Mojo lighting issue when spanning monitors.

[Richard BetsonParticipant]

Hi,

I have included an image of an issue I get when spanning multiple monitors in a Monkey window.  It seems when I  have two monitors and resize the window to encompass both lighting on the second monitor falls apart. It appears if lights have an issue on the second monitor. Non-lighted images seem to draw OK.

This image is of a monkey window spanning two monitors. The side with the background image is my main monitor and the side without a background is my second monitor. Both monitors are using my GTX 950 on Linux Mint 17.2. I am currently using Monkey 2 v.1.1.01.

Hi,

As of version 1.104 this is still an issue. Lighting looks to lock-in at a default of the screen (monitor) it launches on. For example if you have multiple 1080p monitors mojo2 seems to lock lighting in at 1920×1080. Resize (or a static width) the window to say a larger width and any lighting beyond 1920 (width) will break.

With mojo3d in the works support for lighting in windows spanning multiple screens or monitors should be a concern. Would like to see this fixed for mojo2.

Picking up my third 27″ monitor today so hot to see mojo2 supporting above.

Rock on.

Hi,

Just did a lighting test with 1.1.0.5c.

The good news is lighting appears to work spanning across multiple monitors. The bad news is the lights are artifact-ed or blocky looking. It will do this in a single window (where the window matches the monitors resolution) or spanning monitors. There is also a shimmering effect when moving images. I’ve posted an image as an example. If needed I can record a video of the shimmering effect.

System: Linux Mint 17.2 Nvidia GTX 950.

Is it OK to report issues about the development branch on Github?

Edit: Hopefully you can see what I mean in the images.

Edit 2: The red and blue lights are scaled up to better show the stepping/blocky light issue.

Does this happen with ‘simplelight’ or other bananas?

Can you describe the issue better, I can’t really see anything from the screenshots.

Can you try on a PC or other hardware?

[Richard BetsonParticipant]

Sure..

It looks like an issue with scaling the light image. I have included two images of simplelight running on v1.1.0.5c and v1.1.0.4 which shows the different results when scaling a light image. I changed the following line in simplelight:

Monkey

_light.Scale=New Vec2f( .5,.5 ) 'to _light.Scale=New Vec2f( 3.5,3.5 )

1 2 3 4 5

_light.Scale=New Vec2f( .5,.5 )   'to   _light.Scale=New Vec2f( 3.5,3.5 )

 

Maybe it’s an issue with mipmapping? Is it off by default in v1.1.0.5c?

Ok, potential fix pushed to the develop branch at github – you just need the latest version of modules/mojo/graphics/image.monkey2

[Richard BetsonParticipant]

I think that got it. Looks like it is working as before (v1.1.0.4). Thanks for making this all a priority. You-da-man. Going to be plugging in mojo3d into my Alien Phoenix project here soon which should be fun. So far testing mojo3d on my multiple monitor setup seems to work OK.
