i downloaded the backyard example forum the 3dgs download page. If i load the .wmb file everything is working fine. But if i open the level in WED, add a simple rubbish bin and build it as "Build Simple Map", the Level looks like this:
Just the textures directly in front of the camera are shown correctly.
Okay... i don't want to convert them. But if i place a simple rubbish bin in the level and press "Update Entities" an run it, i get an error: "BACKYARD34.WMB: Bad file format".....
thats because the level is made with a6, so the .wmb format is also old. And if you Update Entities, then you replace some wrong lines in the outdated .wmb .
