Trapcode Form World Transform Problem

Hello,
In the Trapcode Form, I give a position animation on the Y axis from the Base form part. Then I change the axis of the form from the World Transform section and the form does not move on the axis I want. I didn't have this problem in older versions. The same problem exists with Trapcode Particular. Also, when I give the position animation from the Emitter in Trapcode Particular, it appears in the preview but does not work in the render.

I'm sorry for my bad english.

You are looking at a render order problem. Position happens first, then rotation. It works the same for a 3D layer. If you want the layer to move along the rotated axis, you have to animate the Anchor Point instead of the position. Otherwise, you just get a rotated layer moving straight back in Z space.

If you create a null in the Base Form section of Form, then you animate the Y anchor point of the Null to get the Base Form to move along the rotated plane. I'm not sure that Form ever behaved differently. To overcome the standard top-down rendering order for transformations you would have to have a switch in the plugin that specifies rotate before transform.

It did. This is a genuine bug or feature change.

Perhaps creating an actual camera would help. Seems weird indeed. The particles should move in the Z direction when rotating the entire world.

Thank you for understanding my problem. I added the camera but it still doesn't work properly.

I am experiencing no unusual behavior using AE 23.3 and the current version of Form.

I'm not sure that I see anything unexpected happening in your sample video.

Thanks for the reply. Previously called 'world transform', the transform should rotate the entire globe without breaking the position animation. I added another video. The correct working version in Stardust.
