—<\/p>\n

Features:<\/strong>
\n– Creates normal (bump) map from texture (works ok, with adjustable strength & optional blur filter)
\n– Basic Specular map calculation (on that main image specular map was handmade)
\n– If texture is not readable, set it automatically on for reading, then restore it to off
\n– User can cancel map generation (median filter can take a while on a big texture..)<\/p>\n

Todo:<\/strong>
\n– Editor GUI<\/del>
\n – Progress bar with cancel button<\/del>
\n – Optimize image processing (using setpixel now, setpixels would be faster)<\/del> (For now only in median filter)
\n– Try using invoke? then it runs in background in editor(?)<\/del> (not this time..)
\n– Documentation<\/del>
\n– Specular map generator is not good quality..<\/del>maybe in later versions can do better
\n– Set created normal map as [x] normal map.. (so that “fix now” button wouldnt appear)<\/del>
\n– Texture leak warning..<\/del> (it was from median filter temporary texture, it wasnt cleared with DestroyImmediate<\/a>)
\n– Request: Invert normal button (also invidual X, Y, Z flip)
\n– Request: Realtime preview (adding small texture previews first)
\n– Bugfix: AssetPostprocessor doesnt always run.. (Temporary fix, comment out line “if (!NormalMapMaker.running) return;”
\n– Feature: Add maximum texture size inside AssetPostProcessor<\/p>\n

Shader used on that image:<\/strong>
\n– BumpedSpecular\u00a0 With Separate Specular Map : http:\/\/answers.unity3d.com\/questions\/306921\/add-specular-map-to-shader.html<\/a>
\n– Added “#pragma exclude_renderers flash” to get rid off the shader warning..<\/p>\n
