Trapcode Form – Orient Textured Sprite to Center
Hello, I’ve created a sphere and I’m using sprites as a particle. I can’t seem to figure out a way to control the 3D orientation of the particles. They all move as one.
Is there any way to have each sprite auto-orient to the center of the sphere as it rotates? I thought about connecting a null to the X,Y,Z rotation settings in Trapcode but again, they all move as one.
Thanks for any help.

Rather than using the built-in Sphere base form in Form, you might be better off importing an .OBJ file. If you use the Textured Polygon setting for the particles, they should align to the normals of each vertex, essentially laying flat across the surface of the sphere.

Hey Matthew,
This is such a good tip, but I’m having trouble with it.
I’m getting the textured polygons to orient to an OBJ sphere.
The orientation looks perfect until I try to rotate it within form.
Once I try to rotate it within form, the orientation breaks, see?
Could it be that my OBJ has not been exported properly? I’ve just used VideoCopilot’s low-poly sphere because it was handy.
8274_spherelow.obj.zipI’d like to be able to rotate my form sphere while I fly a camera through it, but this is making me crazy.
Cheers,

I see the same problem if I use the rotation settings in the ‘Base From’ section, but if you use the ‘World Transform’ rotation, or orbit the camera around the Form object, it looks OK to me.
Hope that works out for you…

RIGHT! The world transform!
I’ve now parented the World transform rotation and position to a null for ease of use.I’m ultimately filling those guys with video and they’re coming in at all angles, so I think I’ll move to MamoWorld’s Distribute 3D sphere expression:
