White lines between ground tokens

Hello everyone ! Here is my my setup : Chrome  Version 114.0.5735.199 No addon / extension Windows 10 22H2 It's been a while since I've been spending time creating maps and role-playing game sessions on the platform, but I don't post often on the forum as I'm a bit shy. However, right now I really need help as I'm facing a small issue with the grounds of my maps, let me explain. I have small white lines between each piece of ground on my maps. For example, on a small village map of 200 x 150 cells, to create the base of my ground, I repeat a mosaic square of grass (4 x 3), and there are small lines (about 1px, but visible and bothersome) separating each square of grass. I can solve this by taking each of the 12 grass squares and stretching them a little more (Alt + Stretch). However, it's a bit laborious, and I don't want to do this for all my maps (especially since I didn't have this problem about a year ago, I believe). My base files don't have any empty pixels or white pixels that would explain this. I'm using Chrome as a browser, but I have the same problem with Firefox, Opera, or Edge. I had the problem with my old computer and with my new one. The files are quite lightweight, around 400 kB. It's not visible everywhere at all zoom levels, but it is noticeable in most cases. The images are snapped to the grid, and I reduce the opacity of the grid to 0%. So it's not simply the grid (which I use to arrange and move elements more easily). What makes it particularly annoying is that the tokens above (houses, trees, rocks, dirt paths, shores, water, bushes, etc.) appear on top of these lines. As someone who strives to create the most polished and immersive maps possible, it ruins everything, and if I want to fix it, it's incredibly time-consuming. I have a 500 x 500 cell map where it ruins everything, and I've spent 600 hours on this map. I need to finish it before presenting it to my players, and I feel like crying. The map is enormous, and I'm going to have mismatches all over the place with my 81 ground tokens. Currently, my only solution is to give up using the grid, which is detrimental to my maps even though it's supposed to be helpful. If you know a solution to my problem, if it's possible to fix it, if you have any ideas, other than going through my approximately 121 maps in detail and spending 300 or 500 hours just resizing ground squares and fixing mismatches because the grid isn't working well, I'm listening and would be grateful for any help. For example, a small cavern entrance : Or a small village : And on an airship, through the clouds : They are always visible, and every time a player comments on it, it breaks my heart, as if they were saying, "The quality of your maps is decreasing even though you're spending more and more time on them." I would like to regain the fun of making maps without this inconvenience. Myskown

Where are those lines in the airship one? It kinda looks as if those maps are pieced together where the line is displayed. Did you create the maps yourself or did you just upload them and bought / found them elsewhere?

If you could post or post a link to one of the tile images, it might be helpful to analyze. Sometimes resizing an image can create pixels that are semitransparent along some edges.

If you are 100% sure the tiles are not involved, can you test with the following Page settings ? (in the Background section) - board color set to transparent - backdrop color set to transparent - set 'Apply Dominant Color From Map Layer' to off Maybe the board color is set to white/bright gray by default and the 'Apply Dominant Color From Map Layer' setting cause only the backdrop color to change and not both the board and the backdrop.

Hello everyone ! Reik H., thank you so much! Your solution worked! I applied the settings you recommended to each map where I had these small lines between each floor texture, and I got my maps back to how they were before, without those white lines (borders)! TheMarkus1204, I created the map myself, I import all the elements separately (floor, house, rocks, trees, bushes, smoke, ship, fog, water texture, relief texture, rocky wall, etc.) and then build my map directly on Roll20. It's a bit laborious, especially managing the map layer, but it allows me to modify the map during my sessions based on actions and events. For example, the floor texture (grass) comes from: <a href="https://www.forgotten-adventures.net/live-gallery/" rel="nofollow">https://www.forgotten-adventures.net/live-gallery/</a> (Home / FA_Mapmaking_Assets / Textures / Natural_Textures / Grass) "Grass A 05" on the first map and "Grass A 07" on the second (from my previous post). After inspecting it, I don't see anything that could explain these empty pixels between each token. The entrance of the cave with and without the mentioned lines (before and after) : How does it work ?&nbsp;Why is the board color applied as a border on my floor textures ? Thank you so much for your invaluable help. I would have never figured it out on my own, and I would have never thought that the board color was involved in this issue. Myskown

Go to your Game Settings outside your campaign: You want to disable "Apply Dominant Color From Map Layer" and also set "Backdrop Color" to transparent. (Backdrop Color is the color displayed for the area outside the Map) IN GAME now, hit the GEAR Tab and check the Miscellaneous Category for "Apply Default Settings". There you want to ENABLE "Backdrop Color" AND "Apply Dominant Color From Map Layer" and hit OK. WAIT for it to finish and everything should be fine again! Myskown said: Hello everyone !
