I would like some help with maya particle instance orientation.

[9617ljs]

I would like to inquire about the instancer method using the Maya particle goal.

I want to make a scene that follows the terrain above,

I want to make it move so that it is perpendicular to the uv at the point where it is located like the red ship (?) in the image.

Currently, it only controls the progress direction like blue, but it is not positioned like red.

I tried connecting the goal point normals to the aim direction and userVector1PP =<<0,1,0>> to the aim axis, but it did not work.

Ummm.. I think I need to connect (?) the aim axis to the y-axis pp attribute of the ground's local vector, if anyone knows how, please help

Can you share the .ma or .mb file? Easier to debug and help.

Thank you so much for your interest.
I have attached the working file. I'm still trying various things, but I haven't been able to solve it.
Your touch is a light to me.

I'm thinking of a way to access this by getting and setting the local coordinate values of the vertex normals. Can I get some help on how to do this?

To be honest I do not remember, this old stuff with the nparticles and the instancer, since I have not used it in ages. I believe this is easier to do in BF than in the old system. You can control basically everything that you want inside BF and create your own field, push points towards the surface, etc.

Thank you!
Practical applications are expected to move animals moving in cycles.
Could you please send me a link to the BF tutorial video for reference?
If realization is possible in BF, I want to study hard.
