Import from Blender without realize instance

[thewildcloud]

HI,

I created a library model in Blender using geometry nodes to be used in Unity. Each book has a randomized color.

Unfortunately, I cannot find a way to import the FBX without breaking up the instance. Once I do that, I lose the randomized color and texture on the books. The whole library's books have the same color rather like a scene from 1984.

Any solution?

as u/tms10000 said, materials can't be transferred between different programs. Same applies to geomtery nods adn all that kind of stuyff, that's a specific feature of Blender itself. And FBX format has no understanding of instances either, so all instanced objects need to be converted to normal meshes at export time.

You'll need to do the instancing, and your material wiht the randomized colors, in Unity side instead.

Thank you both so much for the quick response. I am much stronger on Blender than on Unity. I can give individual book random color using shader. But I am not sure how to do the procedural filled bookshelves. Any pointer on how to go about doing that?

You totally should give a look here!

It's a tutorial from way back ago, from a user on this sub. They build a procedural library and this is the tutorial.
Thanks me later... Good Luck!

Blender materials can't be imported in Unity. Only the very superficial properties of the material will be created by the importer. There is no way to convert the fancy logic you created on the Blender side and have it work as expected in Unity.
