Tips and Tricks This section will contain
tips from class and frequently asked questions as appropriate
- SideFX has a new look Under Learn/Learning Paths - three tracks for beginners/intermediate/advanced
- There are now so many resources available, my top picks are (and all free):
TIP: anytime you see a new node introduced read the documentation included by clicking on the ? button in Houdini
For those of you starting Houdini do not ignore the
documentation. Two important user forums exist:
Some of the older tutorials
exists on the vimeo channel Go Procedural (November
2010, Houdini 11). The pdf versions are no longer accessible. (Go Procedural User Guide, First Steps, Next Steps). These are quite dated and there are many more resources available, however much of the information contained is valid.
TIP: vlc has a feature under playback that allows you to play videos at faster (or slower) speeds. The SideFX tutorials can be downloaded from the vimeo page. This sometimes helps when you are searching for something specific.
is your friend - the search engines in the forums don't always
give you the answer you want - search on google and then look
for the forums in the results.
GENERAL - in addition to the resources listed
- In the Houdini Help documentation, review the pages linked to in the “Getting started” section of the Basics page. The pscale attribute that was added in order to vary the scale of the trees in the procedural forest is described briefly in Instancing point attributes as part of the Copying and instancing documentation. More importantly read about Packed Primitives.
- You also should do a cursory review of
- Expression functions and
- Global expression variables
- Global Anim Opts
- Edit Parameter Interface window
- Beginning Houdini User's here is Andy Nichols cheat sheet - this is a good synopsis of useful documentation.
- A brief intro to modeling (part 1), shading (part 2) and linear workflow (part 3) of Peter Quint's Pills Scene videos is highly recommended
- A brand new CGWiki for Houdini is out - really like the comparison to Maya
- gridmarkets (cloud rendering for Houdini) also has featured artists on their site
- These are for version 14, however the
information is still valid: Houdini
- H14Intro - my mini overview for beginners of the interface here
- H14RenderToFiles - mini overview for beginners to render to files here
documents for rendering since 12.5 and up are more
"opinionated and focused on practical advice and tips".
- rendering basics
- Render Quality and Speed
document (12.0) about understanding rendering is still
worth a look
- For the majority of what you do, you will be using PBR. You will see noise in your renders - be sure to read the section on noise level, ray samples and pixel samples in the documentation noted above
- Third party rendering (Arnold) is available for Houdini on Linux and the Renderfarm, however the Apprentice version does not support this and Mantra will be used for 350/721
- odforce post Nov 14/2012 an excellent explanation by Jeff Wagner (old school) on understanding PBR (thanks Zach Z!)
INSTANCING AND PACKED PRIMITIVES
- Packed Primitives
- Procedural Corn Maze by
Scott Keating (I have
created a document highlighting some of the essential features
of Instancing here that
you will need for 350/428.)
- however instancing is an important concept and will be
discussed as it relates to lighting
