  1. Hi, I need to learn how to make this stuff: from the Houdini 18 presentation (min 11:58), this guy just draw a line and gets a tree. Anyone happy to teach how to make it? I'm not interested in getting a tool that does it, I need to learn how to create it. Thanks.

  3. Lsystem

    Hi all! I am wanting to use Lsystems to create trees, I find the tool very awesome when it comes to the basics of creating a tree shape. But I am having issues with leaf distribution and honestly the code is going a little over my head on what I need to do to get the leaves scatter more randomly , right now I can get them to group in threes but I would like a more even random distribution. I have looked at both http://paulbourke.net/fractals/lsys/?fbclid=IwAR3nA-wwniepOGQ2GfJOjkOSCq3DyMmrusNVKGy0ARNEAWD4H8Hpp5jbVzk and https://www.sidefx.com/docs/houdini/nodes/sop/lsystem.html?fbclid=IwAR10o-Y0IfwgRVlLXU2j2h8quGYW1niVRxW1LmTReqonNdeYC8Zo6RdrvFk But again the code is just going over my head on how to achieve what I am hoping to create Hopefully this makes sense
  4. Hi Guys, is there a way to have tree meshes scattered on a terrain with variance in leaf colour on every single tree so that no two are the same colour? back in the Softimage/ICE days i could scatter points on a terrain mesh and give the points a random colour then i'd create a plant or tree mesh with different materials for bark, leaves etc, in Softimage's node based material builder i would plug in an attribute node into a colour mixer merged in with the leaf texture map, this attribute would read the random colour generated on the scattered points then i'd export the tree mesh as a Redshift proxy at render time the proxies would be loaded in, and each individual tree's leaves would be given an individual colour variation within a specified range based on the random colour from the scattered points this would mean each individual tree would have a unique colour added to its leaves and would be quick in the viewport/quick to render because of RS proxies (it also worked for Arnold standins) I've been trying to do this in Houdini but am hitting a wall, I've tried material style sheets but that requires me to create a different override for each parameter i want to control then assign specific trees to those overrides, its still not giving me unique colour variation per tree, its also quite a pain to set up, on top of that mat style sheets don't work if there's more than one material on a mesh which makes it redundant in this scenario I've also tried user data + attributes + shader switch but again you're using a mixer to switch between different specific shaders that you have to individually build, am i missing something? thanks for your help Houdiniers

  6. Pine tree in houdini

    I've been trying to make a tree with a tree top that goes in approaching the top. However, I can't seem to get there. Does anyone have any tips?
  7. Recursive Particle Split

    Hey guys, how can I duplicate particles recursively? Sort of in a fractal / l-system way, to simulate veins, bramches and stuff like this Thx

  9. hey chaps, been a while since i was on here but i've been keeping myself busy! i'm having a little problem with my setup... i've got a tree (modelled in speedtree) and i've brought it into houdini. I've done a pre transform fracture to get 'splintery' pieces. I've set it up so a ball hits it (its a dragon in my scene but its quite heavy geo so dont want to include it!). now overall it 'works' ...as in the ball fractures the tree on impact. But its just lacking that splintery 'connected bendy' feel... eg if you load the sim and play it you'll see the lower half just kinda crumbles away... It would be nice for that to bend in the direction of the impact as if the tree itself is bendy - right now it feels like crumbling chunks of brick that all break apart - it would be nice to get some kind of bendyness in any branches that stay together? another thing is the pieces seem to lack some sort of 'inherit velocity' from the impact. I've followed a heap of tuts online but i just cant figure anything out - is anyone able to take a look at my scene (attached) and see if anything is possible? ta! ant scene included below - tree alembic also included.... i will shower you in MAOAMS sweetys if you can help me with this scene because i'm really lost tree_destruction.zip
  10. Hi! I`m looking into creating a digital asset of procedural trees, with the idea being to generate a hole bunch of pine trees that you can scatter in a background of a shot for example. I`m sort off lost in the whole procedural way, and the L system is way to complicated for what we are trying to achieve all though that might be something to look into in the future. Also is there a way of copying a line with different length the higher up it goes? Lets say you have a line 8 units long with 10 points, I have grouped every other points and want to copy another line on the grouped points, but I need the length of line to shrink with each copy Any tips would be much appreciated.
  11. Hello, today I am facing very difficult problem, maybe you could help me in this struggle. Scenario looks like this: I received animated tree exported from SpeedTree as an alembic file. Now in Houdini it looks like wind is moving leaves which is perfect. The problem is I would like to collide with the leaves with RBD objects which are bouncing around my scene. I would like to keep my “wind” animation on a tree but make the tree responsive to any objects that may collide with it and make it so the leaves would bend on collision. Is it possible ? If so what would be the way to achieve such effect. Have a nice day and thank you for your input in advance. P.
  12. Hello gang, Do you happen to know of any resources free or paid that deal specifically with dynamic trees / vegetation inside of Houdini, with the possibility of also adding falling leaves? Also something to consider is importing an external model. By dynamic I mean coherently animated across the scene, and not necessarily full dynamic trees. This is for a long term personal project so very willing to learn. Thankies.
  13. https://www.hossamfx.org/trees-rigging-in-houdini/ Hello Everyone : this tutorial is about creating and animating trees in Houdini FX in Procedural way . you will learn how to create your own tree model and how to animate it in different weather like windy day, normal wind ........etc. also you will see how to simulate a growing process : what i mean in growing is : you can select at which age of tree you want to start growing to final complete model , so you can start growing from zero or you can grow from winter tree to a beautiful spring tree with leaves and young branches . i will show you firstly how to create a tree model in SpeedTree software for about 1 hour and then move to Houdini and create python code to define the hierarchy of branches and build a procedural wire dynamic network with some math concepts of course . Houdini rigging tools and chops techniques in our list also to add more option and realistic to animation . in the link you can find more description about this tutorial .

  14. Tree and Foliage Tools

    Hey, thought I'd share this here. Preview of tree and foliage creation and layout tools now available on Gumroad. I've released them as "pay what you want" as my contribution to the community. I plan to keep supporting and improving these tools in future as well as releasing other tools. Let me know if you have any feedback/suggestions and I look forward to seeing what people create with them. Enjoy! https://gumroad.com/l/zWFNX
  15. Hi. I would like to ask for an advice for making a tree growth animation in Houdini. If there are some tutorials or any other kind of materials that could help me, I would appriciate if you could share with them Growth happens for around 2 minutes. Tree growth will start like a seed (very small/thin trunk) similirat to this animation but without leaves https://vimeo.com/32134340#t=6s As more branches grow, thicker the trunk becomes. This animation has to be very art directable, so randomly growing is not an option (except the very last levels of branches). My inital plan is to to manuali draw first 2-3 levels of branches (including trunk) and then run it though some assets that I will build wich does the growth (with all the animation controls and etc). I have attached concept images that have to be replicated almost 100%. Thanks in advance! Tom
  16. I'm trying to create a high resolution procedural tree model (without using SpeedTree etc). I looked into L-systems but thats not much use for a more detailed model that is made of one mesh. This is a really interesting tutorial (and has been posted before) - http://www.andyboyd3d.com/siggraph_talk/img27.html But i'm wondering if theres a procedural way to create the branches (seen here - http://www.andyboyd3d.com/siggraph_talk/img32.html). I'm guessing this part was actually done manually but it would be great to have a procedural method! Cheers, Mike

  19. Hi guys. You remember Ivy_generator? I fixed some bugs in it and compile it for Linux 64. Also I created a digital asset for animating it. The exported obj files must first converted by hobj.py to a cleaner houdini friendly obj file. Download ORIGINAL 32bit linux version and replace my compiled version with original one. Have Fun and let me know if you have problems in using it. fa_ivy_tool_v4.otl.tar.gz IvyGenerator.tar.gz hobj.0.1.3.py.tar.gz
  20. Bullet through a tree

    Hey Guys If anyone could help me I would really appreciate it. I'm currently working on a bullet going through a tree but unable to get my desired out come from stretching the voronal fracture points. I've been searching the net for tutorials but haven't been able to find what I'm looking for. I've added the file I've done so far and a link of what I'm trying to archive as the bullet hits the plank. Once again if anyone could help me with this I would greatly appreciated it as increasing the points on the object sim times, hugely increase and still doesn't solve my problem. Tree effect I'm trying to do: http://www.google.co.uk/imgres?imgurl=http://sasquatchinvestigations.org/wp-content/uploads/2011/09/Bigfoot-Close-Break-2.jpg&imgrefurl=http://sasquatchinvestigations.org/bigfoot-research/tree-break-pictures/&h=300&w=400&sz=48&tbnid=mROn9ia0ICI5cM:&tbnh=92&tbnw=122&zoom=1&usg=__GJW8mqjgoaJ8uMMC-OUzjf9FbE0=&docid=bTGv-LvIzuO24M&sa=X&ei=hgRSUYnrC9Gb0AXryoCQAw&ved=0CHMQ9QEwCg&dur=38 Fracture_Bullet_test.hipnc
  21. My current development. Digital asset for creating production-ready animated trees and other plants. A few types of wind (Real time wind system and accurate dynamic wind), many many options to customize plant as you wish. Additional examples of wind animation will be a little later. Basically, you need only 8 hours to create fully dynamical 3d tree. (2-3 hours for tweak a shape and all other time for dynamic) Implemented by python, HDK, and a lot of free time This is noncommercial thing. - Module system for any kinds of vegetation - All in one DA - Maximum flexibility - Fast internal modules based on HDK ( C++) - Auto smooth trunks - Dynamics - Leaves mesh builder http://vimeo.com/58316944 Please, feel free to contact me any time. Thanks.
