2 Bump Maps are possible for one plane?

[FLOGGER23]

I have the curiosity, what if i want to create a bumpmap for raised panels/rivets and one for engraved ones, how possible it is???

Far as I know, you can't overlay two bumpmaps on the same piece of mesh.

 

But having a bumpmap that shows ups and downs is easy.

Black usually shows depth,while white gives you ,highlights..(.raised look..) on bumpmaps

make your basic bumpmap base ..I usually use a jpeg.....I set all panel lines to pure black 100% opacity sunken rivets\panel lines  for raised rivets..... set to 100% opacity...black....then inverse the colour to white...purer the colour the deeper the bumpmap
