Call of Duty 5: Dynamic Foliage
This tutorial will show how to create Dynamic Foliage in COD:WAW. Credits for Tutorial and Script goes to Zweimann
Intro
By Zweimann
This is an easy way to have Dynamic Foliage in your custom map. Only 2 Steps. This code works and needs no mod, so your map runs dynamic foliage as a standalone block.
This is what you get:
Preparation and Radiant
- Change your misc_models (Trees and Palms, Foliage and grass) to script_models.
- Choose between 3 different targetnames for them (can be any of them but changes must be reflected in the script in next Step):
Trees and palms:
targetname: dyn_trees
Big Foliage:
targetname: dyn_foliage
Grass and tiny foliage:
targetname: dyn_grass
TIPS
It can be a long task to change all your misc_models into script_model and add the targetname so here is one way to do it quicker:
Make a backup of your .MAP files before starting this Tutorial in case something goes wrong!
- Select one of the model you wish to have dynamic - for this example lets say the model is called foliage_cod5_tallgrass10a
- Bring up the Entity properties using n
- Highlight the K/V Model/foliage_cod5_tallgrass10a
- Close the Entity properties by pressing n again
- Now go to Selection > Select by Key/Value (or use shorcut SHIFT-CRTL-F):
- After you click you will see that the Key Model and Value foliage_cod5_tallgrass10a will be already filled in, click OK
- This will now select all the other Model called foliage_cod5_tallgrass10a in the level
- Bring up the Entity properties using n
- Now you can change misc_model Key to script_model (highlight it first then edit)
- After this you can add the new K/V:
Key: Targetname Value: Dyn_foliage
Script_models do not support Modelscale!! Make sure to reset to 1 or remove the modelscale K/V if any and replace the models accordingly on ground.
- You can now press Enter to complete and keep going with other models
- Remember to keep an eye on the number of script_model using M:
Scripting
- Create a new file in raw/maps/mp/ called _dynamic_foliage.gsc
- Open it with Notepad and copy/paste the following script:

- Save the file, now open your Main Map GSC File and just before the final } add this line:
maps\mp\_dynamic_foliage::initdfs();
- Save the file
Zone File
- Add the following line to your Zone File:
rawfile,maps/mp/_dynamic_foliage.gsc
- Enjoy a new CODWAW Experience!
Limitations
Just like Spawns the script_models are Entities and therefore have a limit - most likely to be 1024. The maximum number of Script_models so far tested is 576.
You can check the number of entities you have in a level by hitting M when in Radiant.
