I have 4 textures. Bump, displacement, specular and diffuse. Please what node combination would help me get the best render for this mixture. A screenshot after the node setup would be nice.
If i understood the question here the answer
With the powerful addon Node Wrangler in built in Blender you can set the node automatically.
Make a folder and paste all the images (Bump, displacement, diffuse, specular).
With the Principle BSDF Node selected Press Ctrl+Shit+T
A pop-up which need to access all the images made above folder. Select all (Press A)
Press Principle BSDF Setup and your done . Render it with F12
Just use new principled shader (Tutorial):
And if you want to use displacement, you can connect it directly to material output node.
