Frequently Asked Questions

What is the PF2B cache?

The PF2B cache consists of thumbnails and JSON files that store information about the plants and presets, such as plant height, polygon count, and other details. It is used to display the plants and presets inside the gallery, allowing you to browse them easily within the addon.

The cache that is shipped with PF2B includes a total of 23,678 thumbnails (491 plant thumbnails and 23,187 preset thumbnails) and is approximately 309 MB in size. It covers all plants and presets from both the PlantCatalog and PlantFactory libraries.

For more details on setting up the cache, see the First Time Use & Importing Cache section. Additional configuration options can be found in the Preferences page.

Check that your 3D View is large enough, as the gallery size depends on it. If you have the view split (for example, with the Shader Editor), it may cause the gallery to appear smaller.

What Normal Map format does PlantFactory use?

PlantFactory uses the OpenGL normal map format, which is the same as the one used in Blender, so no conversion is required.

PlantFactory starts, but nothing happens, and no plant is imported into Blender

Addon Location

Check that the "Preview" window under "Display" in PlantFactory is enabled, as shown in the screenshot here:

I receive a "Are you sure you want to abort the export" popup during import

Preferences - Misc
This is usually caused by PlantFactory not having enough time to load the geometry of the plant before the export is attempted. Try adjusting the Geometry Load Buffer under preferences to resolve this issue. As an alternative workaround, in cases where this persists, hold down the "Escape" key for 2-3 seconds to make the popup disappear.

My plant appears too dark and some textures show black backgrounds

This issue is often caused by the Transparency Bounces setting in Blender being set too low. Increasing its value should help ensure proper light distribution and eliminate the dark areas.

Example

Transparency light bounce example Transparency light bounce example

  1. Navigate to the Render Properties tab.
  2. Scroll down to the Light Paths section.
  3. Locate the Transparency Bounces setting.
  4. Increase the value for Transparency Bounces.
  5. Re-render your scene to see if the issue is resolved.

What is the difference between a Backlight texture and a Translucency texture?

There is no difference, both refer to the same type of texture used to simulate light passing through thin surfaces like leaves.

I want to create my own plants. What should I keep in mind?

To ensure materials are set up correctly when importing them with PF2B, name your materials properly inside PlantFactory. Specifically, include a keyword that indicates the type of material they represent. Recognized keywords include leaf, bark, flower, fruit, and other relevant terms. This allows the addon to correctly identify and process materials during import.

For more details, check the 'Automated Setup' section in PF2B: Under the Hood.

Tip

Check out the Community section for guides and resources on getting started with creating your own plants.

My plant Materials looks off. What can I do?

The translucency looks off

This might be caused by a low-quality translucency map that is not normalized and is either too bright or too dark, causing too much or too little translucency for the plant. If this is the case, you can:

  1. If you want to disable the translucency texture altogether, you can do this easily via the Post Processing panel by selecting the plant, editing the leaf material, and disabling it there.
  2. Manually go into the material and adjust the texture by, for example, adding a Color Ramp or a Map Range node between the texture and the shader and adjusting the brightness until the translucency looks correct.

If you believe the translucency texture setup is incorrect, please get in touch with me and provide the plant details, and I'll investigate further.

Tip

You can also disable the translucency texture import by unchecking the Import Translucency Map option under the import settings to use a static translucency value instead.

The normals look off

Troubleshoot - Clear Custom Split Normals

Try clearing Custom Split Normals to see if this helps. This can be done easily by selecting the plant and navigating to Properties Panel > Data > Geometry Data > Clear Custom Split Normals Data, as shown in the image:

If the issue persists, please get in touch with me and provide the plant details, and I'll investigate further.

Other Textures Look off / Missing Textures / Wrong Textures

This might be caused by inconsistent texture names, as mentioned under PF2B: Under the Hood. Please try to troubleshoot the issue using the Troubleshoot Guide: Missing or Incorrect Textures first to pinpoint the problem.

If there are textures that are not connected or are incorrectly connected for a specific plant, please get in touch with me and provide the plant details, such as the name of the plant and the preset used, and I'll investigate further.

Plant Geometry looks incorrect. What can I do?

Please get in touch with me and provide the plant details, and I'll investigate further.

There are missing plants / empty thumbnails shown when browsing plants

Please run both the Re-Index Plants and Reload Thumbnails tools found in Preferences > Misc.

Why does my my plants show 'No Presets'?

This issue is likely caused by a missing or incomplete Preset cache.

  • If this occurs with plants from the PlantCatalog & PlantFactory libraries, you can download and install the cache as described here.
  • If this affects other plants, you can regenerate the cache using the tools available in Preferences > Plant Library.

Note: Not all plants in the 'PlantFactory library' have presets available.
