[Geometry Nodes] 'Realize Instances' node remove rotation information

Yerus

Hi folks! So, basically I had to use 'sample curve' and 'set position' nodes and for that it is necessary to 'realize instances' first, this removes the rotation I had done to the poles before...

Is there a way to preserve the rotations or transmit them to the post-realized instances? 

PS: I attached a modified file, removing the unessencial parts. On the first board you see the rotation I made to the poles, by 'realize instances' it removes the rotations.

Why not just do poles first   and instance them on the  curve after .It seams  curve to points node already have tangent and normal , no need to cross product anything either ?     

Just saying , perhaps you still need it that complex for some reason.

Hello! Yes, I want to create as procedural of a tool as possible, in a way you can decide to use or not the upper extension. Sometimes you have to accomplish a (root) process in order to go to another one.
Is there a way to get the rotational information from the first board? And shouldn't the 'Sample Curve' node be more acceptive?

You still can do what I suggested : input  generated post  to the instancer , not other way around .    Here I did it in your file

Brilliant! I think there will be no trouble doing this 'detour'. Thank you so very much! S2
