Hi everyone, hope you have been doing well. This is my first time posting here.
These are the final products.
These renders were all made using Cycles instead of Eevee.
The first two images have some sort of artifacting/pixelization happening in the darker parts of the image, although denoising was applied (I don’t know why this happened, maybe the Noise Threshold was too high).
The bloom effect was achieved by using compositing, adding a Glare node to the pipeline and setting it to Fog Glow instead of Streaks. The Denoiser node was added because in the tutorial, that I saw, they used that node, but it is not necessary for the bloom effect. You can see the pipeline in the image. Don’t forget to tick the Use Nodes options, this won’t work if you don’t do it (it’s highlighted in the image).
The stars in the background were achieved by using a Noise Filter and Color Ramp node. The scale on the Noise Filter needs to be a big number in so that it can appear like stars. The Color Ramp is used to isolate the lighter parts of the noise filter and “hide” the darker parts, making them appear like stars.
If someone would like to teach me another more efficient/correct way to achieve what was previously stated, I would highly appreciate it.
I apologize, if something is not so clear or something is not syntactically correct as English is not my first language.
Thank you for viewing this post, and have a great day.
