Having troouble with work flow of game ready hair

nicko_the_great

Hey guys I've been stuck on this step on and off for weeks and no one has been willing to help. If anyone can assist me I am truly grateful. http://www.3dartistonline.com/news/2015/04/how-do-i-create-real-time-hair-for-games/ I made it to step 11 and that is where I am totally lost on what was the process before baking in Xnormal? I dont know what Im doing wrong, Do I unwrap the hair strands? Im completely lost

As far as I can tell, the idea is to create the hair strands so that they follow the UV layout of the hair cards you unwrapped before:

You are not supposed to unwrap the strands themselves. They will only provide geometry information which will be baked onto the textures of the hair cards. What might be confusing you is that the hair strands are supposed to be baked onto a flat plane and not the low poly hair cards (I don't think this is mentioned in the tutorial). It is necessary to keep the strokes mostly straight so that they can follow the layout of the UVs for the hair cards and don't have to be adjusted later on.

TL;DR: Bake high poly strands (following UV layout of hair cards) onto low-poly plane and use that as a texture for low-poly hair cards.

it's not necessary to do this step anyway. you could also simply take a render of the strands and use that for textures (zgrab for alpha), or use a hairsystem in whatever app and render from there - or simply paint the haircards or do them with curves, e.g. in a vectorgraphics app.

could you give a little more explanation on how you achieved this would be great. everyone I've asked has just been unhelpful and a dbag about it giving unnecessary comments. 

hopefully these posts helped you...
Otherwise this remark is pretty shitty for those that have helped you in this thread? 

So mrs.great i figured it out without asking people, are you even trying or wanted a step by step video? ^perhaps that would fall under dbag, just so the comment quoted is valid, now.

Actually yeah it did help a lot better than your explanation from my previous post. yay for you for figuring it out on your own would like a cookie? No need to be a dick about it but I guess that just who you are congrats dick. and yes people were being dbags about it. There's a reason why this is Tech forum is here for everyone to help each other, not to be a dick like you and say "go figure it out on your own I did" You have a pleasant day
