hi

i am really new to Houdini and trying to understand the vast world of it.

i have a query , it might be very silly of me to ask . in vopsop there are so many things i get tangled with and get confused.

** when do we use add and multiply node , fitrange and etc.

** just a random thought Can we scatter in a VOPSOP other than using a scatter SOP.

are there any tutorials which can explain all the basic factors of vopsop .

VOPSOP and VEX Wrangle nodes are just some lower-level scripting tools to create more custom nodes.

Most of the VOPs are just mathematical operators, so if you want to do, and know some basic programming you can spend a lot of time fiddling around.

In the case of a VOPSOP, you should see it as a shader operator, because it operates on all of your points by default. and VOPSOPS at least in <H14 could not generate geometry.

For that you needed an AttribVOP, but I think in H14 they kind of merged AttribVOPs and VOPSOPs, and attributeWrangles and pointWrangles.

 

On the specifics of a scatter node, it would be possible to do in an attributeVOP/Wrangle, but remember that native nodes are usually faster,

except when you can replace multiple nodes with a wrangle, or especially looping structures.

 

I would just suggest searching for VOP in this forum as a whole and download some files that people have posted.

For some tutorials I have this and the following videos in the playlist:
