After working with the MRI library, i’ve contacted him since i wanted to add material chunk support to its library. The email he sent me, had a link to Swizle-Studios where can be found a new version of his library with what i have asked for and a new and updated version of the documentation. Below you will find a link  to a new version of MRI-V3DS library for processing along with an updated version of one of my examples, v4. Documentation is also included in the zip file

Homepage | Get the newest version here.

new version includes all the old v4 sample did with some minor changes:
. added a materials and textures pool where i put all the data. then i use the material id to fetch for the correct material&texture.
. added a “color_only_no_texture” shader for any models that dont have textures or simply cant load them.

NOTE! every mesh must have a material associated to it. this examples dont support default materials. but you can easily handle that for yourself in you really want it.

enjoy.
