Clarisse Survival Kit

The Clarisse Survival Kit is a set of Python scripts I made to eliminate repetitive processes from Clarisse.

Asset Importers

  • Import a Megascans asset. Meshes will automatically have their materials assigned when imported as .obj. Alembic(.abc) files will be imported as references. 3D assets such as 3d models, plants & atlases will also have a shading rule created for them.
  • Import meshes(.abc/.obj) and generic textures such as Substance. Meshes will automatically have their material assigned and shading rules are created. You can specify which textures should be interpreted in which color space if needed. Custom rules can be added/modified in the file. TX or UDIM files will be converted to Streamed Maps.

Import Megascans Library

Import the whole library or specified categories. If you need individual assets use the Import Asset script. If you import 3D assets make sure you import them in a context that is currently not rendered inside your viewport. Otherwise it will try to render all objects.

Megascans Bridge Communication

Launch the Bridge listener from the shelf and send assets directly to Clarisse. Make sure the Command Port is running. You can enable the Command Port from the preferences. Keep it at the default port number of 55000. When exporting assets from Bridge to Clarisse make sure to select Custom as your application and keep the port at the default of 24981.

Since the Bridge communication script is running outside of Clarisse and decoupled from CSK I didn’t make these settings configurable. You can edit the python file if you need to customize the ports, but these settings will be overwritten once you install a new version.

Packing channels is not supported. Assets that are exported outside of the library will work fine.

Texture(s) to Triplanar

Converts the selected textures to triplanar.

Blur Selected Texture(s)

Blurs the selected texture with a custom radius.

Mix Multiple Surfaces

  • Creates a PhysicalBlend between one or more base surfaces and a cover surface(like dirt/snow). All selectors except displacement are instanced so you can manipulate multiple mixed surfaces at once. With this powerful script you can transform a whole scene into a snow covered one with ease.
  • Masking features:
    • Height blend: Mixes the materials based on Y elevation. Handy for shore lines.
    • Displacement blend: Checks which displacement map has higher elevation than the other. You can invert the selector or add both layers on top of each other.
    • Slope blend: Mixes two materials based on slope angle.
    • Triplanar blend: Uses triplanar mapping for the mask. By default the top facing(Y+) angle is masked.
    • Scope blend: A scope object is automatically created to quickly mask things out.
    • Occlusion blend: You can use Ambient Occlusion to blend the materials. Has a huge impact on performance when used with Displacement.
    • Fractal blend: If any other selectors are active the Fractal blend selector will be overlayed on top to break up the masking in the transition areas.

Add Surface(s) to Mix

Adds the selected surfaces to an existing mix.

Toggle Surface Complexity

Swaps out the selected material temporarily with a simple PhysicalDiffuse material. When you rerun the command on the selected PhysicalStandard material or its parent context it converts it back to the original state.

Moisten Surface

Adds a wet layer on top of the selected material. Several masking options are available.

Tint Surface

Adds a blend texture which can be used to colorize the selected surface so it matches better with other surfaces.

Generate Decimated Pointcloud on Geometry

Generates a GeometryPointCloud or GeometryPointUvSampler on the selected object. Has several masking options for decimating the point cloud.

Stream Toggle

Converts the selected Map Files to Streamed Map Files and vice versa. If the texture is single channel it will generate a reorder node for you. UDIM tokens are automatically added in the filename if they exist. Almost all settings are copied over.

Texture Converter

Convert images to tx or other formats and vice versa. TextureMapFiles will be converted to TextureStreamedMapFile when converting to .tx.

Reconvert Selected Textures

Scans the selected textures or child textures in the selected context for newer source files in the same directory. Source files that have a more recent date_modified timestamp get reconverted to the same extension of the selected texture maps.

Quick Blend

Select two or more items of type: Texture(any type), TextureNormalMap, Displacement, Physical Material(any Physical material) and your selection will be blended together with the appropiate blend or multiblend node.


Mask out selected blend nodes with common masking selectors. If nothing in the list is selected it will create just the masks.

Heightmap Wizard

Creates a displaced terrain from a heightmap. You can split the terrain in tiles or you can use premade tiles from applications such as World Creator and World Machine. Each terrain tile can have different quality settings to optimize speed and memory.
