How can I achieve box projection with blend for procedural 2D textures using only nodes and without using UV map?

Question

How can I achieve exactly that mapping, without UV and with only nodes?

This is the closest that I achived.

And it is not bad, but blending doesn't work. And it is very hard to come to a solution how to implement it in a performance efficient way.

Whole node set up.

No, I want the same effect only with procedural(2D, without Z axis) textures. @moonboots — Mikhail Gavrilec, Mar 26 '21 at 08:30
Maybe check out @Rich Sedman on triplanar mapping (This answer and its refs) — Robin Betts, Mar 26 '21 at 14:56
@RobinBetts Thank you, but projection on a sphere looks awful, with that solution. — Mikhail Gavrilec, Mar 26 '21 at 16:36

"Blend" is a 0-1 range value, with 0 corresponding to nearly no blend and 1 corresponding to a pretty loose blend.

Not appropriate for anything feeding displacement, as normal depends on displacement; if you need box mapped displacement, bake a UV mapped texture.

Can't really make out your nodes to see how similar that is to what you have.

Yeah. It is a very good solution. Thank you for your hard work to help me, I will try to go over nodes to understand decisions you made to solve this problem. – Mikhail Gavrilec Mar 26 '21 at 18:50
