Features

• Creates block_begin nodes at right places on the network, pairing them to the right block_end node. Works for nested foreach blocks.
• Creates compile_begin and compile_end nodes at right places on the network.
• For each node in the block (supports keyframes) :

  • Creates the spare inputs needed by Hscript parameter expressions, and setting it to the right relative node path.

  • Replaces all node paths in Hscript parameter expressions by the corresponding spare input number.

  • Replaces all inputs references in Hscript parameter expressions by the corresponding spare input number.

Future features

The following features may be added in the future :

• support of variables like $CEX, $CEY and $CEZ for example
• non "compile-able" nodes detection
• maybe some kind of workaround for channels referencing channels using parameters expressions

Installation

Download the last stable release of Houdini Auto Compile Block.
Copy the houdiniAutoCompileBlock and packages folders and paste it in your $HOUDINI_USER_PREF_DIR directory.

See SideFX's documentation on environment variables

Usage

Right click (RMB button) on any Sop node. There should be a sub menu called Auto Compile. You will have several options :

Update node

It will convert your Hscript expressions referring to spare inputs instead of node paths or inputs references.

Compile block

It will update all nodes in block, create new block_begin nodes and new compile_begin and compile_end nodes.
