Dynamic Lightning of Columns or Trees

I wanted to add lightning blockers to trees and columns, in a simple square form, to make the scene more spooky, but 5 grid-squares behind the obstacle between two lines of darkness appears a lit area. Is this my mistake or is this an actual error.

Can you provide a screen shot of your dynamic lines?

A few questions:

1. Do you have a light source back there? You as the GM will still see light sources even if your players are not in sight of them.
2. If your players are seeing the light source even though it is blocked, do you have "enforce LOS" turned on in the page's settings?

Hope that helps,

Scott

Here is the Sreenshot the Fire is the only lightsource in this example and its the sight of the red-haired female character. "Enforce LOS" is on.

From that, it looks like the fire has sight enabled too so the shadows you are getting as a DM are from the view of the fire and the red haired token.

Try selecting the player token and using CTRL+L (CMD+L on mac) to 'see' through their eyes alone, that should show solid shadows in the hidden areas. Alternatively, uncheck 'has sight' on the fire (which i'm still assuming to be the issue...).

The red-haired token is the only token in the scene with sight. The fire has checked All Players see light and an 50m Emits light radius. The pic was made with CMD+L from the red-haired tokens view.

Leon, "Rejoin as Player" is a different way to examine your dynamic lighting scenes. Try this next to make sure you are not seeing some oddities due to how the Control-L method shows it.

First go onto the Red-haired Token > Edit > add yourself (GM / Leon) as one of the players under Can Be Edited & Controlled By. (Note: Don't let yourself have Controlled permission for other characters or tokens with sight, just for the one that you plan to test, the red-haired in this case.) Move the Player Ribbon onto this Page of your game.  Then go to the gear-settings icon at the top right, and choose Rejoin As Player. Now you will be seeing what the red-hair token's player would actually see.

The appearance in this mode can be a little different, a little more accurate to what Players actually see, than what the GM gets by using Control-L.

I did that. Sadly i see exactly the same as with Control+L

Ok. Can you describe a little more about what the problem with the appearance is / how you want it to look different?

From my understanding so far and looking at your screenshot -- is it the trees that have 2 shadows (forming a "V" shape of shadows) that you don't want?

Perhaps, try as Franky suggested, go on your Dynamic Lighting Layer and take a screenshot of that so we can see your DL lines and give feedback.

Correct i want the light area between the v to be dark as well.
Hear´s the Screenshot you asked for:



I had the idea to add more edges so i made some trees with the polygon-line tool (red).
As you can see hear that did nothing:

It looks as if, because of the small blocks you're using, they're allowing too much light to pass through the trees, creating the wonky effects you're seeing. To fix this, you would need to expand your DL lines to block light to the areas that you want.

I think that you're seeing the "v" because you've only got one light source and it's separate from the token with the line of sight. There are areas behind the trees where the light does not reach creating one shadow and then blocked areas of sight from the token's perspective creating a second shadow. Try turning on global lighting to see if it goes away.

Kirsty said:

That sounds like the right interpretation to me. Leon, is this, possibly, what is intended after all for the reason Kirsty described? Global Illumination might get rid of that effect indeed, but it might be that the current effect is Dynamic Lighting's way of representing what Leon has set up: a fire that gives off light (casting black shadows) and a red-haired-person-with-sight whose sight is blocked by trees (casting blackness).

You still shouldn't get that interior v of seen area though behind the object. Leon, how did you make the DL lines for blocking the trees? I'm wondering if you at some point used the circle shape or the freeform draw tool (through one of the hacky ways to access it from DL layer) to draw these and so it's having a hard time correctly processing everything.

As Ziechael noted, the shadows seem to be from both the fire's as well as the girl's POV, which is just weird because in GM view it should just show light levels, not what every token sees (and in CMD/Ctrl-L it should only show it from a single token's POV). Even if the girl's token had a light emission (which I don't believe it does from what you've described), you wouldn't get the pattern that we see in the images as DL lighting is additive and so if she did have light emitting from her, you should wind up with just a thinner/no sight blockage depending on the tree placement in relation to the two light sources. Of course, this doesn't explain why one of the shadows for any given tree traces directly back to the red hair girl token and one to the fire.

For the sake of 'the complete picture' could you supply screen shots of the token settings for the character and fire, as well as the pages settings?

Ok, thanks all of you.

Yes Global Illumination gets rid of the effect but only because it turns on the sun and the shadows cast by the fire can´t be seen anymore. It´s supposed to be nighttime on the map i just cranked up the fires radius to 50 so the effect would be easier to spot. 

If i´m getting what Gold and Kirsty are saying correctly it make sense how it is displayed:
Take the V´s in the lover left corner the right line is there because the sight of the token is blocked by the tree. The left line is there because the light of the fire is blocked by the same tree in a different angle, so technically the token can see there but since theres no light it doesn't. Anyhow it can see beyond that were there is light again.

So it´s not wrongly displayed it just looks weird.

Thanks again
