根据不同项目,节点路径需要相应的修改,旨在快捷键修改.

当前代码中缓存路径为Linux
其中所有$均为houdini内部的环境变量

# -*- coding: utf-8 -*-
import hou

def mess(count):
    message = ' 设置了{0}个节点'.format(count)
    print('-'*14)
    print(message)
    print('-'*14)
    hou.ui.setStatusMessage(message, severity=hou.severityType.ImportantMessage)

def main():
    hip_name = hou.expandString("$HIPNAME")
    if hip_name == 'untitled':
        hou.ui.displayMessage('先保存文件')
        exit()
    try:
        parent_node = hou.selectedNodes()[0].parent()
    except:
        hou.ui.displayMessage('至少选择一个节点')
        exit()
    task_node = parent_node.parent().parent()
    all_nodes = parent_node.children()

    cache_path = '$HOME/geoCache/$PROJ_NAME/$SHOT_NAME/$HIPNAME/{0}/$OS/$OS.$F4.bgeo.sc'.format(task_node)
    count = 0
    for node in all_nodes:
        node_type = node.type().name()
        if 'filecache' in node_type:
            node.parm('loadfromdisk').set(True)
            node.parm('filemethod').set(1)
            node.parm('file').set(cache_path)
            count += 1
        elif 'vellumio' in node_type:
            node.parm('loadfromdisk').set(True)
            node.parm('file').set(cache_path)
            count += 1
    if count == 0:
        hou.ui.displayMessage('进入需要设置缓存节点的层级下')
    else:
        mess(count)

把以上代码放在工具架,然后编辑此工具的键盘快捷键即可
