I want to have a detailed model. The texture paint png file is like this (though these are the details on the mesh, I will create another paint file and want a bump map from that):
How do I make a bump map from this and have the black lines appear as ridges in the model? This is the model I want to create ridges on:
Will I need to subdivide the mesh? If so, how many times given the image? And will there be any problems because of the topology? Also, how can I see the effects in real time so that I can adjust the strength of bumps accordingly?
