MVJUFymAQ/w-d-xo.html

@@ezpepz thanks a lot 🤜🤛🙏

Thanks man ^^. As far as I know, you can export the alembic with the Color attribute stored and I'm pretty sure C4D has no problem reading Alembic. But I'm not sure if you can read that attribute, cause Point datas are quite peculiar in Houdini, but you could try to promote the color to Primitive or Vertex.

at first look, a piece like 2420 or 3069 shouldn't represent a problem. Actually, I started some time ago a Brick Generator with multiple pieces (I basically started following the Iron Man helmet instruction). It's of course a slow process, cause almost for every different brick you have to think and come up with a solution to get a procedural version. As for the technic bricks, it should be fine (of course they would have to have more polygons). I recall I modelled a technic car years ago but in a non-procedural way XD
