Hi there @NailV123

I’d recommend this thread here How to update SwarmAgent.exe.config? I hope that helps!

[NailV123]

Okay I’ll try

I created a cache folder and selected it by default in Swarm and everything worked

I see. Do you run an NVIDIA Card by chance? (GPU)

[NailV123]

No, I have it from manufacturers AMD (Amd Radeon Rx 5500 Rt (8GB))

[FrostyJas]

Do you run anything like ROCm, GPUOpen, or Adrenalin? I was going to recommend trying resetting your GPU settings to global default(Or the AMD equiv. I’m used to NVIDIA CP) Also, try removing any ‘Saved’ or ‘Intermediate’ folders in your project folders. Especially if it’s only one of the levels causing this.

[NailV123]

I have AMD and downloaded adrenalin
And where should the intermediate and temporary folders be?

[NailV123]

Hello we managed to solve the problem by creating the cache folder that it asks for and then using SwarmAgent to set this folder as the default for the cache

[FrostyJas]

Ah, right on! Well, I’m glad that you got it working!

[NailV123]

Hi @FrostyJas !

Thank you, good luck!

[FrostyJas]

Same to you. Have a good week!
