I do not notice the pianos and the strip objects are not collapsible.

Hello, how could you do that pianos and objects like the guardrails or fences are collisions ?.
And pianos? Step above and nothing, I do not feel them.
In properties I can not make clik in "colisinable" because it does not look like.
And go some .ini file? Or you have to click something on properties ?.

thank you for your help.

like road and grass, game engine wants to know its surface. title object name = KERB. example: 1KERB_01

for barriers, walls, fences, use "WALL" example: 1WALL_01,

for all collision wall objects it is good to make separateobject and invisible (set to not render in ac editor) & super low polygon count object in same place as the visual wall but you can still do it with main object by title name WALL etc etc
