When using GN for procedural modeling and utilizing the Point Instance node, the result can not be converted to a mesh.
Before:
After:
Any geometry generated by the Point Instance node simply disappears
Exact steps for others to reproduce the error
Result: Geometry generated with Point Instance node disappears upon mesh conversion
Expected: The entire visible procedurally modeled mesh, as is, becomes actual new mesh datablock

Afaict, this still holds true (and is the only way to get instances as real geometry.
Will double-check with geonodes team
Running the geometry through an
Attribute Fill
node will also makeConvert

Talked to @JacquesLucke and this needs documentation
Yes, but it will also cause this bug: https://developer.blender.org/T89470
So I have a choice between:
A, Not getting a tree crown I can export to a game engine
B, Getting a tree crown but without UVs so I can not export it to a game engine
:(
The main problem here is that make instances real operator workflow is abysmal:
This is just way too many tedious and error prone steps when someone just wants to turn the result of their GN procedural modeling workflow into an actual mesh.
@Rawalanche: I hear you.
Yes, I assume it would be best to fix blender/blender#85962 (Many Nodes (Join geometry, Boolean, Object Info?) and realizing instances remove UVs (output float2, not MLoopUV).) and make it clear why running this through an Attribute Fill is neccessary.
Using "Make Instances Real" is just the "workaround" in this scenario (and I also understand why this is suboptimal).

Since we have a realize instances node now, this report doesn't apply. The design has changed a fair amount, now we don't try to hide instancing and realize data implicitly. For the issue with UVs, we already have the other report that @licktwerk mentioned, so I'll close this task.
