Volume Previs HDA Broken on Install

[tomgiagtz]

Typo in the volume points python code.

x /= reduce
y /= reduce
z /= reduce

bounds = geo.boundingBox()
bmin = bounds.minvec()
bmax = bounds.maxvec()
bstep = hou.Vector3((bmax[0] - bmin[0]) / x, (bmax[1] - bmin[1]) / y, (bmax[2] - bmin[2]) / z) 

geo.clear()

for i in xrange(x):  #<<<======
    for j in range(y):
        for k in range(z):
            p = geo.createPoint()
            p.setPosition((bmin[0] + (i*bstep[0]),bmin[1] + (j*bstep[1]),bmin[2] + (k*bstep[2])))

Fixing produced a float to int casting error.

Didn't take long to fix, I'm going to create a PR for this. Here's the updated version of the volumepoints.py

    if isinstance(geo, hou.Geometry):
        for prim in geo.prims():
            if isinstance(prim, hou.Volume):
                if prim.stringAttribValue('name') == name :
                    return prim;
            
        raise hou.Error("Cannot find Volume with name of : %s" % name )        
        return None
    raise hou.Error("Error: geo parameter is not of Geometry type")
    return None
    
# This code is called when instances of this SOP cook.
node = hou.pwd()
geo = node.geometry()

volumename = node.parm("parm_volumename").evalAsString()
volume = FindNamedVolume(geo,volumename)
reduce = node.parm("parm_reduce").evalAsInt()

x = volume.resolution()[0]
y = volume.resolution()[1]
z = volume.resolution()[2]

x = x // reduce
y = y // reduce
z = z // reduce

bounds = geo.boundingBox()
bmin = bounds.minvec()
bmax = bounds.maxvec()
bstep = hou.Vector3((bmax[0] - bmin[0]) / x, (bmax[1] - bmin[1]) / y, (bmax[2] - bmin[2]) / z) 

geo.clear()

for i in range(x):
    for j in range(y):
        for k in range(z):
            p = geo.createPoint()
            p.setPosition((bmin[0] + (i*bstep[0]),bmin[1] + (j*bstep[1]),bmin[2] + (k*bstep[2])))
