HPL Editor

[CarnivorousJelly]

Depends what you're calling a pain in the ass about it...

Because you're right... if you're talking about the lack of coloured spec maps, various bugs and crashes, the way normals are used in-game, importing models and animations you created yourself (Traggey or Robo could give more examples for this kind of PITA).

If you're complaining because it's hard or confusing, you obviously haven't spent a ton of time working with the Level Editor. Definitely one of the most simple configurations I've seen. Comparing it to, say, UE4 would be like comparing MSPaint to Photoshop.

Personally, I like HPL2. It's like playing with lego or knex for me
