In 3dsmax, toss a "turn to poly" modifier on top of your stack, set the number of sides to 3, export and then you can remove the modifier and go back to working with quads.
Yes there is! sort_circle_tool for Maya: vimeo.com/65246315 (download in comments, it works best with border loops) And Loop regularizer for 3dsMax: http://www.scriptspot.com/3ds-max/scripts/loop-regularizer
Yup, there are normal maps applied on all the textures. Are you talking about in the UDK render or just the 3dsmax render. I'll try cranking it up a bit in the texture or the slot.
Thanks for your quick reply :-) I was not aware of that one. Thanks! Is there a way to make it stay inside the utilities tab of 3dsmax or you always have to re-run the script?
For the box cap that showed some irregular quads, you can improve the quality using the comments made in the 3dsmax thread http://polycount.com/discussion/comment/2515374/#Comment_2515374
oh and if you want ready rigs, here few links: https://instantrig.com/ https://shalabology.wordpress.com/free-stuffs/free-rigs/3dsmax/shiko-new-rig/ and Mixamo.com
Looks tight, are you using 3dsmax? if so you should add some fancy shaders too the highpoly and preview some texturestyles and what not. Very solid work!
