Yes friend, you can do it,
It`s very easy, you can do it in various ways, but i will explain to you the way i do, for me, it works perfectly, with all the animations intacted, and even i can re-export it to FPSC.
However you will need some tools.
Lets go:
1) You will need Fragmotion Software:
http://www.fragmosoft.com/
2) Then you will need the Source Model File Importer for 3dsmax (download and install this plugin):
http://www.wunderboy.org/apps/smdimport.php
3) Now open Fragmotion, and open the file (conker.x)
4) Then in fragmotion after you loaded the model, you click on the texture tab to find the conker texture (it will not find automatically).
5) Now in fragmotion you click on file > export > half life 2 smd
6) You need to do 2 times the export procedure. On the first time you will export the mesh model (you will see an option to select what you want to export), and on the second time you will export the animation. Save the model file with a name like "conker_model.smd", and save the animation file with a name like "conker_animation.smd".
7) Now open 3dsmax, and select file > import > source model file (smd). Import the file "conker_model.smd", relink the texture file (maybe you will need the 3dsmax dds plugin to view the texture). Save the file as "conker.max".
8) Now in this same file, you will import the "conker_animations.smd" and 3dsmax will automatically add the animations to the file, without any errors!!!!
Hope you understood.
Cheers,
