    An odd one. I found a xpack with a grandstand which fit the style of my WIP but it had no canopy cover. The grandstand does have the framework for a canopy however. So I tried to lay a wall flat and make it into a canopy. It is visible in BTB. When I export to GTR2 the grandstand is there but the wall canopy is gone. I go to run a race and the wall canopy is visible from the grid. I do a lap and it is gone... I do another lap and it is there... Very odd. Anyone have any idea why this may be happening or how to fix??

    Every polygon has a front and a back, and by default 3d games to only show the front. The quickest method is to go to Venue Materials [​IMG] and make the wall's material double sided. If that material is used on ordinary walls you will have a higher polycount because the back of the wall will be drawn as well as the front. In that case it might be better to add another point to your wall, making it a squashed < shape and setting the X or Y scale to stop the texture stretching.
