Applies to Gaia Pro Version:
When applying the CTS profile for the Coniferous Forest biome, the order / amount of textures between the CTS Profile and the texture spawner is different.
The texture spawning settings for this biome were not updated to match the CTS Profile correctly.
Please download and install the patch package from the link below. It contains a fixed version of the texture spawner for the Coniferous forest biome. You can install the file by double clicking on it while your Unity editor with the Gaia Pro project is open, or by selecting "Assets > Import Package > Custom Package..." from the top menu in the Unity editor.
