# Preferences > Configuring preferences and settings in the Asset Transformer SDK. Use the [core.setModuleProperty](/asset-transformer-sdk/2026.4/api/python/core_functions.md#setmoduleproperty) function to set preferences. ```python title="Python" pxz.core.setModuleProperty("Core", "ThreadCount", "20") ``` ```csharp title="C#" pxz.Core.SetModuleProperty("Core", "ThreadCount", "20"); ``` The following snippet can help getting an overview of all module properties, their type and value. ```python title="Python" for m in pxz.core.getModules(): if m.name == "Unity" or m.name == "Raytrace": continue print(m.name) for prop in pxz.core.listModuleProperties(m.name): print(" " + prop.name + " (" + str(pxz.core.PropertyType(prop.type)) + ") = " + str(prop.value)) ``` ```csharp title="C#" foreach (ModuleDesc m in Core.GetModules().list) { System.Console.WriteLine(m.name); if (m.name == "Unity" || m.name == "Raytrace") continue; foreach (PropertyInfo prop in Core.ListModuleProperties(m.name).list) { System.Console.WriteLine(" " + prop.name + " (" + prop.type + ") = " + prop.value); } } ``` > **Tip:** > > Use [core.listModuleProperties](/asset-transformer-sdk/2026.4/api/python/core_functions.md#listmoduleproperties) to list the properties of a module. | Module | Property | Type | Default Value | Description | | -------- | -------------------------------------------------- | --------------------------------------------------------------------------------------- | -------------------------------------- | -------------------------------------------------------------------------------------------------------------------- | | Algo | DisableGPUAlgorithms | [Boolean](/asset-transformer-sdk/2026.4/api/python/core_types.md#boolean) | `False` | | | CAD | UnitLength | [Distance](/asset-transformer-sdk/2026.4/api/python/geom_types.md#distance) | `0.02` | | | CAD | TangencyAngle | [Angle](/asset-transformer-sdk/2026.4/api/python/geom_types.md#angle) | `10` | | | CAD | CurvatureThreshold | [Real](/asset-transformer-sdk/2026.4/api/python/core_types.md#real) | `0.02` | | | CAD | CurvatureRatio | [Real](/asset-transformer-sdk/2026.4/api/python/core_types.md#real) | `0.5` | | | CAD | CurveMaxSplit | [Int](/asset-transformer-sdk/2026.4/api/python/core_types.md#int) | `10000` | | | CAD | SurfaceMaxSplit | [Int](/asset-transformer-sdk/2026.4/api/python/core_types.md#int) | `1500000` | | | CAD | FaceBuilderDebugViewerEnabled | [Boolean](/asset-transformer-sdk/2026.4/api/python/core_types.md#boolean) | `False` | | | CAD | FacesDebugViewerEnabled | [Boolean](/asset-transformer-sdk/2026.4/api/python/core_types.md#boolean) | `False` | | | Core | ThreadCount | [Int](/asset-transformer-sdk/2026.4/api/python/core_types.md#int) | `10` | | | Core | EnableDebugLog | [Boolean](/asset-transformer-sdk/2026.4/api/python/core_types.md#boolean) | `False` | Enable advanced debug log generation.
