Author Topic: Normal/Hard surface stamp. Problem. Visibility.  (Read 1354 times)

Hello everyone. I have a problem. When i try use a normal stamp (predefined in substance painter) everything looks perfect. But when i create my own and try to use them its look lik someone set visibility in a half compared to existing stamp in SP. What am I doing wrong?

To bake normal stamp i use substance painter, then export normal map and edit in Photoshop, where i get rid of unused space on map and left only my hard surface shape. In the next step i import edited stamp into SP and use it on new layer after turning everything of except normal map.

Here is how it's look like:

On he top is my hard surface stamp.
On the bottom its predefined stamp from SP.

What is the resolution of your custom normal map texture ?

Everything in my project is baked in 2048/2048. And my stamp is baked in 4096x4096. I discovered something. Some time ago i created different stamp for SP and its look a bit different compare to the current stamp which i want use in my current project. When i put the old one into my project and use it on wall looks good (looks like sinking into wall).

And here is how the old one looks like compare to the new one.The one on the right looks more colorful and looks good in SP, why? Both stamps are was baked in SP. :(

Both normal maps looks fine to me, but they may not work as you would expect.
You have to understand that a normal texture describe the slope of the geometry. Imagine having a flat cube on top of plane and baking it down to a plane. In this case you will only get a blue and flat normal map, no slope, because both the plane and the cube have the same alignment.

So if you want stronger normal maps to stamp them down on your assets, you have to adjust your geometry before baking it down. Take a look for example at this image (source : http://wiki.polycount.com/wiki/Normal_Map_Modeling ) :
