Yesterday I tried to make an object but when I exported to Race Track Builder with Xpacker, it doesn't show up. Why this happen? I made it on Sketchup 2020, ksEditor does it load it with textures. So, what is the problem? It's maybe the Sketchup Version?
It all depends on the colors you give it, if you give it sketchup colors, they will still appear in black, if it appears in the kseditor and it does not appear in the game, it is very strange, because the last step is kseditor. we could help. and look at the faces in sketchp they are not the other way around
You can tell what object it is and if you can pass it to open it in sketchup and see if it is a failure from sketchup
Use 3d software, if you already spent 50 hours in RTB then you can probably watch this 1hr/30mins video - that roughly tells you about almost anything you should know about 3D stuff and in particular of course how to in Blender :
