Importing 3D objects into AE - some points missing?
on Sep 27, 2012 at 1:28:49 pm

Hi,

When I import some 3D objects into AE 5.5, some parts of the object are not visible at certain angles. It doesn't happen with every 3D object. I'm looking to get a wireframe look - see the screenshot attached.

My process:

Build an object in 3D software, or import one from elsewhere.
Save as .3ds
Import .3ds into Photoshop
Save as .psd
Import .psd into AE as Live3D object
Rotate the layer controller in 3D.

I've tried adjusting the 3D Render Settings in Photoshop to remove/not remove backfaces & hidden lines, but can't seem to find a setting that works.



Screenshot shows Photoshop version on the left, and AE version on the right, with missing vertices.

Thanks in anticipation :)

Tom

Instead of using Photoshop to do this, does your 3D application allow you to animate and render out wireframe views of the object?

Yes it does, and I could do that, but I was wanting to try using the objects directly in AE, as I haven't managed to use the Live3D mode successfully before. I've also go Trapcode, so could go the Mesh route using Form, but was hoping to find out why this isn't working...

Cheers,
Tom

The more I look at it, it seems to be because the "dish" in the image above is very thin - possibly only one "vertex" thick.. I think this is what's causing the problem, so I'm going to attempt to extrude the dish a bit, and see if it fixes it...

Just to let you all know, this is what the problem was - infinitely thin shapes don't appear in AE.

If you extrude them slightly, this solves the problem.

I believe this is known as "rubber ducking" :)
