This is the best channel for Houdini stuff, I can't believe I've been watching so many materials on modeling with Houdini and that YT recommended this channel to me only yesterday. Keep up the good work my man
Thank You for sharing your in-depth and valuable knowledge Erwin. Especially how you breakdown the problem, current non-solutions and how you got to the new solution.
Absolutely amazing! Any chance we could get a tutorial/ more info on the intersections system at the end, they meet the different sized roads so neatly and consistently :) Nonetheless thank you so much for sharing this knowledge.
@@EHoudiniAcademy I would def pay patreon for this also. Yrying to autogen road networks from osm data, always getting stuck on intersections. great talk btw thanks.
do you have any pointers on how to generate the terrain stamps for the roads shown at 5:20? I'm relatively new to houdini, my expertise is only in geometry stuff right now
another tip when resampling scale to a low res using STRAIGHT LINE and up scale it back using INTERPOLATE, or your roads will move every time when using SUBDIVISION CURVES... !!!!!separate!!!!! any curves when using subdivision to smooth them out .....
Hi just trying out your code I'm finding the resample to low res for reducing the bend will not work in every situation like a hairpin turn is there a way you could show to balloon it out instead so the curve dose not lose to much position?
Yes hairpin turns would need that section cut out and redrawn, expanded outward, perhaps inset into the terrain a bit and then resampled again to a suitable resolution. Finally, recombined with the main road it was cut from.
@@EHoudiniAcademy i used the edge smooth maxed out but had issues on looping bends. i guess its not something that can be totally procedural with out human corrections being made helpful stuff learnt allot from you so far thanks
@@Ugly_Baby_Gaming It can, it worked on the Ghost Recon road toolset, but it is tricky, especially when switchback turns are close together as they have to blend. Try resampling the switchbacks at a higher resolution so they lose less detail, and over expand them first to compensate for the contraction caused by the resample. Finally, i'd suggest you find a center point and end point to your expanded turn, cut that out along the road upward direction and use a falloff curve from a ramp parameter to control the expansion look and feel
@@EHoudiniAcademy yer was a few not too many though so all done now ... I have no idea how the merge splines only got 3rd place I just saved at least 4 months work now I found out about it just merged over 15,000 roads in 3 days into 6,000 so easy to use and used the poly scalple for roads with roundabouts... Absolutly LOVE ALL 3 tools you made life saver XXX
You're a wizard, Erwin. Thanks for sharing your extremely detailed technical insight and explanation of how these tools work.

Great content, technically detailed.
Very good! Thank you!
Thank you!

Maybe at some point, it could be a Patron Livestream or short tutorial series.
But, I'd have to make a separate project for this first.

Thank you so much!!

Thank you a lot for sharing this gem!! Amazing work, no doubt.
Can I use this with OSM Lab map
You could use osm data. But you'll have to clean it, because osm data is often very messy.
where are the example files for polyscalpel? plz help
The link is in the the video description.

@@Ugly_Baby_Gaming Thanks. Great to hear its sped up your data handling.
I'm still working on the poly scalpel as well, optimizing it further.
