as you can see on the attached files the texture gets desaturated if the receive decals attribute is turn on…
and if it of the decals aren’t working anymore (obviously…)
the textures guys in our team are going crazy because they just dont get the result of the textures they are see in Photoshop.
we are working on a flat, saturated look and with this problem it is super hard to get the textures working correctly
is there a workaround??
i dont want to give up the decals but its also ■■■■■■ to add all textures in two variants…
FYI i added this:
r.EarlyZPassMovable=1
r.EarlyZPass=2
r.DBuffer=1
into the
BaseEngine.ini
under
[SystemSettings]
hey eric,
no i dont wont to switch the decal blend mode nor dosnt have to to with decal.
it because of the object (static mesh, bsp ) and/or the material.
if you deactivate on an object the receives decal attribute cou can see that the object gets slightly darker and more saturated.
this it the correct look of the material / texture i want to achieve.
but i want this look with the ability to use decals…
Obviously I did in fact read your question incorrectly, but now that I see what you are asking I am beginning to look into this issue for you. May I ask, what is the roughness setting on the Brickwall in your example photos?
its the wall out off the content example project, the decals map…
i tested it with different roughnes spec and metal values no change, but here
at home i dont have this issue but i have not the decal tweak in the setting…(r.EarlyZPassMovable=1 r.EarlyZPass=2 r.DBuffer=1 into the BaseEngine.ini under [SystemSettings])
i will test it again with the tweak tomorrow…
OK it Seems to be fixed in the 4.4.1 version at home
with and without the BaseEngine.ini Tweak.
i will keep you up to date, after we switche our work ue to 4.4.1…
Make sure when you test you remove Eye Adaptation for the best test results, as any change in coloring like that will trigger the Auto Exposure feature in the Post Process.
mmh interesting approach…
but this is not the reason. at the work project is Auto Exposure disabled…
as soon as we update our editor i will present you the outcome…
Could you post a screenshot of your Decal Material Setup or a test version that is behaving the same way? I want to look into this further but I want to be jumping off the same point as you are.
ok finally we updated our engine and the issue is gone!!!
but its decals still need a direct light to work property, if the light is not bright enough the decal is fading away…
and the tweak ( r.EarlyZPassMovable=1 r.EarlyZPass=2 r.DBuffer=1) i not also not helping!!
You will have to change the Decal Blend Mode to one of the DBuffer settings (a good default one is Translucent, Color, Normal Roughness) which will give you access to the DBuffer which you have turned on with the above BaseEngine.ini variables.
Here is the example of the same setup with a DBuffer Decal:
The way that the DBuffer works with the Lighting in the level currently restricts the use of the Emissive channel, but DBuffer is a work in progress so I can let our engineers know that we have a user requesting it.
For the time being though you would have to use the none DBuffer Emissive Decal.
