hi,
I am a 3D artist .I need a height texture for making a diffuse texture.I think a height texture can help me get a good effect in texture painting.So I want to get a good way.

I known height texture can be get from Many ways .
1, From crazybump .
2,X normal
3,photoshop ( nvidia plug-in )
4,max baking .

Here ,I want to point out " Max Baking ". I render to height map .Found that some dark edge ,That is where the UVS is.

I'm a bit confused by your first bake there, I'm not seeing any of the details such as the pockets or buttons on the height map?

Anywho, people commonly use an ambient occlusion pass for these kind of things, that, and sometimes the green channel of a worldspace normal map.

Yes ,Fisrt bake map have some issue.Also I ues AO and green channel of normal map.at here .I love height map .I t give me a good feeling.If there is no black edge .I think it will good rather ran AO and green channel.

Height maps usually have artifacts you want to avoid, because they're sampling the difference in height between the lowpoly and the highpoly, so you get some lowpoly faceting in your map. Unless your lowpoly is completely flat, like a tiling texture.

Better to use an ambient occlusion map or curvature map. Some tips:
