I have found a way to cut the connector sections off the end of any piece of track that has a yellow connector piece. The reason this is unique is i can do it only using blockmixer, whereas others have done it before using custom blocks or block editing then embedding.
for example:
This allows you to get a new type of drop transition as wheels will not follow a dropaway piece if you wanted a straight drop. In the picture below you can see the old way you would get the front wheels touching the lower bit for a bit, altering the fall trajectory slightly.
For Comparison:
So far i have been able to reproduce this effect on any block with a height change so long as there is another block with the same height change and length. The method is as follows:
1). Place the piece of equal length and height down normally
2). Place the block you wish to have the ends cut off in block mix mode(f2).
3). Delete the 1st piece that was not block mixed.
Example of other pieces of track:
Let me know if this helps anyone or if anyone at least finds it interesting.
