[blender] Hair mesh too shiny

<< < (2/5) > >>

I created a diffuse, specular and normal map as well as added the alpha map as this tutorial has told me to do

I will edit my specular map and see if that makes a difference. Originally I made two layers for my specular map in gimp. first I would have a black background as my layer then the hair texture that was desaturated (with the levels altered a bit) would go on top of my background layer and I would merge the layers together. With the tips you've given me I'll change my black background layer.

Ah ok, looking at that, Dragon Age is pulling all the data it needs for the material from different colour channels in the texture ("R/G/B/A"), specular being the alpha-channel. Doing what it is, there's going to be an issue with your alpha - either its not there or there's some other problem with it, so check you do indeed have one - it should show up in whatever photoediting app you're using in the "Channels" panel.

I tested the process with CorelDraw and using the images from that link you posted managed to produce what looks like a correct image by splitting the channels into separate images using "Image >> Split Channels to >> RGB". I then dropped an actual normal map into the Red channel image, the Diffuse into the Green channel image and Alpha Mask into the Blue channel image. I then have to recombine the RGB channels back into a single image with "Image >> Combine Channels..." and then 'load' in the actual Alpha Channel image as a separate object over the top (from the "Mask" menu). Seems to work ok doing that.

I checked my .dds file and you were right my alpha channel wasn't there. My red, blue and green channels had the normal, diffuse, and alpha map respectively. I use Gimp instead of coreldraw so I added a layer mask and pasted my specular map in then applied the layer mask. I'm still getting shiny glossy hair. Besides desaturating my diffuse layer like you said is there anything else I can do to the specular map?

boodrl:
So I made a new texture and everything worked out the hair is a bit shiny but a vast improvement to what it was. Here is an image of what it looks now. It's not the same mesh but it had the same problems and I was working on this one. It looks great and I couldn't have done it without you kat. Thank you so much for your help!

kat:
Yeah, you'll need to play with the alpha channel mask but at least you know where the problem was happening now. Good Job.
