When you say your custom stuff doesn't work, could you elaborate more?
MOST of my custom stuff works fine, with a few exceptions, and most can be fixed by a few fpe or texture adjustments.
For characters:
For best results characters need 3 textures now. First is a diffuse texture, if you want some transparent parts then use an alpha channel in the diffuse texture, otherwise no alpha in the diffuse. Second, they need a normal map to look decent, it doesn't HAVE to be anything fancy, just flood an image with RGB values of 128,128,255 respectively, and you will get much better ligthing than not using one at all. NO alpha channel in the normal map! Lastly they need a specular map, and this one MUST have an alpha channel, white in the alpha is used for self illumination (like lights on a character), but it MUST have an alpha channel, just fill the alpha with black if you don't need self-illumination.
All characters use Darkai now, at least for now you can't use old fpi commands from X9.
Instancing uses a specific naming structure, look at the scifi character folder for examples, and make sure your naming system for your own stuff isn't interfering with it.
For entities:
The scale property doens't work at least for now, export your models at the size they must appear in game.
The animate=x fpi command doesn't seem to work for now either (for entities).
Some doors I've made needed some adjustments in the fps file to line up right, adjusting the offy value fixed this.
That's what I've found so far, and like I said most things I could fix, except for a few things I made back when I didn't know what I was doing.
