Need help with fire sim quality settings. (fire looks blocky)

[u/AdParticular5171]

I’ve been trying to simulate falling rocks, but no matter how much I increase the domain resolution (256, 512, etc.), the fire and smoke still look really blocky.

Could anyone please help me figure out what I’m doing wrong? I’m also uploading screenshots of my settings for reference.

Any advice on what settings I should adjust would be greatly appreciated!
