What is the displacement map workflow in UE4?

Hi guys. I am still pretty new to unreal or game shading in general. I always used mr or vray so I am confortable with prerendring.

I want to get resutls similar to 32 displacement maps u get in vray. Is it possible to achieve something similar in unreal? I want to add realistic shaps to characters than just boxy normal maps.

cheers for reading :slight_smile:

A good place to start Check the ‘World Displacement & Tessellation Multiplier’ heading

Thank you

But it doesnt say what displacement maps it supports and honestly it doesnt explain what those nodes are. :frowning: Could you please explain? Thank you

It supports DDS textures. Usually a greyscale image representing the height of a given area. Which you can multiply with the vertex normal to offset the vertex by the given height. You use it with tessellation to get more detail.

Hi ,

We haven’t heard from you in a while so we are marking this answer as correct for tracking purposes. If you still have questions regarding this please feel free to comment here or on our forums.

Thanks, TJ

I actually have a Question since I did not find any other place to get the information.

I have the Displacement map imported in UE4 so how do I exactly ad it in so that the material gets the “bump”? What nodes exactly I need since I tried to connect Displacement map to world position offset but it seems to not work :stuck_out_tongue:

hi,

thanks for reply. I still haven’t come across a solution for this. Its really embarrassing to admit but I feel my knowledge on the whole process in game displacement is very limited…I barely know the process for it. Please also understand I barely used UDK in the past so its better to not assume I know it a lot!

I am not so sure what a DDS texture is as i have only worked with tga/exr/tiff
