Shadermap 4 vs bitmap2material

Hi guys,

I am interested in turning some photo’s into normal maps etc for use in blender and found 2 programs I am interested in hearing opinions on. Crazybump seems to be the most used one but I find it to expensive because I might use the software commercially at some point. Do any of you have experience with shadermap version 4 or bitmap2material? Which one would you choose to work with and why?

I like that both programs have a nice UI but I can’t find much info on shadermap isn’t it popular?

Thanks!
