I started using Blender with cycles so it might be an obvious question but I couldn’t find anything by googleing.
The core of the problem is you can’t export textures to obj (+mtl) if you define the materials with cycles engine. But blender has Blender Render which works properly and can export the textures.
But… For background or high contrast textures I really like to use the the color output for displacement like this (works really good with wood, concrete and some types of cloth):
It’s a simple, fast, convenient way to add some realism without the need to create or find bump or normals.
In Blender Render you can’t do this. I know there is a displacement modifier, but couldn’t really recreate the results with simply using the image texture.
Is there any simple way to achieve what I want in Blender internal? If not whats the fastest way to create displacement?
Bonus question: Is there any way to export textures properly from cycles in to obj? (this would be the best)
