Hairstrands obj scatter -> 90 degrees rotation


Trying to scatter bunch of dynamic objects (trees) using the hair system. Problematically 90 degree rotation is required for it to align to hairstrand. This artificial alignment will corrupt dynamics. Please advise me of what is the best solution.

Thank you

On the trees, tab into edit mode and rotate them 90 degrees until they are aligned properly on the emitter object. Make sure you realign the origin so it’s at the base of the tree.

Thank you Photox however the problem is that by rotating 90 degrees the physics simulation will not work correctly. The best solution that i have come across is to use PC2 cache (caching sim, then rotating) however I am still interested to learn if there is a better way.
