Greetings. I am trying to compile a model for Garry’s Mod with over 32 materials so I had to use cra0kalo’s StudioMDL for it. The problem is that the model won’t appear in the game with face flexes added with the following console error:

```
Model uses STRIP_IS_QUADLIST_REG - will crash in this engine - so not loading!
```

Reducing the number of materials is not an option, so what do I have to do to get both materials and face flexes working? They work flawlessly when separated, but that’s not what I need.

Here’s a part of the QC with merged facerules and standardflex:

```
