In C4D this is fairly simple to setup, but how can I create a Mandelbulb Vectron in Houdini, where do I get the code for this? Is it even possible if I have no knowledge of OSL?

Hi,

The Vectron objects in Houdini are configured adding an OSL shader with the OSL code to the vectron options available in the OBJ spare parameters. Attached you have an example scene if you want to take a look at it.

Thanks, exactly what I was looking for!

Hi,
I recently switched from Lightwave to Houdini, and was happily surprised that my collection of Vectron formulas works without any change.
So, if you are looking for formulas, you may have a look here: https://github.com/thargor6/FFVectron

Cheers!

P. S.: Thanks Juanjo - the Vectron-stuff works so MUCH better in Houdini, so I will probably even revive the FFVectron-project and will add more formulas in the future.

Juanjo, could you include this example file with the plugin? I tried to find this example file many times, without success, and randomly found this topic.

+1, would love some samples included as is the case with the other plugins.

I've tried in Houdini, but how can you specify the path to ff-vectron ?
thanks

It's a bit of a mystery, it works on my machine (without any obvious changes to settings ), but I can not duplicate it.

But, I have found a workaround: You can use absolute paths. It is not really nice, but it works: just edit each formula you want to use and exchange the "ff-vectron-h" by the actual path to this file on your hard drive.
(It is at least a lot better than copying the contents of the ff-vectron.h into each formula, which also would work).

Please let me know when you have further questions (I'm not really often here, but from time to time).

Cheers!

Except it ain't that simple. What's the function _wipes() all about? The time variable also is connected to the shutter, not frame. Basically this, the one singular example of how to get this thing to animate doesn't work. I can find absolutely nothing online about this, how did you come across it?
