I'm currently wrangling a complex OBJ+MTL (~16 MB) import via free PMX Editor from an MMD (PMX) freebie found on DA. It, in turn, had been ripped by 'NanaCookie' from another format.

Set is a very nice 'BeefBowl' cafe, Japanese style. Detailed mesh, lovely textures. Imports to Poser at ~4.5% original scale, auto-loads textures. Must lower to ground manually. Looks really, really good.

I need to find and set the glass doors and windows to mostly-transparent, the many ceiling luminaires to 'super ambient'.  And, perhaps, re-do the menus / posters. Unfortunately, the original rip renamed the model's PMX materials to 'Maps( 0 ~~ nnn)'. 800+ of them.

As you may imagine, PP_11.3's material room is not happy.

First, it lists all the materials as mo, m1, m10, m100, m101 etc. There seems no page-down, so verrrry lonnng scroll to eg m418, the first of first group of luminaires, identified by searching MTL with eg Notepad. Then, that done, Material Room starts again at m1. [ Expletives redacted...]

The next group of luminaires commences ~ m779...

Is there a way to hop from an 'opened' material to next/previous material, or directly to material of given name, eg m419 ?

Is there a 'search' option within Poser to list an object's materials with their 'called' textures, so I can reverse-engineer ?

Plan_B is to hack the MTL, set glazing transparency, and those luminaires to super-ambient.

Hmm: I'd better check if Poser 'traps' imported OBJ+MTL ambience settings >1 as 'invalid'...
