For anyone wondering, the texture palette is missing from the downloads. The Colorsheet texture from the "NatureForge: Stylized Woodland Forest" pack works perfectly for this whole pack.
Thanks for catching that and for taking the initiative to look into it — much appreciated. For the sake of consistency I'll hook up the correct texture on my end and re-export the project, so everything lines up properly. Thanks again for supporting the pack and for keeping an eye on my work.
