Hi,
I'm trying to draw polyline but nothing is shown in the map
here is sample of code
val polyline = mController!!.addMarker()
polyline.setPolyline(Polyline(list, HashMap()))
polyline.setStylingFromString("{ style: 'lines', color: '#009ecc', width: 28px, order: 1200 }")
polyline.isVisible = true
any idea wha's the problem ?

hello guys, I'm struggling with tangram-es, I'm getting this "WARNING urlClient.cpp:375: Failed with error for url: The requested URL returned error: 403" while I think I've correctly set my NEXTZEN_API_KEY and i use the default scene.yaml ... any help ? thanks Guys

my cmd is "./tangram -f ../../scenes/scene.yaml", it is able to find the yaml file but ...
the build was ok
it generated the tangram in build/linux
Is there a way to position the camera/projection for a Tangram map in a similar way to navigation apps? E.g. https://raw.githubusercontent.com/mapbox/mapbox-navigation-ios/main/docs/img/navigation.png

I'm still working through this library, but I'm sort of feeling stuck. I need to be able to animate a circle growing a certain velocity from a point. It seems there isn't a circle polygon, but maybe drawing a circle could work, but then how would I animate it? The other option seems to be a shader, but I'm not certain how I would place a shader on the map and have it render at a specific point? I've been searching for hours. Please, if anyone has any suggestions or examples, that would be great!
Like there is a shader circle example: https://github.com/tangrams/blocks/blob/gh-pages/shapes/circle.yaml
But then how do I place that on my map with Tangram ES?
Then I assume I would have to figure out how to use shader code to animate the circle

I think you would need to pass a new uniform corresponding to your animation parameter
Hello all, I have a problem. I want to overzoom a vectorial map that have data available only until zoom 8 on a mobile Device that run a UBUNTU base Tangram ES SW on it. All ok until zoom 10 but if I want to overzoom more, the icons and texts have rendering issues..like here:

Do you know which can be the cause? Is possible my mobile Device OS have some limitations or bad configs? Or my scene.yaml is not ok?
On PC viewer and Tangram Web all ok with my scene and map
So that they can be used with tangram-es default styles (e.g. the scene.yaml in the repo of tangram-es)
@mathisloge take a look at https://github.com/systemed/tilemaker ; you could customize the tile creation via Lua to match the tangram/mapzen cartography
Did any one obsered that loading a Vectorial layer for example on low zoom (for example zoon 3-5) and set max_zoom: 5 (max zoom to request tiles) and max_display_zoom:18 to overzoom last available tiles set untill zoom 18...there is a huge memmory leak (I can easly reach RAM limit even on a PC with 4 GB RAM only by zooming IN and zooming out more times). Each time the RAM increase until limit is reached. It seems a n issue in Tangram rendering overzoom textures
I used latest version available on GIT to obtain this issue(is also obtainable on older versions). Is there a special settings I must consider or this is a known issue?
Exist possibility to upload a grid map? I have 5x5 degrees coverage for every map and I want to upload several in the same scene.yaml. The maps has same layers and same data type. Only covered surface is different. I can view concomitant several maps of the same type?
Helllo people!
Can tangram-es render raster images with a specific bounds? (not tiles, but a single areal image)
I have seen options for this in tangram-js but i cant find any hint regarding such a feature in the tangram-es code base. i just want to be sure i did not miss anything :)
Cheers!

I have a question regarding collide on icons. It seems that only by opening tangram on a certain zoom level, sometimes it collide some icons, other times other icons (without moving on map or do anything else). Is collision done randomly? Is there any solution to have always same icons collide? Because if we zoom in and zoom out on same location, icon first presented dissappears and other icon is displayed.
Hi @xuzhanya have you tried following the steps on the Android README page? https://github.com/tangrams/tangram-es/blob/main/platforms/android/README.md
Somebody know if Tangram ES accept layer update without relaoding the scene.yaml each time?
I plan to have a Pi with GPS attached. I'd like to serve a local webpage with a Map and GPS pin. Does Tangram help with this? Or is there another project I should look at?
