After I import FBX file(mesh model) to unreal, the quality is degrade. What is the problem?

This is mesh model which I made it in photogrammetry software

Then, I import fbx file which is generated in photogrammetry software. The quality is degrade. What is the problem?

How can I do to restore the quality that I see in the photogrammetry software ?

Thank you

What quality are you seeing that I am not? Also, lighting is going to play a big role. You need to setup the lighting inside unreal to match whatever software you are using if that is the result you are seeking. What software ARE you using exactly?

I made the mesh model by photogrammetry software called Pix4D.

The first and second picture are the view of the mesh model in Pix4D.

The third picture is the view that I just input the fbx file which is generated in Pix4D to unreal 4. I think the mesh model which is viewed in Pix4D is better. Do you know why the mesh model in unreal 4 cannot be similar with what I see in Pix4d?

Hey Felix,

since you have absolutely no clue yet on shaders, optimization, retopo-ing meshes, how ue4 works, and even the basics of ue4…

I suggest you start watching all the unreal engine related tutorials on unreal-engines own youtube page.
Because this… I cant even.

Hi felixho,

Here’s a useful link regarding what you are trying to do:

I am not familiar with Pix4D software, but like creating assets in any 3D Software, you will want to optimize the mesh so that has the lowest poly count possible while maintaining quality. Likewise, with the texture/materials they need to be in a format of a power of 2 (256x256 pixels, 4096 x 4096 pixels etc.) at the lowest size possible while maintaining the quality resolution at the distance they will be seen from.

That said, if your materials are correct when exporting from Pix4D, make sure your render settings are high in Settings at the top of the Editor window.
