Mandelbulb C4D Tutorial - no Mandelbulb & crashes immediately

Hello dear team Arnold and everyone who can help me
I try to create a Mandelbulb


But I fail miserably

Spec: Win10; C4d R19; Arnold 2.4.1 Core 5.2.0.0 (Demo)

I follow these instructions:
Mandelbulb Tutorial C4D


i have the file mandelbuld_proc.dll downloaded from the Tutorial above
loaded into the directory C:\Program Files\MAXON\Cinema 4D R19\plugins\C4DtoA\procedurals

I start C4D and create Arnold*:

- *skydome_light
- *persp_camera
- *Procedural
- *standard_surface linked to Procedural

then I click on Arnold Procedural (object) and see:
Main/Type/ Drop-Down Menu/Alembic;Mandelbulb;ASS

Beautiful! Arnold has the plug Arnold has found the plugin and I see a new tab Mandelbulb with a set I can set -> Visibility/Sideness/Receive shadows and so on and so forth below the things shown in the tutorial: Grid size/Max iterations and so on...

but after I click on Render or want to look at it in IPR

"The plugin ai.dll has crashed"



Things I've been trying to do:
Maybe it's the OS and it's a read/write problem so I've got it under:
Edit Render Setting/Arnold Renderer/System/Plugin search patch

and here I have indicated another directory where the mandelbulb_proc.dll is to be found but also this did not lead to any Mandelbulb ...

another mondelbulb_proc.dll from the Maya Tutorial but still no Mandelbulb


Help 🙂

I have the same issue with mtoa, I complied the source file building the mtd file.
And all work fine, I can play with parameters to get variety.

Render with skydome etc.. all work fine

The crah happen when I try to assign any arnold shader.

Even If I copy the mandelbulb from houdini, the crash happen only when I try to assign any arnold shader

The mandelbulb procedural is compiled for Arnold 5.0.1.1. It will crash with current Arnold core 5.2, since procedurals require recompilation for that version (see release notes for Arnold 5.2.0.0). I suppose it should work if you install an older C4DtoA version (like 2.3.1.3, which uses 5.1 core).

Since the source is available, I compiled the procedural with SDK Arnold 5.2 in attachment (.dylib for MacOS, .dll for Windows)

Are you using the re-compiled version from Sen's post? It works.
