3ds Max 云端渲染插件 - 完整 Python 解决方案

news 2025/7/23 5:44:02

背景

本地3ds Max设计完图之后，每次渲染都需要很长时间，极大的浪费时间，现在就需要一个方案解决如下痛点：

  1. 加速渲染、并自动存储；
  2. 全自动化；

解决方案

详细步骤

1.python代码

下面是一个完整的 Python 实现方案，包含一键上传、资源收集、打包上传、进度显示和菜单集成等所有功能。这个解决方案经过优化，可直接在 3ds Max 中运行。

安装与使用指南 

1. 安装依赖库

在 3ds Max 的 MAXScript 侦听器中运行以下命令安装依赖：

python.Execute "import subprocess; subprocess.call(['pip', 'install', 'requests'])"

2. 安装插件

  1. 将 cloud_render.py 保存到 3ds Max 脚本目录：

    C:\Program Files\Autodesk\3ds Max 202X\scripts\

  2. 创建启动脚本 init_cloud.ms 并保存到

C:\Program Files\Autodesk\3ds Max 202X\scripts\startup\

内容为：

python.ExecuteFile @"C:\Program Files\Autodesk\3ds Max 202X\scripts\cloud_render.py"

 

3. 使用插件

  1. 启动 3ds Max：

    • 插件将自动加载

    • 在 MAXScript 监听器中会看到初始化消息

  2. 访问菜单：

    • 转到顶部菜单：渲染(Rendering) → 一键上传到云

  3. 工作流程：

graph TD
A[点击菜单] --> B[显示进度对话框]
B --> C[收集场景资源]
C --> D[打包为ZIP]
D --> E[分块上传到云]
E --> F[显示结果]

        4. 配置选项

编辑 cloud_render.py 顶部的 CONFIG 部分：

CONFIG = {"server_url": "https://your-render-farm.com/api/upload",  # 实际API地址"username": "your_username",  # 云服务账号"password": "your_password",  # 云服务密码"temp_dir": "D:/temp/max_cloud",  # 建议改为SSD路径"chunk_size": 10 * 1024 * 1024,  # 大文件可增大到10MB"max_retries": 5  # 网络不稳定时可增加重试次数
}

功能亮点

1. 智能资源收集

  • 支持多种资源类型：

2. 高效打包系统

  • 增量压缩技术

  • 包含资源清单(manifest.json)：

    {"max_version": 25000,"scene_name": "car_rendering.max","renderer": "V-Ray","assets": [{"path": "D:/projects/textures/car_paint.jpg","size": 4587921,"modified": 1685091200,"hash": "a3f4c2...","type": "texture"}]
}

3. 可靠上传机制

  • 分块上传（支持大文件）

  • 自动重试机制

  • 进度实时显示

  • 取消支持
