@Lo2k:
A request for the next GP4Builder version. I assume it's a feature which is quite easy to implement as it already exists partially.
When creating track from .dat we have three checkboxes for track, pitlane and kerbs and we can chose which of these three we want to create.
Could you also add a checkbox beside each track part and its texture (tarmac, lines, verges, banks, rails, kerbs)?
I have added the checkboxes on this image to show what I mean:
This way you also could delete the kerb checkbox at the top in the 'choose objects to create' field. Sometimes I just want to add only two kerbs in the pitlane and the 15-20 other track kerbs are also created so that I have to delete them again. With the new system I can select the pitlane only and then the kerbs.
Maybe it does not seem so but this feature is extremely handy...at least for me. I noticed it when modifying Monaco. For example if you only want to create new trackXX and lineXX objects you have to delete 6x<number of track sections> objects after converting .dat file (2(left and right side)x3(banks, rails, verges))...if a track has 900 sectors, that would be 540 objects you have to delete manually if you only want to keep track and border lines.
