Hi there,
You could try to edit the difficulty value in your TestGameMode. If you put it on e.g. Difficulty value min 1, value max 3 you’ll get random creatures from levels 1 - 90 (assuming you diddn’t alter the base level of the dino BP’s).
This mean that if you want to achieve 240 as max level, you’ll need to set your difficulty value max to 8.
If you want your creatures to spawn with a higher base level, make sure you’ll edit the value min to the amount;
1 (lowest level that can spawn) x difficulty value = new minimal level
Make sure you set the “Difficulty Value” at just 1.0.
I’ve tested it and this does the job! Hope this is the answer for you as well.
