I want to import an FBX model to my sandbox file but the save button in the mesh import box wont trigger a save as window.
I have looked at a bunch of different tutorials on how to do this but i am missing this step.
This is the best one I have found https://www.youtube.com/watch?v=o4vpWF58qIE
I tried this one too but its a different version than what I have. https://www.youtube.com/watch?v=JEZTcz24xeE

I loaded my file, tools> FBX Import> Mesh> clicked all the right checkboxes I need, no materials, just need the model in-engine right now. I click save to get the save as cgf file dialog box but nothing happens no matter how much i click the button. Here's a screen recording of it: https://youtu.be/xYwCyglc9ZA

figured it out. User error my fault I hit a wrong button. The process for this is still way too fucking long to do but whatever I got it:

tools>fbx import>mesh>
import mesh window
click middle folder button
find the fbx through file>import
select file hit import, cryengine box popup hit import
then hit cancel in the next box
back in main sandbox view
see imported fbx in create object tab> static mesh entity
drag into project.

Just posting to tell you there should be a quicker way. Press F2 to bring up the Asset Browser, and then you can just drag & drop the FBX File that way. Need to change anything for the Mesh just double click on it and it will bring up the FBX import tool.
