Get same bump from a photo to a model I've been tinkering with this for a while but can't seem to find a good answer to my problem. I need to recreate the Activity Center from Fisher Price photo-realistically and I'm not sure how to go around the small bump details it has. I've been trying with a normal map I got from a photograph and it works sometimes and sometimes it doesn't. I don't know why it sometimes flips even if I didn't change anything. Also it's not giving me the quality I need.
I've tried getting a displacement map using CrazyBump but I'm not sure if I'm doing it correctly?

With normal map after it flips itself:

Correct normal map (but still not good enough):


Displacement map I get from CrazyBump:


It just messes everything up, doesn't even add the details or anything. I find weird how it would do that given that the map itself is all blurry but it seems good in it's preview ??


Am I missing something? Is there another way? Since it's for rendering I don't really care for how to achieve it if it works. I'm using Marmoset Toolbag for rendering but Blender for the model and stuff.
I'm not familiar with Marmoset Toolbag, so I can't speak for that part. But there should be a setting in there somewhere that you can adjust the strength of your bump map. It is the settings in your 3rd screenshot I believe.

In blender it works like this at least, notice the first image has a high strength on the clouds, the second has a lowered value for the clouds.



I don't believe this is a question related to Blender however since you use a 3rd party renderer, and it's the renderer that handles bump maps and such.

Hope this helps.
