just thought I’d say that if you cant find bloom (or any of the other settings), they have been moved since Blender 4.2. You now have to go into Compositing and add it manually. Here’s how to do that!
I recommend you add a camera and render beforehand, so enter Layout (you’re probably in it, just check at the top) and press Shift+A and search “Camera”, it should be the first option.
Position the camera however you like. The black arrow shows the top and the flat, rectangular face should be the front. Once you’re ready, press f12 to render. This may lag or take some time depending on your device or what else there is to render.
Once you’ve rendered (or if you’ve skipped it), enter the “compositing” tab. It should be at the top next to “Rendering” and “Geomentry Nodes”, though if you’ve moved it you should know where it is.
Once you’re in, make sure the “Backdrop” property in the top right is blue, if it isn’t just click it.
Turn on “Use Nodes” in the top left, as it is off by default. There should be two default nodes, if you don’t see this, press Home on your keyboard or click “view” in the top left and click “Frame All”.
Now, press Shift+A and search “Viewer”. Connect the “Render Layers” Node to the Viewer (it should be connected to Composite too.) You should now see something similar to this:
if you don’t, try searching for the names shown above each Node and connect them as shown in the image.
Now, press Shift+A, and search “Glare”, or go to Add>Filter>Glare. Drag the “Glare” Node over the line connecting “Render Layers” to “Viewer”, once the line turns white, release it and it should automatically join. If it doesn’t, you can do this manually by disconnecting the nodes and reconnecting them, placing the “Glare” between them. You should now have something similar to this:
This (should) be enough for you, as it was for me, however if it isn’t you can turn on Raytracing, which replaced Ambient Occlusion and Screen Space Reflections in Blender 4.2.
Sorry if this tutorial sucks I don’t do this sorta thing often
