I made a small gradient texture in GIMP to use as an alpha mask for hair ribbons, but in blender, the bottom (top) edge of the texture has a dark line on it where it should be white. What does it mean?

Two unrelated things: pretty hair, and slimy tongue material.

I'm back again! I had a another shot at baking textures.

Geometry: made via HairTool addon. (It's literally just the default settings for everything, applied to a cylinder. )
Texture: made in maya 2016 via geo maya hair 2 script (It has to be maya 2016 or 2015 for texture baking to work, apparently)
HDRI from HDRIhaven (they're CC0! Come get some!)
And rendered via RenderMan.

By default, HairTool seems to create all the ribbons on the same spot on the uv map. This makes textures not so interesting. So I made 10 strands, then in the UV editor selected all islands and scaled them by 1/10 and packed islands. This made them all evenly spread in a perfect square shape for the GMH2 baker to recognize.

I attached the textures, since they should work for anything with a planar geometry/square UVs. (But promise you won't use it for commercial use, as it was made in a student version of Maya. )

By the way, HairTool lets you convert particle hair to mesh hair ribbons. So if anyone has particle hair they want converted, you can send it to me and we'll see how it turns out. (HairTool addon is paid, around $30USD or so)

Ignoring the features that have been removed and HOPEFULLY just haven't been put back yet, blender 2.8 really is quite lovely. It's like taking photographs.

(Although rendering has been sped up a lot, you still might want to reconsider getting 2.8 yet if your computer isn't as as beefy as mine, as although the viewport rendering is lighting-fast, there doesn't seem to be a way to turn if off... Which makes it still only a fun toy rather than something I'd use all the time, as the apparent and inexplicable lack of even a wireframe mode makes me irrationally angry. )

edit: OH.... I feel like an idiot again.... for anyone brave enough to try 2.8, it seems you turn off the silly auto-render by switching to blender internal or game engine.

Blender 2.79b + denoising + Principled shader "random walk" subsurface + hdrihaven + basemesh + Hairtool

You can make braids with hairtool now

I spent today compiling the human head with SSS shader in different settings/colors, but for now, have a head covered in weird metallic goo.

Your hair tool experiments keep intriguing me, but I haven't quite pulled the trigger on paying up. :D

In your image the back lighting seems to reveal some transparency artifacts with the "stringy hair". Is this an intrinsic fault of the tool, or just an unhappy circumstance of this particular scene and the lighting choices you made while playing?
