The document provides instructions for installing and using Radeon ProRender (RPR) within Houdini. It discusses importing geometry and materials, assigning materials, setting render variables and settings, exporting for rendering, and using toon shading mode. The key steps are to install RPR, set the viewport to RPR, import geometry into a stage using SOP or scene import nodes, create materials in the material library, assign materials, add render variables and settings nodes, and export using the RPR export node.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:

4. Installation – Automatic Installation
This is the easiest method
of installation, known as
the Automatic Method,
locate your Houdini Preference
directory and add the hdRpr package
that will point it to the
current directory.
When your hdrpr download is
complete, unpack the zip folder and
open the folder located inside.
Double-click on the
activateHoudiniPlugin executable.
A window should appear saying that
the plugin has been activated. Once
complete, open Houdini to confirm
that the installation was successful.

6. Viewing RPR in Houdini
Radeon ProRender utilizes Houdini's Solaris Tools and
LOPS or Lighting Operator nodes, which work to
generate and modify Universal Scene Description
(USD) based scenes.
There are several workflows that allow you to use the
RPR plugin, but in each workflow, the viewport must
be set to the RPR perspective.
6
7. Viewing RPR in Houdini – Solaris desktop
Once you've opened Houdini, Houdini's desktop interface
is set to Build by default.
Go to Build in your 3D viewport and select the Solaris
desktop option.
This will change Houdini's desktop to the stage network,
as well as open the Scene Graph Tree and Scene Graph
Details panes.
In your 3D viewport's perspective
menu,
find and select the RPR option to
make it the active renderer.
BUILD > SOLARIS
7
8. Viewing RPR in Houdini – Stage Network View
Another way to utilize RPR's features is to simply switch
from the object network to the stage network from
the Network View pane.
Once again, setting the active renderer to RPR in the
perspective viewport.
NETWORK VIEW > Other Networks > Stage
8
9. Viewing RPR in Houdini – Perspective Viewport
If you have any issues with your viewport, you can always
select Restart Render in the perspective menu to
reset the stage.
Houdini GL Perspective
RPR Perspective

10. Viewing RPR in Houdini – LOP Network
LOP Network
You can also create a LOP Network node inside your
Object Network if you aren't working entirely in RPR to
create your scene.
Add the node and double click to enter the network.
Obj > TAB > LOP Network
10
12. SOP Import / Scene Import
SOP Import node
If your imported SOP data has subgroups to
separate the primitives for material assignment in
the Object Network, be sure to activate the
Subset Groups option in the Import Data sub
menu and list the geometry's group names with a
space in-between each.
The SOP import node imports geometry from the
Object network into a stage or LOP network.
find SOP Path and open the Operator chooser and
select the geometry you want.
SOP IMPORT > SOP Path >/obj/...
SOP IMPORT > Import Data > Subset
Groups
12
13. SOP Import / Scene Import
Scene Import node
The Scene import node is similar, but can also
import cameras and lights from the Object
network into the stage or LOP network.
SCENE IMPORT > Objects > /obj/...
To do the same for importing pre-
existing cameras and lights from the Object
network into the stage or LOP network, you can
select the Scene Import (Cameras) or (Lights)
nodes.
13
14. SOP Import / Scene Import - Merge
Merge LOP
The Merge node takes multiple inputs (in this
case, one or more USD layers) and merges them
into a stage containing one layer stack in the
output. This is useful when you want to combine
separate pieces of a scene graph, each authored
by a different chain of LOP nodes, into a unified
whole.
14
15. SOP Import / Scene Import - Sublayer
The Sublayer node imports from external USD and
USDA files or other LOP node chains into new
Stage or LOP network as sublayers or instances
that have already been made in other .hip files.
You can import USD elements separately or
import entire scenes using this layer.
Sublayer
SUBLAYER > Sublayer File > Desired File Path
15
16. SOP Import / Scene Import - Test Scenes
RPR for Houdini test scenes (including the scene
used in this tutorial) can be used for
comprehension and experimentation using basic
Houdini assets within a standard hdrpr
workflow. These test scenes can be found here:

16
18. Object ID / Geometry Settings
The Render Geometry Settings node
will apply renderer-specific geometry
settings to geometry in the scene
graph.
Having multiple objects in a scene will
require each of them to have this
node if you wish for each of them to
have separate Object IDs.
Setting the ID option in the RPR
Submenu will change the color of the
designated geometry randomly for
easy viewing.

The Material Library node translates
shader VOP or Vector Operator nodes
into USD material primitives.
The RPR Uber Shader is a multi-purpose
shader intended for creating a wide range of real-
world materials.
It consolidates a number of components, or layers,
that group certain properties of physical materials.
The RPR Toon Shader is a shader intended for the
mimicry of cel-shaded color with sharp shadow
tones and highlights.
The USD UV Texture material can also be applied
to the color for mutliple materials. 20

26. Material Library/ Assign Material – MaterialX Library
RPR MaterialX Library Toon Shader Update
As of Hdrpr version 2.0.46, The RPR
Toon Shader has been updated to
include base RGB Color control
parameter.
The RPR Material Library is a
prebuilt directory with preset
materials that can be downloaded
from the Radeon ProRender
documentation website.
The Import Material function located
in the RPR dropdown menu will open
a new window will appear revealing
the library preset list, complete with
images showing each material's
characteristics.
26
28. Material ID Properties
RPR Material Properties
MATERIAL PATH > Desired
material path
The RPR Material Properties node will apply
renderer-specific material ID settings to the
designated Material path.
Having multiple materials in a scene will
require each of them to have this node if you
wish for each of them to have separate
Material IDs with separate numbers.
Setting the ID option will change the color of
the designated material randomly for easy
viewing.
ID > Desired Material ID Number
28
30. AOVs / RPR Standard Render Vars
RPR Standard Render Vars
Render Variables in Houdini are
referring to Arbitrary Output
Variables, or AOVs.
AOVs can be extremely useful for
examining various aspects of a scene
and can aid post-production
processes.
To use these, add the RPR Standard
Render Vars node.
You will see a checklist in
your parameters pane that includes
multiple AOV modes.
Below is a demonstration to what
each AOV may look like in the
viewport.

36. AOVs / RPR Standard Render Vars – Motion Blur
Though workflows may vary, achieving a Motion
Blur effect in RPR for Houdini is possible using any
node capable of changing a primitive's transform.
One example of a typical workflow that allows for
this is the Xform or Createxform node.
This node belongs to a class of nodes that create or
edit USD prims directly. This node operates in
Create mode or Edit mode.
Xform
Transform
Another example of a typical workflow to achieve a
Motion Blur effect is using the Transform
node. This node edit the transforms of USD
primitives.

Once you've set your RPR Render
Vars node, you'll need to add the
Render Product node.
The Render Product node sets your
variables, your camera and your
output resolution.
First, set your Ordered Render Vars
parameter by establishing the Render
Variables that correspond to the
AOVs you checked off in your Render
Vars node.

Once rendering is complete, check
the folder you specified in your
Windows Explorer, and you should
see your completed exported files.
You should have and .RPR file, and
.JSON file and several .RPRSB files
located in the desired export folder.
RPR files are the geometry data per
frame.
RPRSB files refer to texture,
geometry, and material cache files.
.JSON files record all other
information, including your
designated Render Variables.

Internal rendering within Houdini is
also possible. The USD Render ROP
node writes the USD generated by a
LOP network to a temp file, then
launches an external process (by
default, HUSK) to render an image or
image sequence from the USD.
Similar to RPR Export, if you're animating
a camera, or running a simulation, be
sure
to set the Valid Frame Range to
Render Specific Frame Range.

Saving your file to disk will render out your beauty
AOV as a single file or a sequence of files if you've set
your animation output correctly. Rendering to MPlay
allows you to view your image or sequence once
rendering is complete in the MPlay Viewer, a separate
render viewing window. You can also switch between
the designated Render Variables or AOVs and save
them individually.

When you are ready, you can select
