Adjust spawn rates?

[Kamakazee Monkey]

Looking for some help adjusting the spawn rates for specific dinos on my singleplayer game. For example If I wanted to reduce the spawn rate of Pteranodons by about 20% because they are absolutely everywhere and increase the spawn rate of Tapejaras by 20% so that they aren't so ridiculously rare what would I need to do?

You can in fact adjust spawn rates using ini, I learned how by seeing what was available on the wiki. https://ark.gamepedia.com/Server_Configuration#Creature_Spawn_related. I however dont know what default values are for spawn percentages of creatures but i'm sure that can be searched for.

I've tried using the information from the wiki but I don't understand it all well enough to do it correctly. Every time I've tried to adjust somethings spawn rate I either make it take over the world or go extinct.

The spawning works partially by RNG.
Within a spawn container each time a roll for a new dino is made it is affected by the "entryweight". If that is below the max desired then the spawn will continue.

It sounds like what you want to do is change the max desired.
Also I am pretty sure that if you're overwriting spawn region settings you need to do so for EVERY dino that you want in that spawn container and not just one.

IMO it's a bit of effort for something so minor in your OP.

Have you checked this:

DinoCountMultiplier=1.000000 for example DinoCountMultiplier=0.4000000 is 40% of what normal spawn rates would be but DinoCountMultiplier=2.000000 is 2x the amount you can type in that line in the gameusersettings.ini bit in your note pad under serversettings

Big credit to you for trying to help out in this thread, however I'm afraid it was written back in 2020.
