And with the Houdini Engine plugin, users of other 3D tools can now incorporate Houdini's procedural power into their workflows. These tutorials introduce the fundamental 3D concepts modeling, animation, texturing, lighting, and rendering as they apply in Houdini. Instructor Scott Pagano shows how to manipulate geometry; apply materials; add lights and cameras to a scene; render work with Houdini's internal renderer, Mantra; and even create simple particle systems.
The course will start new users on a path to more advanced 3D work and show experienced users of other 3D packages how to transfer their skills to the world of Houdini. Topics include: Setting Houdini preferences Modifying geometry Copy stamping Setting keyframes Manipulating animation channels Shading and texture mapping Lighting scenes Rendering with Mantra Creating particle emitters.

Now that I've been using Houdini for a little while, and knowing that SOuP is heavily influenced by Houdini, it seemed like a good idea to try and port those tutorials over. I've become the Houdini evangelist I always despised, and I apologise for nothing. It really is a great piece of software, warts and all, and it's easier to get into than ever.
Do it! If you've landed here and you're totally new to Houdini, maybe head to HoudiniGettingStarted first, has a quick overview of how to use this site, and how to get comfy with Houdini as quickly as possible.
Same as before, just type 'Cd' in the list of transferred attributes. If you want more than one attribute transferred, separate them with a space. Eg, you want to transfer colour, normal, and pscale, you'd type "Cd N pscale".
I added a colour node to the grid to make it red, another to make the sphere green, so you can see what's going on. Why 'Cd'? Houdini uses a lot of naming conventions derived from prman.
Cd is 'colour diffuse'. This was for the point sop in H It's been replaced with a vex equivalent, but its so fiddly to use, you're better off using the vop and vex versions of this below. I rant a bit further down that no-one should use a point sop anyway, the 'improved' point sop is so strange and fiddly to use, it seems SideFx agreed.
Houdini, as well as having the renderman style parameters, often uses variables with capital letters and a dollar sign, called local variables to be used in hscript expressions. These can usually be found by looking at the help for that node, and scroll down to the 'local variables' section. Some older or esoteric nodes don't have any local variables defined.
Usually Houdini folk see these expressions and say 'ah, hscript'. Strictly speaking, houdini expression language and hscript are two different things in the way that maya MEL and maya expression language are two different thingsbut no-one can be bothered to say 'houdini expression language' out loud, and HEL sounds wrong. Houdini defines global, standard and local variables as different things, but again, local variable is the usual short-form. If you look in the scene above, you'll see next to the point sop is a point vop that does the same thing in H13 and earlier called a vopsop, or an attribvop depending on what you needed to do.
I explain vops a little more in Houdini Vopsbut basically vops is a way to write very very fast operators. Maya expressions, python, hscript are all interpreted scripting languages, and can run into performance problems as scene complexity rises.
Vops are compiled multithreaded code, and scale much better. The closest Maya equivalent would be trying to write your own deformers in hypershade nodes, but more versatile. Point sops and hscript are how people traditionally used houdini, but the more you can push stuff into vops and vex, the better you'll be.
In this case, it kind of helps to think of the vop network like a flowchart, reading left to right. First, the setup:. They flow left to right rather than top to bottom. In a vops network, the houdini chant that 'everything is points' becomes very important. Anything you do in this graph is run on all the points of your geometry simultaneously, or at least as simultaneously as your computer will allow.
The leftmost node represents a single point, and all its standard built-in attributes; position, colour, normal, id etc. The rightmost node represents the final output of a point.Info: This release is nothing to do with any previous xforce release, no hacked keygen copycat crack etc.
New Vellum multi-solver brings fast cloth to Houdini along with other integrated effects such as hair, soft bodies and grains.
The Vellum solver is GPU-accelerated and very easy to set up and iterate. The White Water solver has been rewritten to achieve a more organic, foamy, look with realistic cellular patterns and repellant forces and a more accurate relationship to the source FLIP sim.
Material-based destruction tools make it easier to set up and art direct destruction shots by providing tools for pre-fracturing materials such as concrete, glass and wood while automatically building constraint networks that tie the whole system together. Terrain now includes advanced erosion tools with more control over details such as fluvial lines, river banks and debris and new hierarchical scattering for more efficient placement of elements into landscapes.
New UV tools define a fully procedural workflow that starts with automated seaming then moves on to accurate flattening and super efficient layout of the resulting UVs. The new Retime SOP node is a powerful tool for stretching out or slowing down simulated data such as fluid sims, RBD sims and even volumes with effective interpolation and blend options for creating clean and entirely realistic results. Interactive modeling includes a new PolyDraw shelf tool which lets you use our interactive?
Topo Build? Improvements to snapping and alignment including fast construction plane alignment and positioning; rotation snapping; view and construction plane memories; and new geometry alignment tools.
Character animation and rigging have been improved with a newly designed timeline that supports a more animator-friendly keyframe workflow and a facial auto-rig for a complete top-to-bottom auto-rigging solution.

You can apply transformations progressively to each copy. So, for example, you could copy a box model into a line-up of identical boxes descending in size.
Copy the first input source geometry onto the points of the second input template geometry. This is very useful for populating scenes with geometry with full control over the placement of the copies. For example, you can arrange copies in a spherical shape by copying them onto the points of polygonal sphere.
This operator is especially useful for copying geometry onto the points output from a particle system that is, a POP network SOP. Whereas particle instancing displays the instanced geometry at render time and is more efficientusing the Copy SOP gives you "real" geometry in the network that you can further manipulate.
See copying and instancing for more information.

Click the Copy to Points tool on the Modify tab. Select the source geometry you want to copy and press Enter. Select the target geometry on whose points to instantiate the source and press Enter. See instancing point attributes. When making multiple copies not copying onto pointsuse the NCY number of copies local variable in an expression to make values independent of the number of copies.
You can create multiple copies around an axis, then skin them to create complex lathe-like effects, similar to the results of the Revolve SOP. A subset of the source first input primitives to copy from.
You can create groups with the Group SOP. A subset of the template second input points to copy onto. Please note, that only point group specifications are valid for this parameter. Rotates copies to face the template point normals. Also applies translations, rotations and scales according to the trans, rot, and scale point attributes on the template points if these attributes exist.
Amount of shearing. If enabled, keep local copies of the input geometry for each set of stamp parameter values. If there are a fixed number of input geometries which are repeated multiple times, it can improve efficiency by avoiding the recooking of the input geometry. Pack the input geometry into an Embedded Packed primitive before copying.
This results in the input geometry being shared by each copy rather than being duplicated for each copy. Any point attributes on the template geometry that match this will also be stamped. They will be stamped as stamps of the same name as the attribute. Float and integer attributes will stamp their first value as a float. String attributes will stamp as strings. Token and value of each stamp variable. Changes values of parameters which include param function. Copy attributes from the template points onto the copies, according to the values in the attribute fields below.
The columns represent possible ways of combining the attributes from template geometry with the attributes from the source geometry. The rows represent the different entities you can copy attributes onto : points, primitives, and vertices.Copy Random Objects to Points
The total number of copies that will be created the value of the Number of copies parameter. The point number of the Template being copied onto.
If there is a template group, this will be the index into the group, not the actual point number. Use TPT to always get the actual point number.

Adobe Premiere Rush CC v1. Boris FX Silhouette Adobe Premiere Pro vSo when I first started learning Houdini I would jump in and try to recreate simple scenes that I would often do in Cinema 4D.
One of them was to randomize uniform scale on a bunch of geometry. Simple enough. I would start to create the scene and then realize I had no clue how to do it. So this QuickTip is for all those just starting out.
Keep in mind this is just a starting point. Attributes are the secret sauce to a lot of things in Houdini. You need to understand them because most things in Houdini revolve around attributes. I wrote a post that explains them a bit. The use of attributes is a simple concept to grasp but typing in arbitrary keywords could be a bit intimidating when first starting out.
Most of us are just accustomed to moving sliders around or checking off a checkbox. First, a scene setup. You should now see a bunch of boxes copied to each point on the grid. Basically a Cinema 4D cloner. What we want to do next is randomly scale each box. This requires a pscale attribute.
This attribute is the uniform point scale of the geometry. So you may be wondering where does this pscale attribute go? On the box side or grid side or after the Copy to Points node? Who bears this responsibility? Well, what you want is to vary the scale of each box. If you randomize the point scale, when each box is copied to each point on the grid, each box will have a different scale value.
The box will read the pscale attribute in order to scale itself. Hit tab and type out point. Insert it after the grid and change the attribute parameter to Scale pscale and under the VEXpression parameter dropdown, select Constant Value.
Now you can scale your boxes up and down using the slider. Open the Spreadsheet to see the attribute with its corresponding values. However, we need to randomize each value because right now all the point scales are the same. Go back to the VEXpression dropdown and you should see a few presets for Random values already setup for you. Select any of them and you should see randomly scaled boxes.
Also, check your Spreadsheet and see how the values for the points have changed. Get into the habit of using your Spreadsheet! Another way of creating the pscale attribute and randomizing it is by using the Attribute Create SOP.
This one takes some typing but very little. First thing you want to do is change the name parameter from attribute1 to pscale.
