How would I go with painting my own normal map from scratch? Experimenting with a better workflow than the traditional baking here.
>>1019553>better workflow than the traditional bakingWhy are you reinventing the wheel? To answer your question use substance designer
>>1019553Bake a sphere that you can then use as a color picker. Going lower poly will help you reliably pick colors. Some programs offer such pickers out of the box
>>1019557Nice idea, I think instead of lowpoly you can also try to quantize the colors.
>>1019554fuck off from the thread dickmunching faggot
If you work on normal maps in sRGB it's going the get messed up.
>>1019553Look at a normal map of a object with easily recognizable up/down left/right in the green and the red channel. You can hand paint great looking normals by hand by painting a pair of grayscale images with a gradient in the correct direction of shading. Download filters for Photosop like xNormal or the Nvidia normalmap filter and you can normalize the result of that to generate a matching blue channel.>>1019554Hand painted normals has a lot of utility and is a powerful technique once you get the hang of it.Perhaps you are trying to add deep normals to a existing photo texture of something, or you're otherwise adding normals to something that inherently has no geometry, like a 2D painting etc.There are many valid reasons why you may would wanna generate a normal map without having to bake anything. Pic related is another way of doing it, paint in your curvature as a mask and then sample colors from a normal sphere and replace the correct looking colors at the corresponding angles.
>>1019569For reference this is what that model looks with and without hand-painted normals.
>>1019570To create the mask you just make a selection where you wanna drop down shading and create the gradient with a proper size soft brush the side similar to how you paint shading with an airbrush.

>>1019564Quantize will be somewhat random about it, low poly mean you can deliberately choose what sort of angles are important to you
>>1019553You could try drawing it in black+white then converting it into a normal map with laighter. I haven't done that, admittedly (or maybe I did and forgot), but it's worked well for when I wanted to convert image textures into normal maps so I don't see how it'd fail to do the same with a black and white image.
>>1019596> You could try drawing it in black+white then converting it into a normal map with laighterThat's a bump map, it can't express a full spectrum of what a normal map can. It doesn't have reflection "angles" basically, it only has height. You can convert any bump map to a normal map, but you can't convert any normal map to bump map without losing information.>>1019589Trvke.
>>1019604>That's a bump mapI know? That's why I suggested converting it into a normal map with Laighter.
>>1019658Not really "converting" because that's impossible, at best it can "generate" a normal map from bump map, and in terms of angles I think it's gonna be the same as baking normal map from geometry? Which kinda defeats the purpose, because custom angles is what people want handpainted normal map for, and here you skip this step altogether and let automation pick the angles according to some hidden prebuilt algorithm.

>>1019668Handpainted normal maps have been a thing in the industry since Halo 2
>>1019668> lowpoly retro tranniesNormal maps were never used in old lowpoly games, and they are extremely rarely used in new lowpoly games, and when they are, those are the crazy hybrid styles you won't ever confuse with anything old.
>>1019668True>>1019671What industry? Ain't nobody paying for hand painted normals, might as well light your money on fire.
>>1019684the game industry, chud. stop shitting up threads.
>>1019553You can make a height map and use gimp's filters to convert it to a normal map, ive done that once or twice
>>1019715HAHAHAHAHAHAHSHSHHAHAHAHS
I've seen like two blender addons that let you paint normals on the mesh itself
