EDIT V2: Added new photos with camera settings and render settings.
Hi there this is my first ever post in this forum. I'm new to blender and proabably doing something stupid but I'm struggling to come up with a solution for my render and I can't just keep creeping through threads.
Basically I'm trying to render a fire simulation but it doesn't seem to want to come out right, it always seems a bit blurry. I tried turning off motion blur and depth of field and increased sub sampling and turned on branch path tracing. I've also tried increasing my sample rate to 1000 and increasing the overall ambient light, turned indirect clamping on and off, increasing resolution... Still nothing... I'm sure it's something simple I'm missing but I can figure it out please help!
