Hi Nic,

I always use material- or object ID’s to replace textures. I’m not sure how to use UV-coordinates.

This is how it works with ID’s:
In AE you start with dragging the rpf-sequence to the new-comp button.
In the new comp you select the rpf-layer and use the keyframe assistant ‘RPF-camera import’. This creates a camera layer that has all the camera moves (don’t convert the rpf-layer into a 3d layer!)

Next you duplicate the rpf-layer and change its name into id-matte. Apply the effect ID Matte. In this effect you can select either a material or object ID you used in your 3d scene. It changes the alpha channel of the layer; in places where the ID is present, the layer is opaque.

Then it is time to set up the new texture. Drag the footage/texture you want to use into the comp; put it under the id-matte layer . For this layer you do switch on 3d.
Set the track-matte for this texture layer to Alpha matte.

So now your texture layer moves with the 3d camera and is only visible in the places it should be.
The last thing is to position it in the right place. You have to move and rotate the layer to the same spot the object was in, in the 3d scene. This can be hard, because your 3d scene might have used feet or meters or other units and in AE everything is in pixels. If you don’t have access to the original 3d scene, it helps to set up some solids as placeholders in the comp.

Hope this helps! Good luck.
Cheers,
Wieger

Hi Maxime,

This is probably an interpolation issue; change the first of the identical keys to a hold-keyframe and it will be solved.

Hi all, from PAL-country

Kevin is right about the pixel aspect ratio. If you need a comp for DV-PAL, you set it to 720 x 576, but non-square! (the right pixel aspect ratio is 1.09)
If you use square pixels, your text-animation will be stretched out in your NLE.

Hi David,

– twirl open your text layer;
– click on the triangle next to ‘animate’, which you can find to the right of ‘text’ in the time line;
– select ‘anchor point’ from the popup menu;
– now you can adjust the anchor point;

If you animate something like rotation after this (make sure you don’t add it to the same animator), it uses the new anchor point.

Hi Alan,

Do all your images have to fit inside the same circle? Because then a very easy solution in after effects would be to:
– add a layer on top of all the image layers (name it ‘circle-layer’);
– add a circular mask to this layer;
– duplicate this layer
– change the blend mode of the lower circle-layer to stencil-alpha
– add the stroke effect to the upper circle-layer and change the paint-style to ‘on transparent’.

Maybe another solution would be to create a 800×600 document in photoshop; import all your images as layers in this document. Save it as .psd and import this document as a composition in after effects.

Hope this helps!
