Alphas look jaggy! Why ?

GlowingPotato · Nov 2015

Hey guys,

I'am trying to paint some height information using alphas. And even using 4k as texture size, my alphas look jaggy.
The image below shows my baked screws from my hi-poly, and an alpha.
Increasing the size of the brush, looks better, but I have artifacts. When using a small size, its look jaggy.

Any workaround?

Try reducing the opacity of your hiehgt layer or the Height Force slider in the Viewer options. If your height is too strong, it will magnify these artifacts.

You should make sure your height map is 16 bits if you want to get rid of the staircase patterns inside the larger brush.

I've converted the 8bits JPG to 16bits PNG, does't work... or converting is not the same as creating in 16 bits ?

No, you need a 16 bits source or you need to blur your alpha a little bit in Photoshop once converted to 16 bits to smooth the gradients.
