Combine multiple textures in one decal?

Hello fellow devs,
does anyone know how to combine multiple textures in one decal?
Atm I have a decal with a certain position and a certain size, which needs to stay that way.
It contains a satellite image which I plan to use as reference for later world design.
Now I read that the texture engine limit is 8192x8192.
My question is now, if it is possible to have multiple 8k textures which combined fill the inside of the decal?
I am basically looking for a way to increase the “decal resolution” by combining multiple 8k textures instead of a single one.
Because due to the vast size of the decal, with one single 8k texture I am having a hard time.
Also, I am aware that having more decals would fix the problem.
But the decal is georeferenced, and I have not found a way to “split” the decals and still place them accurately.
Also, the decal and the multiple textures are not going to end up in the final game, so performance is irrelevant.
It would be great if someone had an Idea how to solve this :slight_smile:
Thanks

You could replace the decal with a plane mesh, and then texture the plane using a UDIM. A UDIM is designed to map extremely high resolution textures to objects. This will allow you to split the texture into smaller parts but still map them to the object in full detail. It’s commonly used in film quality assets to get the extreme texture detail needed for photorealism on the big screen.

Thank you for your reply :slight_smile:
Yes, I thought about UDIMs but it only works with meshes.
My decal goes on top of a landscape, for reference purposes.
It yould be very useful to be able to have some similar functionality like UDIMs for decals.
I have now managed to import a 16k texture. Source would be 96k :sweat_smile:
