accessing dForce surface values by script [solved]

meipe

When you add a dForce modfier to a character, several simulation parameters are added to it and can be edited in the surfaces tab.

Is there a way to access them by script? If I iterate the property list of the material's shape I can find everything, except them...

Have a look at this sample script http://docs.daz3d.com/doku.php/public/software/dazstudio/4/referenceguide/scripting/api_reference/samples/properties/material_properties/start

Short answer is: You need to access the DzDForceModifier.

Hope the following helps...

(Also attached as DzDForceModifier.txt in case the forum does not format the code correctly).

// May be useful to iterate the property lists of these classes:var Item = Scene.getPrimarySelection().getObject().getModifier(4042);             //  DzDForceModifiervar Item = Scene.getPrimarySelection().getWeightMapHandler().getWeightGroup(0);   //  DzDForceModifierWeightGroupvar Item = Scene.getPrimarySelection().getWeightMapHandler();                     //  DzDForceModifierWeightHandlervar Item = Scene.getPrimarySelection().getObject().getCurrentShape()             .findSimulationSettingsProvider( Scene.getPrimarySelection()             .getObject().getCurrentShape().getSimulationProviderNames()[0] );    //  DzDForceSettingsProvidervar Item = App.getSimulationMgr().getSimulationEngine( 0 );                       //  DzDForceEnginevar Item = App.getSimulationMgr().getSimulationElementObjects()[0];

Thank you! Richard's sample script is easy to use.

Just set, for example at line 236

var sPropertyName = "Contraction-Expansion Ratio";

 

and add a line of code at the end of the script to edit the property value:

 

oProperty.setValue(0.66);

 

I wasn't able to use praxis's approach, but I suppose t may work.

Not my script, but I'm glad it worked.
