I'm trying to understand the tutorial "How to Render a Mandelbulb" and I'm stuck at how to
animate (for example the grid_size) a given parameter. I understand that I have to set up aiUserDataFloats and I succeeded in altering the shader, but I dont get the connection from setting up custom attributes which controll this part of the .ass file.
grid_size 400
max_iterations 5
power 6
etc.
Can someone point me in the right direction?
Hugs,
Paul

HI, instead of loading the ass file in newer versions of MtoA you can create the node directly in Maya.
You need to do a little setup and this functionality is still work in progress.
First copy the attached mandelbulb-proc.txt file to the same location as the mandelbulb_proc.dll(.so/.dylib) rename it to mandelbulb_proc.mtd.
Now add the location of the mandelbulb procedural in your ARNOLD_PLUGIN_PATH environment before launching Maya.
A new menu should be available under Arnold called Custom Shapes, under this menu will be a list of found procedural nodes from plugins in the ARNOLD_PLUGIUN_PATH, mandelbulb should appear in this list.
Once you create it, a null node will be made in the scene with a transform as a parent. I usually make a volume cube as a child of the transform so I can visualise the location of the Mandelbulb in the scene.
you can now assign shaders and change the parameters directly.
