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.

Thank you Michael & Goat

Michael,

The camera rig solves the problem exactly, on the other hand the Lamp asset appears to reveal the limitation of the “apartheid”. Lets say I want to place this lamp and light on an apartment floor and instance the floor, it does not allow me to object merge the digital asset as it is a “invalid SOP”.


Now my workaround is either to create points with the lamp geo and pull them out after scattering the lamps and instance lights on OBJ level or pull out objects to make mesh lights. This just adds an extra laborious phase of work to the process that appears unnecessary.

I may be still in the 3DS MAx mindset and not getting it but what I would expect to be able to do would be to copy the asset onto a grid and the light goes along with it…
