  1. Hi In my scene I have a null node called "Precise_Clipping "where I edited the parameter interface and added a toggle called "precise_clip" then In the voxel size channel of a vdb node I have written the following: if (ch("../Precise_Clipping/precise_clip") == 1) { return 0.01; } else { return 0.2; } The problem here is that it gives this error: http://prntscr.com/cg15f2 Its not the first time I write expression in channel fields, and to me the syntax looks correct...so whats the error? Thanks
  2. Hi Please consider changing the default background for the style for "No Syntax Highlighting" to a brighter color. As it is now it's almost impossible to read. I seems a lot of people leave this setting at default, which is fine but please make it easier to read. Something like this will be more than sufficient: pre.ipsCode{ background: #ccc; }
  3. VEX syntax definition for SublimeText

    Needs some polish, especially in regards to multi-line macros. Additionally, it'd be nice if vex had a header extension that didn't clash with c/c++. I'm manually specifying .h files as vex headers as needed, though the definition picks up vfl's automatically. https://gist.github...._tmlanguage-xml What it looks like with the Monokai Theme: Have Houdini related SublimeText enhancements to share? Snippets or build systems? Lets collaborate! -shawn
  4. I'm trying to learn houdini, and one thing which I'm getting really stuck at is the syntax and (apparent) inconsistency of expressions / snippets of code - or at least there's so many little idiosyncrasies that it's driving me nuts. I've looked around as much as I can in various documentations, but couldn't find a single piece of text which describes an overview of all of these things, instead the info is scattered all over the place, probably because some of these are legacy and dates back decades while others are quite new. As far as I understand: $ is for global variables (in HSCRIPT ? and python too? are there substitutes for VEX?) @ is for attributes in VEX (is it possible to access attributes in HSCRIPT?) ch is for referencing a channel (i.e. a parameter of something from the GUI?) (is this HSCRIPT? or PYTHON?) I'm still not sure what op or ` (backtick) are for or when to use them. What I'm after is a very short (hopefully not more than a few sentences per item) summary of what each of these things are, and in what context we are supposed to use them. Also, what is the context of what we enter into textfields? E.g. when I write sin($T) into the position of an object. Is this HSCRIPT? or Python? Or is that a Houdini Expression which is a whole other context separate to HSCRIPT? cheers,
