[tonycho]

Hi guys if anyone know how to make bump or specular map from simple JPEG
we know that our clients never give us that map except simple JPEG

so if anyone know the info for plug ins or something, it will be great help for everyone

for sample I attach the map of some fabric, maybe someone want to render it and show the tips

Thank you very much guys

Do you use photoshop?

Filter > Other > Hi Pass, and set the pixel radius to 2-5, depending on resolution and desired detail.
Now use the levels to boost the contrast a little bit.
done.
That´s how I create my bump maps.

you can also desaturate it and then use nvidia's free normal map generator plugin for photoshop http://developer.nvidia.com/nvidia-text ... -photoshop, normal's map usually look better than bump maps
