Hi all,
I've already set up a 3d scene in 3dsmax for a still plate with a moving head that I want to geotrack. Also, I have aligned the head geometry very precisely in the 3d file so that I can project texture onto it at a frame I have selected. I have exported my camera as an alembic and my 3d head but, of course, the 3d head comes in at the origin. Is there any way to preserve its transforms so that when I import it into PFtrack along-side my camera alembic file, they will match as in 3dsmax? So my head doesn't have to be aligned a second time in PFTrack?
Any help much appreciated.
Kind Regards,
Nathan.
Yes. The alembic worked perfectly thankyou so much.
Hi Simon,
Thanks so much for your quick response. I haven’t tried exporting my mesh as part of the alembic. I just used obj as it wasn’t animated. It just needs to match on the frame I remodeled the head over and projected textures from. Then I will track forward and backward from there. I will give it a try tomorrow. Sounds promising!
Thankyou again.
Kind regards,
Nathan.
Hello Nathan, I've checked this out here in PFTrack 24.12.19 using an Alembic file I generated in Blender and it appears to be working correctly. I created a mesh object and camera, and exported them as a single Alembic file, then in PFTrack I used the Edit Camera node to load the camera from the file, and the Geometry Track node to load the mesh as a moving object. When loading the mesh, it isn't positioned at the origin and is placed in the same location that I specified in Blender. Have you checked your Alembic file in another application to make sure it contains the correct transforms? If it all looks fine then perhaps your file is storing the transforms in some way that PFTrack is not understanding. If you can upload your file here then I can take a look and see how it's storing the data.
