Mipmaping, How to start?

wozzag · October 28, 2016, 7:23am

Hi All,

As the title says, where do I start?

Any good guides on the actual process of setting this up. I had a look and I understand what it is but I dont seem to be getting it to work.

My texture looks the same from distance as close.

Any help would be greatly appreciated.

Thanks.

This is a landscape tutorial but it also features the work flow of how to change texture with distance.

What I want to know is :

How to set it up.
Test it

What I have done below but nothing changes.
Are there any additional changes that I need to make somewhere ?

Here is a document on mipmapping Texture Properties | Unreal Engine Documentation

If U want to know how to change texture

1.In the post process volume the unbound option should be checked

2.Have AA Method setting checked and select “TemporalAA”

3.Select your texture

4.Under Mip Gen Settings select LeaveExistingMips.

5.Under LOD Group select the option “Cinematic”.

Yes I read that but it doesn’t seem to tell you how to do it, just what the settings are. I set it up the same as most examples but when I play my game it doesn’t change the texture.

I am missing something.

Hey wozzag,

Mip-map generation happens during importing of the Texture and creates a mip-map chain for the Texture. The mip-map chain consists of multiple levels of the sample image, each half the resolution of the level before. That data allows the graphic card to render faster when using the lower mips (less memory bandwidth) and also reduces the Texture aliasing (shimmering) that becomes visible when having detailed Texture in certain distances. The setting has no performance impact at runtime as it only affects the mip-map generation (during importing or when changing the setting).

Full Resolution Texture - Not Displaying Mips

Mip Level - 4

Let me know if you have further questions or need additional assistance.

Cheers,

Thanks for your help guys.

Andrew, I understand that but I can’t seem to get it working, I don’t see any visible difference in the texture on the static mesh.

Just to let you know, I am using one mesh.

I know that I can do it by swapping meshes based on LOD settings.

I am trying to get the texture change on one mesh based on distance.

Are there any distance settings I need to set ? or anything else ?

Apologies for the questions but really having a hard time getting this working

I try to debug the texture in the statistics panel but I dont see any change.
