Convert maps from tmx to MP4 failing ?

[hackie]

I converted a lot of maps from TMX to MP4 over the years with great succes.

I always used this : ManiaPlanet.exe /computeallshadows /upgrademaps /useronly /fullcheck /LmQuality=High /titles=TMStadium

But yesterday after converting 600 maps something went wrong.
I made a screenshot of it :


Klick for bigger screen.

As you can see at the picture that only one map has a little map "icon" .
In total only 20 maps . from the 600 I converted , have such a little map icon.
Like I said , I converted already a lot of maps and never had such a problem.

The maps from TMX al have such a little map icon so that could not be the problem.
When I use the map editor in mp4 to brows true the tmx maps I see those icons.

After converting maps I can play them , thats not the problem , I just mis that mappicture ( icon ).

Any suggestions ? or is it een bug ?

Known bug. Try to see if in MP3 title the thumbnails works. I had that issue yesterday with TMN ESWC maps. Thumbnails did not work after conversion to mp4 (some of them did not work, rest worked perfectly) but in mp3 title they worked. Best example of MP3 based title is "compute shadows" titlepack - it's a tool to compute shadows without changing map author. There's editors tab, try looking your converted maps up there. If the thumbnails works, it's all good. If not, compute shadows via the title pack.
