Software for height map creation?(Zbrush alpha grab doc alternative)

RawData

I have a tileable sculpt and i want to grab a height map from it. I tried blender to render depth and export as png but it created lots of stepping. Is there any other way to have this image. I will use it as a tileable texture in Painter.

To avoid the stepping, render in a higher precision format, like 16 bits. You can try Tiff, Hdr, Exr.

@csprance suggested same at discord server and it worked. Also thank you very much

Why not bake it in painter ?

@poopipe painter has no option to bake a height map AFAIK and also i have a blender scene set up for tileable sculpting, i can just open it up and sculpt whatever i want than render with one key and i have my map. It is more comfortable for me i think.
