Artists can selectively "break" energy conservation.Flexible controls are not required to result in something physically plausible.Physically based presets provided to get you started.A single material handles all your looks like:.As such there are some important benefits to this material: This is the same material model used in Pixar Animation Studios' feature animation.

I think any 1.0.x flavor of these will work (like libssl.so.1.0.2) 4) You need to create two symbolic links in the Renderman-Installer subdirectories to point the installer to those libraries: ln -s /usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 /opt/pixar/RenderMan-Installer-ncr-23.4/lib/3rdparty/Qt-5.6.1/lib/libssl.so ln -s /usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0 /opt/pixar/RenderMan-Installer-ncr-23.4/lib/3rdparty/Qt-5.6.1/lib/libcrypto.so Replace the library and Renderman versions with the ones you have/are installing 5) For Pop_OS (and probably other Ubuntu-flavors), I found that you will also need to manually install the shared libtinfo.so.5 libraries: sudo apt-get install libtinfo5 6) That should do it. It will be named something sexy like RenderMan-InstallerNCR-23.4.0_2090532-linuxRHEL7_gcc63icc190.x86_64.rpm 2) Installing the rpm file should get you an /opt/pixar/Renderman-Installer-ncr-XX.X directory 3) Before the next steps, you'll need to make sure you have the libraries libssl.so.1.0.0 and libcrypto.so.1.0.0 in your /usr/lib/x86_64-linux-gnu directory.

Here are the steps I followed to get RenderMan 23.4 running in Houdini 18.0.532 on Pop_OS/Linux: 1) Download and install the Renderman installer rpm.
The ‘could not initialize’ error is indicative of missing libtinfo5 libraries, which you only find out about if you try to run a supporting app like txmake from the terminal.
