Fusion camera to MAX and ANAMORPHIC :)


Post by xmare » Fri Nov 08, 2019 7:47 am

Good morning /evening to You all, issue-lovers!

got a curious case and i am looking for a bit of guidance.
Got me some nice footage shot on alexa sxt. i was a nice vfx supe, so i know that it was in 4:3mode (2880x2160) and the camera had primo 75mm anamorphic lens.
SO - i use my favorite "Swiss knife a.k.a. Fusion" to setup the cameras for the shots. My steps:
- setting project to 2880x2160 / pixel x:2 y:1;
- importing footage
- setting the camera angles and with geometry [not perfectly aligned but more than decent]
- 3Drenderers with said settings - 2880x2160 / pixel 2:1

Everything is good sofar.

so i exported the scene to fbx , along with BG plate, and tried to check / get the same result/ To no avail.
camera was imported incorrectly (not 75mm). so i had to do a little bit of gymnastics and the closest i got was:
Max Render setup:
2880x2160, pixel 2:1
i did change the default aperture from 36mm to 23,76 [alexa sxt aperture in 4:3 mode)
however i needed to divide the camera lens by 2, resulting 36,5..
still it was not perfectly on point with fusion 3D render; i had to scale this up by approximately 4% and move a bit up...


So the question is - Does Anyone can have and can share the missing part/ingredient to get the perfect alignment from Fusion to Max?

thx for Your Patience ;)

I don't know if help you a lot, but...In the opposite way (max > fusion)

With .fbx (few years ago), always used FBX version 2009 and unit factor to Meters (if max is centimeters).
And of course (in 3dsmax) check out the backPlate ...
