CSVの書き出し

Nullノードを使ってボタンを押下した時に実行する仕組みをつくる場合
Pythonコードを実行するノードの作成

Pointアトリビュートの値を出力する例

UIにFileパラメータを追加している。

node = hou.pwd()
geo = node.geometry()
 
# UnrealEngineで読み込む形式でCSVを出力する
filePath = hou.node(".").parm("file").eval()
 
# aなら追加書き込みモード
file = open(str(filePath), "w")
 
row = "," + "Name" + ",Cluster" + ",Position" + ",Up" + ",Forward" + ',Scale' + "\n"
file.write(row)

num = len(geo.points())

i = 0
for point in geo.points():
    name = point.attribValue("name")
    cluster = point.attribValue("cluster")
    pos = point.position()
    up = point.attribValue("up")
    forward = point.attribValue("N")
    scale = point.attribValue("scale")
    
    row = str(name)
    row += ',' + str(cluster)
    row += ',' + str(pos[0]) + "," + str(pos[2]) + "," + str(pos[1])
    row += ',' + str(up[0]) + "," + str(up[2]) + "," + str(up[1])
    row += ',' + str(forward[0]) + "," + str(forward[2]) + "," + str(forward[1])
    row += ',' + str(scale)
    file.write(row)
    
    # 最後以外の行なら改行
    if(i < num-1):
        file.write("\n")
        i+=1
 
file.close
