Imported object scale and brush quality

hey,

I modeled an arm robot in blender and unwrap it then exported as .FBX with applied scale to substance painter and baked it with no problems now I want to paint some screw heights by alpha brush I have but when I reduce my brush size to paint on object the quality is really bad and not the same as normal brush size. So how I can get good quality from small size brush on my object and what causes this problem is it about my object scale or alpha that I use (alpha is 2k res) ?

It is, but the Texel density is related to the UV islands and UV map size. Some of your UV islands are really small and details on those parts won't have enough texels for a clean result.


Therefore, I'd advise you to use a the UV Tile workflow. This way, you'll have several UV maps for the same model, so a better definition.

Hello @digihamid3d,

 

Thanks for the question.

 

The issue is neither the object scale nor the alpha. The problem comes from the UVs and the Texture set's size.

 

First of all, the UV islands must take as much space as they can in their UV map. The UV map will have a defined number of pixels (1024x1024, 2048x2048, etc.), therefore, if the UV islands are only taking a small portion of the map, it isn't using as much pixels as it could, resulting with a poorer definition.

 

The Texture set's size will change how many pixels defines the UV map; more the pixels, the more the definition.

Tell me if you need anymore guidance.

my uv is packed very good and texture resolution is at 4096px but still I dont know how that small size brush could be done. I searched so much and I think its all about density and texel thing.

Thanks your solution also helped me. I need to make several texture sets to make more space for more Texel Density.
