At this moment "NO" but very possible i think, I posted this Z archive thread releated to files and folders in MTX - http://dirttwister.com/smf/index.php?topic=462.0 inside you can find all the model,texture,collision files for bikes and models.
Yes we can replace items
as from my initial tests filenames are only resident source wise, i.e we can rename other files to files and they will stilll load as no data inside the "files" look for paths/names etc.
Image format *.tex (check Z archive thread) maybe somebody can make a nice little image reader ? TEX2dds and vica versa, i doubt whether it will be too long but just depends on peoples interest but int loks fairly open for us.
Ive uploaded a Tex,Col & Mesh file for a model here - http://www.3dactionplanet.com/reg/Mtx_Mototrax_Mesh_Tex_Col.rar mayeb any "tool developers" could look at these uncompressed files, Ive already spoken to oleg(zmodeller) about the mesh format and possible import/export but he has too much on his plate at the moment but im sure "Textures/Skinning" will be possible once this little Tex format is cracked.
