Cannot confirm this, as all paths are correct are the commands work fine for me in Singleplayer and on Dedicated. Is the Mod installed correctly?
It just works if the Scorched Earth DLC is installed, as the Mod references most Core Wyvern files.

Nevermind, you don't have to have SE installed for it :D
This just leaves the question if the Mod was installed correctly for you.

i think it is a invalid pathway

yeah its a invailid class path

As i said: For me, and my friends, both spawn codes work just fine. I have no other explaination than that there's something wrong on your end :D

try testing in both single-player and multi-player. I usually found issues that way when making my own mod. But that's very strange that it's not working...

Also, in a bug report, please post your mod load order to help the mod dev :)

Oh, i think i see what the problem is. make sure to replace the spawn codes with the reference path. Right click on the bp and then "copy reference" shold be at the bottom. then place it in here:

cheat spawndino "[here]" 30 200 0 0

might or might not be the solution. but worth a shot.

You might have to put "Blueprint'" before the actual code chain

can someone give me the code?
pls?

blueprint code please

I suggest try 'admincheat summon VoidWyvern_Character_BP_C', but do PlayersOnly first in case the dino spawns as a wild (Most likely will). Sometime typing admincheat summon tends to spawn the creature better than GMsummoning. And this is what I got for blueprints, but don't expect the blueprint code to work,

"Blueprint'/Game/Mods/VoidWyvern/Creature/VoidWyvern_Character_BP.VoidWyvern_Character_BP '"
