There is already one. It's called "Crowbar".

I know and that's why I was "just saying". But if there would be this feature there is probably no need for Crowbar when we have all in one. Huh? And, why is there model compiler if we have something called Crowbar?

Because the Blender Source Tools are for creating models, which involves compiling them.

Modifying models isn't rare. Atleast in my case I rather decompile model and make these few changes than create whole new model for that. So decompiling kinda might be part of that model creation

If you want to make changes to an existing model, just decompile it.

But... that's exactly why I wish there would be decompiler in Blender if there is compiler as well! Now I have to own Crowbar for only decompiling when I can do everything else in Blender. Ugh

Only one missing feature of a full complete tool

It disturbs a lot

If you're talking about Crowbar... No, it's a model tweaking tool, not a modelling tool.
If you're talking about the Blender Souce Tools... No, it's a model making tool, not a model tweaking tool.

Talking of Blender and Source Tools in it. Idea is to put modelling and tweaking in same

If you can't figure out decompiling a model in Crowbar, why not just say so? That'd be easier for us both.

Never said I can not use Crowbar. Don't you get the point?

Not really. What you want: A way to decompile models without using a model decompiler. That doesn't make sense.

Blender Source Tools can compile models even when it is for model creations and not called as compiler tool. *sigh* Just forget everything ok? XD

Model creation involves compiling models. Model creation does not involve decompiling models.
