Feature Requests ：Generate Normal(＆Bump) Map

[Precision7510]

I want a filter or function that generates normal maps and bump maps from color images, as in Photoshop.

Filter >> 3D >>
Generate Normal Map ...
Generate Bump (Height) Map ...

This video will be helpful.

 

 

By the way,
I want a mode called Combine Normal Map that can combine multiple layers of normal map in the layer composition mode.

Krita is the only paint software that synthesizes some normal maps,
but I think many 3DCG users in the world want it.

FilterForge is a terrific plugin that specifically supports Affinity Photo. FF includes a number of different normal map filters and bump map ones.

It also is a great general texture generator with PBR support and up to 65000x65000 seamless texture export with normal map, metallic map, roughness map, occlusion map and height map automatically generated as well.

But yes, would be nice to have built-in support like Krita.

Photoshop plugins for heigh/normal are absolutely useless.    As well as  a whole way to make height from a regular photo too.      Nobody use that filter and its existence as well as their  approach for 3d painting   demonstrates   nobody in their company understands what people working in CG  need.   Normal maps done that way looks absolutely awful  under tangent light angles:  blurry , inflated  , terribly mismatching.

Their Alchemist soft can do more or less  acceptable  guess what height should be looking like  from a single  photo  by using its  AI  but is still nowhere close to   true height you can capture with photogrammetry series , lidar device or by sculpting it in Zbrush and such.

 

What we really need IMO  is a live filter that turns  b&w height image  into  correct normal map.   Lighting filter some people suggested to use for that   makes inaccurate  normal map vectors  but I bet it would takes Serif just a day to make perfect normal map live filter since my bet it could be using same math  and basically needs a few tweaks

Here is a 'height to normal map'  live conversion I did  from lighting filter and few gamma tweaks   but it works more or less correctly only in 32bit document when exported as tga from it.  Serif , make it just live filter  please working in any bitdepth  and look into Krita source code to recreate normal map blending mode
