Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

Short description of error
Order of connection to Join Geometry node affect on shader local space:
Exact steps for others to reproduce the error
a. Created shader with noise.
b. Create geometry node tree.
Object Infonode for represent second cube.Join Geometrynode, connectObject InfoandGroup Inputnodes inJoin Geometrynode input.Join Geometrynode.Expect: Local space of noise used only for one of joined objects and depend of connections order.
Original report:
Short description of error
The way how normals are rendered are affacted when I use a geometry node with delete and join.
Exact steps for others to reproduce the error
Setup:
Output without geometry node:
Output with geometry node:
The normals seems to have a different scale.
This is the follow up of #102189, which fixed the uv maps. These are working now as expected, seems to be a normal only issue.
Geonodes delete and join geometry might change normal output in an unintended wayto Geometry Node: Order of connection to Join Geometry node affect on shader local spaceGeometry Node: Order of connection to Join Geometry node affect on shader local spaceto Regression: Geometry Node: Order of connection to Join Geometry node affect on shader local spaceRegression: Geometry Node: Order of connection to Join Geometry node affect on shader local spaceto Geometry Node: Order of connection to Join Geometry node affect on shader local space@mod_moder
Just tested todays Blender Alpha build
bc86223975.Either your bugfix #106578 didn't work or it's not in today's build.
Still broken for me.
@Rincewind3D This is not yet an accepted option. And as a result, it will simply remove the dependency on the order.
sorry I'm not understanding your answer.
about which option you are talking? and what dependeny order?
Discalaimer: I'm a non Blender developer.
The local texture space of the object (mesh) is determined based on your transformations.
In geometry nodes, now when you joined multiple meshes, the texture space is only used from the first mesh. From this dependence on the order.
I suggested a fix. It hasn't been accepted yet. Its essence is that all texture spaces are used to average them.
But if you don't enter 1 mesh, the result will be different anyway.
Arg I was blind. Didn't regocnized that your PR wasn't merged yet. My bad.
Tested in Blender 4.0.2. This is still an open issue. Is there any reason why the fix #106711 from @mod_moder is not merged yet?
