I'm loving how 2020 started, with you getting more active in youtube, which is the best present I had. I get hyped each time I see a new video notification
Would love to see (it might have to be a normal non-beginner video) how you would feed this into vellum, with it being a changing mesh every frame etc. thanks
Thank you so much for that tutorial! Any chance you could explain how you would go about merging all the new geometry without merging the source sphere?
How do I export this to use in blender? Alembic did not work for me so I guess VDB is the right one, but I get some hazy thing in the end UPD: As usual I just did the tut wrong. Converted VDB to volume, not to polygons... Thanks! Your tutorials are amazing
Awesome, great tutorial! Question: how do you control which geometry in the solver gets piped into the next frame? What if I want to make it so only a portion of the geometry goes into the next frame?
that was great! thank you! I am wondering if I can transform one of the frames into the polygon I want to use in a future animation. I can't detatch it from the procedural animation or freeze it in anyway
instead of using the switch node, i pplugged prev_frame in scatter node and put the OUT at the end of the node tree within the solver. However, when using the merge node to try to combine the original sphere with the growth effect, it doesnt work. It doesnt grow outword from the sphere, or even show the sphere.
Hi there! I really love the tutorial series - but there is one situation, where my nodes stop working. Maybe its a version issue, but when I create a solver, there is an additional OUT node, that seems to interfere with the way, the tutorial works. Do you have a Quick tip on how to rearrange the nodes so that it works again? Thanks in advance 🙏
At 1:43 "to employ a proper technique the first thing you wanna do is drop down a Switch" - is this still the case in Houdini 19? (Frame 1 seems to display the input geo without needing this.) Also perhaps updated, the Solver provides an OUT node that, when flagged, seems to eliminate the need to go up one level to press play and see the animation.
Ive got two questions 1. Can we slow down the sop solver, for eg: can I make things happening in 20 frames, happen over 40 frames 2. Can I uv map this geo, so that I can do some nice shading. Thanks in advance.
You can UV map by adding inside solver Attribute copy node with name uv and wiring its first slot to scatter (add a node after scatter and before copytopoints), and second to prev frame. Make sure you created uv's for the original object you are using. For slowing down time blend works well setting by speed and fix it or any other node from time shall work either, just wire that after the solver, cheers!
So at the end, we identified that the vdb workflow was slow... but what do I do with that information? Is there a different workflow that can achieve a similar result?
Nope. VDB currently is the most versatile workflow when it comes to those kind of effects. The resource hunger is just a matter of the fact that we're using Voxels here, which are inherently memory hungry. Cheers, Mo
The big thing for speed of workflow in this case would be to make sure to go through the process of tweaking and iterating your solver settings prior to activating the VDB conversion, not after. That way you can dial in the overall shape/speed/etc. without spending too much time waiting around for it to run all the extra processes along the way.
Thanks for these great tutorials! When I add the attribblur node, Houdini comes up with an error: imgur.com/a/exGQIIO imgur.com/a/tCjBOVv Oh, after a bit of googling I found that a little tweaking of the Houdini env file resolves the "Unable to load HFS OpenCL platform" problem. Adding "HOUDINI_OCL_DEVICETYPE=CPU" in houdini.env. imgur.com/a/tn3k17r
Houdini looks so complicated after 1 year with Maya. Sould i scare guyz? I see Houdini vfx's everywhere, i think this software very powerful. I want to try so i was looking for some quick tutorials and here i am. So much nodes damn. Gonna ask again, should i scare? Really nice tutorial tho
Thank you for the wonderful tutorial. I'm in the learning process so forgive me for the dumb questions. I'm trying to remake this animation, i can do it by just following the steps but i want to learn the logic, how do you know just copy the three nodes and paste it under the solver node, how can i learn the logic? I don't want ot memorize the steps but learn it, what should i do? Best regards
I am not sure that's 100% what you need, but for me, it clicked when I tried slowly redoing the same things step-by-step on my own as well as seeing the same methods used in a different context. eventually, I got to understand how it all works better and couldn't but wonder about the brilliance of it lol. good luck to you :)
I like how you sneaked in the performance monitor at the end.

Thank you, we appreciate the support!
Damn didnt Turn out well i guess
This is great!
I'm new to Houdini
I love this series of tutorials so far!
Entagma is the master sensie, so well explained. Thank you so much!
You guys are a great houdini resource. Thank you
Love your content man!! Cant wait to get into houdini
You are AWESSOM @entagma - great tutorial! thank you very much for these!
These are awesome! Thanks for sharing
Brilliant! Thank you.
Would love to see (it might have to be a normal non-beginner video) how you would feed this into vellum, with it being a changing mesh every frame etc. thanks
Clear and straight to the point! 😃
Thanks!
Entegma are the only tutorials I ever have to play on 0.75% So information dense! Not an "ehm" or an "uhm" to be found.
Thank you so much for that tutorial! Any chance you could explain how you would go about merging all the new geometry without merging the source sphere?
So if you wanted to have multiple of these start close to each other and eventually merge into a blob, would you do them under the same geo node?
Yes :D
@@Entagma thank you. really amazing stuff you are uploading, also quite entertaining to watch!
@@TryMike4instance wow cool idea dude!
How do I export this to use in blender? Alembic did not work for me so I guess VDB is the right one, but I get some hazy thing in the end

Awesome, great tutorial! Question: how do you control which geometry in the solver gets piped into the next frame? What if I want to make it so only a portion of the geometry goes into the next frame?
Fix for the new version of Houdini. In geometry level, connect the sphere to input 2 and in inside solver, connect input 2 to switch.
Finally 😍
Thank you for the lesson! But with the old copy to points in the Houdini 17.5 did not work))
But maybe most likely I did something wrong))
that was great! thank you! I am wondering if I can transform one of the frames into the polygon I want to use in a future animation. I can't detatch it from the procedural animation or freeze it in anyway
Cache node or timeshift would be options :) cheers, Mo
Hello guys. How to calculate position for the copyed geo? It's the random point position or it's more straight?
instead of using the switch node, i pplugged prev_frame in scatter node and put the OUT at the end of the node tree within the solver. However, when using the merge node to try to combine the original sphere with the growth effect, it doesnt work. It doesnt grow outword from the sphere, or even show the sphere.

Hi. Same problem here. I got it to work by putting "$FF >= 1" instead of "$FF == 1". Just plugged the OUT node at the end also 🤷🏻
At 1:43 "to employ a proper technique the first thing you wanna do is drop down a Switch" - is this still the case in Houdini 19? (Frame 1 seems to display the input geo without needing this.)

Ive got two questions
1. Can we slow down the sop solver, for eg: can I make things happening in 20 frames, happen over 40 frames

You can UV map by adding inside solver Attribute copy node with name uv and wiring its first slot to scatter (add a node after scatter and before copytopoints), and second to prev frame.

For slowing down time blend works well setting by speed and fix it or any other node from time shall work either, just wire that after the solver, cheers!
looks like the three nodes that we copy into the solver1 aren't needed in the upper level anymore

Can this go in a game engine to be used in a game ?
عالی

Seeing your history of weird error messages when using standard tools, it might be a good idea to do a fresh clean install of Houdini... Cheers, Mo
