Blender material normal map into Akeytsu trouble

kanga

Hi

Blender 3.0 Win10

Just textured my character in TB and trying to get it into Akeytsu from Blender. Finally got the texture included with the fbx but it seems only single nodes are recognised. The normal map needs a bitmap and a normal map node to work. I have looked everywhere and there is some talk of blender render materials that don't use nodes. Do any of you know anything about such a material, or even better, what works from Blender to Akeytsu.

Thanks in advance.
