4.5 to 4.6 Preview - Graphic distorted

Update my game from 4.5.1 to 4.6 preview and game graphic got distorted. I am using ‘Emissive Color’ property for all the materials(Characters).
BG assets are Paper2D sprite which also use ‘Emissive Color’ in its base material.

UE 4.6 has added new feature : ‘Precomputed Direct Lighting from Emissive Materials’, is this issue, a side-effect of this new feature or do I need to handle some setting?

Note:- Game FPS raised from 28-32 to 148-151

Attaching image for more clarification:

Hey -

This looks like your texture Filter settings may have been changed between the two versions, or mipmap settings have been changed. Can you take a look at that and let me know, the “Precomputed Direct Lighting from Emissive Materials” should not be causing the blurriness like I am seeing your images.

Thank You

Hi ,
I just double clicked open the texture to check the texture properties:
In both engine versions
Mip Gen Settings - NoMipmaps
LOD Group - UI

Only change I can see is:
Compression Setting - TC Editor Icon (in UE 4.5)
Compression Setting - TC_UserInterface2D (in UE 4.6)

Hey -

Let us try this, go into your textures and uncheck sRGB and change the filter setting to Nearest (by default it should be a From TextureGroup). Finally change the Compression to TC_Default? Since we are seeing the FPS climb so significantly it has to be a compression setting that is getting turned on between the two versions. Do you happen to have any Console Variables set in the *.ini files in 4.5, if so try to copy those over as well into the new 4.6 ini files?

Let me know -

I tried your suggestion but no use.

Unchecked sRGB and graphic got worst than previous (image attached).
Filter setting was already set to Nearest. I tried switching to default but still no use.

Finally toggled Compression to TC_Default again same, no effect on graphic quality nor on FPS.

No I don’t have any Console Variables set in the*.ini fles.

I updated another project and even a sample PlatformerGame to 4.6.

PlatformerGame from 4.4 to 4.6 - graphic are getting blur.

My other project from 4.5 to 4.6 - facing same issue graphic are getting blur and in both case FPS is increasing.

Note : I have updated engine through launcher and not from GitHUB.

Hey -

I am not able to reproduce what you are experiencing. Is there any way you can package a project (yours or an example) in both versions that show this appearance difference that I am seeing in your pictures so we can continue to test this issue.

If you need to keep the project private feel free to private message me via the forums.

Thank You and in the meantime I am continuing to test this issue.

Hi ,
Please check your inbox for the link.

Hey -

I received your projects and am beginning to run some tests. Initially it looked like I was able to reproduce it and see you problem, but on closing and reopening both projects I was unable to see any difference again, so I am attempting to parse exact might have changed.

Thank You

On selecting Play on Mobile Preview, i am not facing any issues, but in editor and all other options its still same.

Hey -

Sometimes we forget the forest from the trees, can you look in the editor and see what the Engine Scalability Settings are set to? Change them all to EPIC and see if you see a different result in Editor something closer to Mobile Preview.

Thank You

Yup that worked … I am laughing hard :smiley:
