Yes, I agree. It would be wonderful if the installation was >200MB smaller but I think that a significant portion of the program is missing and will not install.

While environments are slightly different for the existing systems, patience is required.

For Windows 10, Houdini 15.5 (I use indie), and Renderman 20.9:

Make sure Houdini is closed.

Using a text editor of your choice: I use Notepad++:

Open: C:\Users\(name)\Documents\(Houdini directory)\houdini.env

Where:
(name) = Windows Login Name (Check your User directory)
(Houdini directory) = Folder where Houdini preferences are saved, (Check your User\Documents directory)

Example: C:\Users\Rob\Documents\Houdini15.5\houdini.env

Add the following lines (note the direction of the slashes)


RMANTREE="(Drive)/Program Files/Pixar/RenderManProServer-(Version Number)“
PATH=”$PATH;$RMANTREE/bin"
HOUDINI_DEFAULT_RIB_RENDERER=prman(Version Number)


Where:
(drive) = C:
(Version Number) = installed Version, in my case 20.9

EXAMPLE: For those who may copy these, lines there is an extra space between C: and / for display purposes to prevent in the first line - REMOVE THE SPACE

RMANTREE=“C: /Program Files/Pixar/RenderManProServer-20.9”
PATH=“$PATH;$RMANTREE/bin”
HOUDINI_DEFAULT_RIB_RENDERER=prman20.9

Save the file.
Close the text editor.
Restart Houdini (or in my case Hindie.exe)

I was able to run the test file provided by tinyhawkus and the new renderman tutorial from Pluralsight.

THESE ARE NOT ALL THE STEPS REQUIRED. REFER TO HOUDINI HELP FILE FOR 15.5:
You will need OUT: Renderman RIS & SHOP Network, SHOP: Renderman Material Shop. Addtitional: Pixar materials, Pixar Lights.
