I downloaded a small V4 map, changed version="3" to version="4" and activated my old theme.
I just see a blank screen.
What is to do? Doesn´t the features of the Locus V3 rendering engine work any longer?
Is there any description for Locus themes of all tags I can use?
Another candidate is the Waymark v2a theme. It is together with Elevate
invaluable for long distance bike trekking along international a/o national cycle route network.
As most themes render cycleroutes too late and often do not distinguish well the route classes ( ICN,NCN,RCN,LCN).
E.g Native Locus hiking/bicycle touring theme shows routes at zoom 13+ what is too late for big picture with ICN or NCN only. Additionally, all have the same colour.
Elevate cycling renders ICN/NCN at Z8-9, other routes at Z12. Similar for Waymark theme.
Waymark theme has additionally a great feature to turn on/off route classes independently.

Locus uses the standard mapsforge engine for maps V4 and higher. As the Locus extensions were never ported back to mapsforge, they can't be used.
I made a reference which tags are supported by which mapsforge version here:
https://www.openandromaps.org/en/oam-forums/topic/mapsforge-rendertheme-reference
@Tobias,
Thank you, your reference is very helpful.
And now I understand, that for V4 maps Locus only provides a general theme and no specialized themes at the moment
Unfortunately a few (for me) needed attributes like "scale-icon-size", "scale-font-size" and "style" (missing in your reference) are not available with Mapsforge V4 maps.
So I hope, the LoMaps based on Mapsforge V3, will be available in the future.
LoMaps will be converted to MapsForge V4 renderer system, hopefully in the near future (during next year).
Anyway because MF project seems not to be dead like in times I started to write own modded version, I'll instead contribute changes back to the official version.

Good news :-)
BTW, are you planning to update the V4-maps engine to mapsforge 0.12.0? This finally adds curved path text rendering, which is great for street names:

We may give it a try ... but next version, please. Rather not to change it a day/two before release.

Another candidate is the Waymark v2a theme.
In another post I provided an example of using a script to semi-automatically convert outdoor and Waymark v2a locus map v3 map themes into v4 map themes for locus map. Here is a link to the post:

I hope ManfredG doesn't mind me using his Waymark-v2a theme as a guinea-pig. It might not work perfectly in v4 maps and certainly hasn't been checked rigorously. But it would probably make a good starting for point for creating a v4 map version of the Waymark-v2a theme... But note, it is a very large theme consisting of over 8700 lines!
