The custom Bronto class in this mod is using the same DinoNameTag (Bronto) so I think it should work fine as is. Let us know if it doesn't though, I might need to change the Dino Name Tag for every dino >.<

DinoSpawnWeightMultipliers=(DinoNameTag="Bronto_Character_BP_AllColors_C",SpawnWeightMultiplier=0.6,OverrideSpawnLimitPercentage=True,SpawnLimitPercentage=0.1)
DinoSpawnWeightMultipliers=(DinoNameTag="Bronto",SpawnWeightMultiplier=0.6,OverrideSpawnLimitPercentage=True,SpawnLimitPercentage=0.1)
DinoSpawnWeightMultipliers=(DinoNameTag="Sauropod_Character_BP_C",SpawnWeightMultiplier=0.6,OverrideSpawnLimitPercentage=True,SpawnLimitPercentage=0.1)
DinoSpawnWeightMultipliers=(DinoNameTag="Sauropod_Character_BP_AllColors_C",SpawnWeightMultiplier=0.6,OverrideSpawnLimitPercentage=True,SpawnLimitPercentage=0.1)

My file is packed lol, it's not just brontos I've done this for >_>
I don't think 0.1 does much as a limiter but I'm pretty sure 0.6 decreases their spawns a lot, from what I can see, before I added the mod I feel like there was way less of all the dinos I had limited.

I feel like there's something wrong with spawning when using this mod but I can't really see what. Before I put this mod on there was way less Quetz. Now they spawn at almost all the places I expect to see them all the time, 2 or 3 times more frequently than before.

Quetz
Quetz_Character_BP_AllColors_C

I'm using 2 lines for these too just in case and it just doesn't seem to have any affect.

I'm pretty convinced now, I've been paying quite a lot of attention to spawns today and there's no way any of the weight multipliers I set are working.

This is all the weight multipliers I have set: http://pastebin.com/pxDrPxrM
I know it's a mess, I tried to cover all the options.

There was barely any brontos before I added this mod, now there's loads again.

@Chaos - I'll have to look into it, give me a couple of days to test.

Ok thank you, I appreciate your efforts! ^^
