Hi
is there a way to export a group of objects (a group not a selection) with maxscript using:
CProxy.ProxyFp.fromScene (CProxy()) “groupnode” @“D:\myproxy1111111.cgeo”
much appreciated
this will work for you.
/*
================================================================================
CORONA TEAM PROXY EXPORTER
================================================================================
DESCRIPTION:
Converts selected geometry or groups into Corona Proxy (.cgeo) files.
Works with single objects, multiple objects, and grouped objects.
Automatically handles closed groups by opening them temporarily.
HOW TO USE:
1. SAVE YOUR FILE FIRST! This script modifies your scene.
2. Select the object(s) or group you want to convert to proxy
3. Run this script (drag into viewport or run from MAXScript menu)
4. Click "..." to choose where to save the .cgeo file
5. Set options:
- Delete original: Removes source geometry after export
- Collapse to single proxy: Combines all selected into one proxy
- Keep in group: Places new proxy inside the original group
6. Click "Export to Proxy"
OPTIONS:
- Delete original: Check to remove the original objects after proxy creation
- Collapse to single proxy: Merges all geometry into one proxy file
- Keep in group: If source was in a group, proxy stays in that group
FEATURES:
- Auto-refreshes when selection changes
- Works with nested groups
- Preserves object positions
- Names proxy as "originalname_proxy"
REQUIREMENTS:
- Corona installed
- 3ds Max 2020 or newer recommended
