Do i need to sculpt manually every sharp edges on a hard surface model when baking

hegvbwkeuyrv

so i want to make a non perfect line when baking my game asset. Do i have to create those imperfection manually  then bake it into a game topo to get the non-straight line? or iis there a way to achieve this  when baking/texturing?

RawData

Do you use zbrush? If so , you can use polish which is in deformation palette and you can achieve more bakeble edges.

so yeah? sculpt it all? polish seems really uniform tho

theonewhoknocks

I think he meant the polish option in the deformation tools. It would be a slider. You can apply it to your whole mesh at once or mask out some parts and apply it to those only.

The quality of the answers you will get 100% depend on how precise you are in your description.

So far, "so i want to make a non perfect line when baking my game asset." means, quite literally, nothing.

@theonewhoknocks yes totally

@hegvbwkeuyrv if you polish your desired edges with the slider you can get more bakeble edges. If an edge is too sharp, it effects only a few pixels in normal map.

you could set up a warp modifier with a texture like perlin noise and set it to only affect edges (via vertexgroups)

@SnowInChina im interested, could you tell me more? Is it donw in substance painter?

SnowInChina

no, i meant you could add some generic distortion in your 3d app on the edges and bake it down

I guess you want to make some kind of edge wear? If so, you can make those imperfections in texturing program like substance painter. If you want to make big ones then you'll need to have additional geometry so you will need to make them manually. Or use some kind of modifier in max, or alphas in zbrush.

wait, i can add imperfection of the angle in painter??? its from baking proccess tho, can substance add an additional normal direction on the corner?

SebastianBielecki

It would be very helpfull if you'll add some screenshots about what you are trying to achieve Using normal map will only fake the imperfections, low poly geometry won't be changed. If you want to have smooth corner you'll have to bake it like that from hight poly. Maybe there are some techniques to achieve something like that in painter - i don't know. Imperfections to edges you can add using generators.
