Is there a way to check if a volume with a specific name exist in Pyth

[magneto]

Hi,

 

I want to check if a volume with a specific name exists in Python or VEX. Just like you can check if a certain attribute exists using haspointattribute for example.

 

 

Thanks

Iterate over primitives and check their name attribute?

node = hou.pwd()
geo = node.geometry()

# filter volume and vdb primitives by allowed names
allowedNames = ["density", "dens"]
foundVol = [pr for pr in node.geometry().prims() if pr.type() in [hou.primType.VDB, hou.primType.Volume] and pr.attribValue("name") in allowedNames]

# delete other primitives
geo.deletePrims([pr for pr in node.geometry().prims() if pr not in foundVol], keep_points=False)

if not foundVol:
    print("Not Found")

Thanks man, it works. I just thought there would be a function for this to do a quick look up.

Find attribval should be able to do this:
