@Henry_Boutet_de_Monv have you explored all files in the Leaves folder? from your screenshot it looks like the picture of the leaf is inside the “Single” folder.
Lands installer does not distribute all texture files used to create the plants. However, since texture files are embedded into the .ArTree file, you can extract them. Just right-click on the image and select “Save Bitmap to File”:
Hi,
Does the texture look changed in the Plant Editor? If so, please make sure to update the species. To do this, select it from the Selection List in the Edit Panel and click the “Update” button that will appear on the right. This will update the block for this plant.
If the issue persists or is related to the editor, could you please send us both the .3dm file and the .ArTree file you are using?
