    You can use channel reference or use the bbox() hscript function for the box size and the centroid function for the Box center.

    It's the same a "normal" python scripting : import module1 import module2 import module3

    Hey thank you very much for your reply, This look really cool, however I have to say this is too advanced stuff for me. But I will surely try to dive deeper on it once in a while. Maybe I am just trying to do something too complicated for my current skills... Thank you again for sharing this which look tremendous!

    in find_nearpoints replace this i[]@nearpts = nearpoints(1, "!grp", @P, .1, 4); with this string grp = "!grp" + itoa(i@source); i[]@nearpts = nearpoints(1, grp, @P, .1, 4); or alternatively you can completely bypass your set_lines_grp as you don't need to have those groups, because you can use ad-hoc group syntax in nearpoints directly: string grp = "@source!=" + itoa(i@source); i[]@nearpts = nearpoints(1, grp, @P, .1, 4); VEXgrp_01_fix.hiplc

    Set the "Missing Frame" option to No Geometry on the file cache.

    well, yes, because I left the one you had inside before, just fixed to work on Geometry and be point, so you can just delete or bypass it if you don't want to set it dynamically vu_GrainsVellumSOP_fix3.hiplc

    Mainroad Post started posting some classes online. For now there are only 3, it's in russian but it's easily followable and very very very interesting; it deals mainly with vops and maths, and how you can construct patterns using maths functions such as sins, noise, etc.... Very intructive.. https://www.youtube.com/watch?v=rzjXRvgo7YA 1/7 https://www.youtube.com/watch?v=2SSCN3WBne4&t=4591s 2/7 https://www.youtube.com/watch?v=LF4ZUchXU6Q 3/7 And i assume the following will be released soon as they started posting a week ago. Cheers,

    Group the faces and run a remesh on that group. To make the grouping easier for topology like this you could use a measure node to get the area of each primitive and then just group each prim over a certain area

    I got some help on the RedShift forum about this issue and here is the fix. You have to edit your Houdini.env file to point to the RedShift render engine. Here is what my .env file looks like now with RedShift and Rendman both working under Houdini Indie. RMANTREE="c:/Program Files/Pixar/RenderManProServer-20.9" PATH="$PATH;$RMANTREE/bin;C:/ProgramData/Redshift/bin" HOUDINI_DEFAULT_RIB_RENDERER=prman20.9 HOUDINI_DSO_ERROR = 2 HOUDINI_PATH = "C:/ProgramData/Redshift/Plugins/Houdini/15.5.523;&" Also you must match your Houdini install version to the Redshift plugin version. As you can see from above RedShift will only work with Houdini 15.5.523. If the versions don't match you can't use RedShift and you get an annoying popup error message every time you render even if you are using another render system.
