~nature~

divergence free means the fluid is totally incompressible and the total volume stays the same over the time, otherwise, it will shrink or expand.

Thanks Tomas,

I still experience the problem, and I use your method to replace the input of surface model node inside mantra surface shader, it doesn't work, there's no effect and houdini proceeds its own way just like the parameter has not been modified yet.

Currently I could only mix a new surface model node inside or just construct a totally new material from scratch.

Is that a bug?

Cheers,
Best regards

Hi guys,

Nice day!

Is there a way to vary the specular angle by procedural noise or texture across the surface, I am trying to modify it inside mantra surface shader without any success, it seems that houdini ignores the effect.

Cheers,
Kind regards,
