How to get the surface normal of another object

[HSDSZ]

In eevee, this could be done via geometry node (saving normal in geometry attribute then get it back shader node)
In malt, is there any workaround?

Actually, what I want is a stylized shaded tree.

Actually, what i want is a stylized shaded tree (left), but useing the right geometry normal for the NPR diffuse normal socket

With anoter geometry normal, the tree will get a general diffuse gradient instead of each leaf having a separted one

Here is a demo using the normal of another geometry

You can use geometry nodes as well with vertex colors.
Just keep in mind that only Face Corner Color Attributes are supported.

Is this a bug? malt vertex color is not working

in eevee, vertex color working correctly

in malt

here is the blend file
vertex color.zip

It looks like a bug (this used to work fine), but in Blender itself.
You can check that applying the geometry nodes modifier deletes the Color Attribute.
It looks like the same is happening with the mesh that Malt receives from Blender.

Ok, it's not a bug. You have to ensure that your output is set to Face Corner > Color:

oh, i see. I also need the change the face corner color in geometry node not only in the right panel
