Better Inf map editing with sketchup

Silver_Ibex · Feb 21, 2011

While chatting on IRC I saw this posted during a discussion of better optimizing of workflow in Ued with external modeling programs, it is a handy ruby script for exporting multiple brushes out of Ued so they can be edited in Sketchup with less work then exporting them one at a time.

To make a new Ruby file, do the following
In your Google Sketchup plugins folder, make a new txt file and rename it “Ued_T3D_Multi-Brush_Import.rb”
And then copy and past into it the code below and save the file.

Code:

#===========================================================================================
# Ued_T3D_Multi-Brush_Import.rb                                                            
#===========================================================================================
# This script lets Ued mappers build better custom complex  
# brushes for their maps with the help of Sketchup.
# 
# Place this file in Sketchup "plugins" folder.
#
#
#
# To use follow these mapping steps. 
# 
# 1. Load your map in Ued. 
# 
# 2. Select the brushes you want to export in your map then 
#    invert the selection and delete everything else in the map.
# 
# 3. To make the exported file smaller/faster you can rebuild 
#    the paths (this is to clear the paths out so they don’t get 
#    exported as part of the .t3d file).
# 
# 4. Select all brushes and chose “transform permanently” (the 
#    Sketchup importer does not see any temporary transform 
#    scaling and rotations).
# 
# 5. You can rebuild the geometry and fix or align textures now 
#    if you want.     
# 
# 6. Export the map as a .t3d file.
# 
# 7. In Sketchup, chose import file type "Ued T3D Level File",
#    and you should then be able to open your .t3d file.
# 
# 8. Have fun :)  
# 
# 9. to get the stuff back out of Sketchup and back into Ued, 
#    use Google Sketchup T3D/PSK Exporter for UT3/UT2K4/UT2K3 
#    - HSKP2UNR found at

After all Inigo weapon releases, a Silver_Ibex map would breath a lil life to INF´s community... a map or that HUMVEE driveable in INF that could save a lot of COOP time or even better, a huuuge map, with your photorealistc landscape technique and scripted Humvees to transport the players around multiple objectives (an EAS map for sure...)

OK, just excuse my daydreaming, but I was aching to ask ya that ;D

Thought I should post a pic showing what imported and edited brushes look like in Sketchup, since they are imported as separate objects they can be moved around and adjusted in Sketchup, unlike HSKP2UNR which merges brushes on import into one object.

Sketchup is Free, and is extremely powerful for fast editing of brushes made in Ued, the plug-in allows multiple brushes to be imported into Sketchup and then selectively joined or split at will (use the “Explode” and “Make Group” options), brush faces can be modified with far more freedom then standard Ued, you can literally draw new features on the faces of a brush in Sketchup.

In Sketchup the grid scale options need set up to match an external editor like is talked about the page of this article here
http://www.maximumpc.com/article/howtos/howto_make_left_4_dead_map_using_google_sketchup?page=0,4

The one small problem I have with the plug-in is faces on imported brushes sometimes face the wrong way and some may need flipped before you export them back out of Sketchup. This is not a real big deal, just something to watch out for.

For a fast start, the Google Sketchup tutorial videos are a must watch.
