Trapcode Form World Transform Problem

New Here ,
Apr 08, 2023 Apr 08, 2023

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.

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.

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.

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.
