Random Textures skips some and duplicates others, how to make sure one of each is picked? Sept. 15, 2019, 3:41 p.m.


I am applying random image sequences to a bunch of planes. Everything works but the random function spits out duplicates and triplicates of some textures. Is there a way to make sure it picks at least one of each of the 80 textures in the range specified by the fit function?

There are 80 folders numbered 1-80, in each folder there is an image sequence “IGS.png”:

the string value for the local override is: “ERENDERS/BATCH/`floor(fit01(rand($CLASS),1,79))`/IGS`padzero(3,$F%431)`.PNG”

The random function calls a different folder for each primitive. But as you see in the Geo Spreadsheet I get triplicates and duplicates, some folders are skipped entirely…

I solved it in a way by simply making this “ERENDERS/BATCH/`$CLASS+1`/IGS`padzero(3,$F%431)`.PNG” Then each primitive calls the folder but if the number of primitives increases and there is no corresponding folder I still want them to get assigned a texture….

Any advice is much appreciated..

Houdini Top node: Imagemagick error. March 18, 2019, 4:38 p.m.

I am having the same issue. I have installed Imagemagick and edited the houdini.env with this:

PDG_IMAGEMAGICK=“CProgram Files/ImageMagick-7.0.8-Q16/magick.exe”
PDG_FFMPEG=“CProgram Files/ImageMagick-7.0.8-Q16/ffmpeg.exe”

I still get a problem.

The Houdini help page is here: []

but I cannot seems to understand what I have done wrong…

OK so its really a limitation.

It seems like quite a simple and fundamental thing so I thought perhaps I was missing something. Considering the awesome power of Houdini this is a bit baffling, there is so much to love.
