Hi all!

It is possible to render in loop?
For example I wrote some post render script which start mantra again. But I got warning - Recursion in parm callback.

This is Mantra1/postrender script:

i = hou.parm("/obj/control/num").eval()
i+= 1
if i < 10: 
	hou.parm("/obj/control/num").set(i)
	hou.parm("/out/Mantra1/execute").pressButton()

/obj/control/num is for to switch geometry. I want to switch geometry and render it. In this case I have 10 : /obj/geometry0 ... /obj/geometry10
If I press button Render - Mantra1 start once.
Script executed successes but last string. It seems merely ignored.
After render first frame script is started but without continue.

Thanx,
Sergiy

Thanx,  

Take a look at the wedge ROP, it renders a ROP node  n-times and can update parameters for each itteration.
There is a old video about it on the sidefx.com tutorials pages.
