ME: Image Rendering Error

[Ciaphas]

The top image is the original image (512x512, .jpeg). The bottom image is the same image rendered in game. There seems to be a lot of loss happening. Any particular reason why?

 

Original image:





Rendered in game:

Not a loss so much as it appears to be processed as a surface effect that is not normal (square on) to the viewer and with shading effects - you can see this in that the upper edge of the picture is not "level," as you would expect were it facing directly toward the viewer.  Note also that the button surfaces appear offset from the center of the button?  It appears that those buttons are rendered as 3 dimensional objects, but indented rather than standing proud of the surrounding surface.  The light effects on the sides of the buttons seem to mirror this.

I've run into this before. 


One time I exported the Briefing room and stated pulling it apart in AC3D.  It looked like the briefing screen has a poly object that is positioned in front of image surface that is supposed to simulate a spotlight shining down of the wall.  I suspected that additive effect was washing out the images bit depth. I was going to experiment removing that but I never got around to trying.

Mission briefing are something that have never been used much, so few have ever seen those problems.

Moving the camera position as close to dead center as I can doesn't appear to change the look of the image.

This leads me to believe that the way it's being applied to the screen object might have something to do with. Think of effect layers in photoshop.

If there is a poly effect (a plane, 'er face) simulating light, I think it should be removed and the environment lighting should be relied on instead. Unless that plane is an emitter in which case it could be removed and one area light should be placed in front of the screen between the screen and the first row of chairs using a moderate strength setting.

but... if the environment lights already in place will suffice than there is no need to add another light source or any emitter object.

just my 2 cents

Yeah, I had mentioned a similar suggestion to Hitech a while back.  I'll add it to my list with some addition tweaks. 

[Ciaphas]

Getting this image to render in Blender 2.8 is super simple. Getting both images above is done through over saturation of the lights in the scene (Sky, Point and Area) though the point and area lights are not on at the same time.

[Ciaphas]

Here is the same image, applied to a plane, 1 point light (Strenght: 1000 Watts), three angles.


*** No render settings have been assigned to this plane, it's just using display rendering (not EEVE or Cycles) ***

What laws are you talkin about. Also what formats are you saving the image in

Not sure about the laws?


The image is .jpeg

In any event, I removed the images of them keys for the moment. They weren't needed in the end.

I will be using them later down the road.

Damn spell-checkers.     I think he meant "loss".

Look at Ciaphas' original post:
   Note the difference in the background color.
   Note the drop shadow below the keys.
   Note the shading of the key bevels.

Luckily his text was high enough contrast that it survived.   However I have put up BW images where a significant portion of the image ended up bleached out to the point of almost being white.

I originally thought there was some kind of spotlight objected shining a  harsh light on it in the briefing room.  But taking the object apart in AC3D I think I remember there was an overlay poly on top of the poly the image gets rendered on  that was maybe trying to add the effect like a gloss.  I didn't get around to trying to remove that and re-importing to see if that fixed it.

I would prefer to use .png or .tga for image files because of their alpha support. I could also just recreate the image as an 8bit .bmp and see what that does. Should be simple enough. let me test this.

Was supposed to be flaws , typo from laws, I.E. I'm not seeing exactly what you think is incorrect.

Post your raw image.
