Hello everyone,

Been gone for a long time, I hope you're all doing ok !!
I'm writting here because I have a question regarding city skylines. I'm currently working on some project involving a huge city with an aerial shot. I did the city in Blender using OSM, pretty easy and only 50K polys, which is amazing:

JHowever, when exported to obj or fbx and imported in iclone, there is a lot of flickering faces and I cannot find a proper solution to solve this. I don't understand why this is happening, the model is good and doesn't have any duplicate faces.

Is there a way to make easy and functional 3d cityscapes inside iclone without having this issue ?

Thank you in advance for your time and guidance,

This is obviously a Blender FACES problem after importing an OBJ in IC, I had to encounter the same problem and I figured it out, just connect the unsubdivided faces, all the black holes will be vanished!!

Select all in edit mode and hit Ctrl+T (to triangulate) or apply Triangulate modifier for all objects.

Thanks for your reply, I will try it =)

How do you connect all subdivided faces though? I had in mind Ctrl + J but I'm not sure...

In Edit Mode select the peering vertices to be connected, hit F on the keyboard to connect them :

I would not recommend an F to slice faces. It is overly time consuming and If you accidentally select 3 vertices, then a new face would be created over an n-gone face, causing more trouble.
If you must keep quads for some reason, then do it manually using a K tool instead.
Otherwise, triangulate all geometry to get rid of all n-gones in one shot, which would stop flickering.

The triangulate modifier seems to work like a charm! Thank you again you were very instructive and allowed a lot of time saving !
