@smokey8808, can you load texture manually into a textures browser? Do you see a texture there once you load it? Note, textures browser shows textures in a current group (the one you pick in top-left corner), so you should pick "All textures" there to see all textures loaded.
I can add textures manually yes. But importing a .yft model shows textured model while texture browser remains empty. I have not specified a .ytd archive to load upon selecting a .yft to import, as pinned guide explains that specifing an external search path with textures should work alright.
Perhaps there is a misconception on how importing works in zm3 compared to zm2. I am used to exporting textures from a .ytd file to an external folder, add it to search path and import .yft file. This gives me a textured model in zm3 but the texture browser is empty. If i save such a scene and open it again, the model is untextured and the browser is still empty.
