Baked textures are transparent

So I want to migrate my assets to ue5 and I decided to bake the textures. The model is the ground of my scene which is considerably large with several material slots. I decided to bake all of it to a single image but the bake keeps aborting, and giving me a blank (transparent) image. Since it’s a very large model, I need a very high resolution image so I set the image textures to have a 12k resolution.

How I’m baking.

  1. Created an image textures and made a new image and saved it.
  2. Copied and pasted the image textures to all the material slots of the model and ensured that they were the active items
  3. UV unwrapped the model.
  4. Bake settings: turned off direct and indirect under the influence section and selected diffuser under the bake type.
  5. In the performance tab of the render properties, I disabled using tiles and under render samples, I set it to 100.
  6. Then I clicked bake

After a minute or two, it hits 1% and just aborts, leaving a blank image.
I don’t know if I did something wrong or if there’s another workflow I can adopt.
Thanks

System config:
Intel i7 10th gen @ 2.6 ghz base speed
16 gigs of ram
Nvidia rtx 2060 6gb

Just follow one of the courses lectures with baking in it.

Do you have a tool to see your internal memory consumption (CPU, GPU)?
Run this tool and see if your setup requires too much hardware.

Also, how you’ve configured the materials used is also a factor in how Blender performs.

  • How does it work when you are using a smaller bitmap size as 12K. try 800x600 as a starter.
  • Turn on the Blender INFO panel and see if Blender generated some internal state messages.
