Have you tried to rotate the object.. move it... test it in different positions... see how it behaves?Try it again with some other object and different texture... something more simple.Or if not... start looking in to the software you are using to create the object and texture, maybe the problem is there.As I told you before, my problem was from Photo-Shop when I had my "black texture" problem.

Tried Diff assets, Diff Poly counts, Diff Angles, Diff Textures,  All render great in UDK and Cryengine,  They are only having
those odd shadow effects in Outerra.

Please send me COLLADA file for the "big object". The cube issue was caused by engine bug but this is different.

If you can't see the attachment, it is on the upper right of the screen.I don't know if its a visual bug on my side of the line.. but in case if it is the same... that's where I see it :D.

I started playing with the object, rotating it, touching it with the ground... and the "shadow" is persisting only on that side of the object.

Details about the geometry... it has a 20,0 unit range on the edge around the face, 400 height and 265 width.. you can see from this print screen:



The height of a "soldier" model that you have from the engine is like 75 and 85 units height, maybe it gives you some perspective of the values.

And if it helps... I think this shadow bug is chained with the older "black with stripes" texture bug.I still have 2 screen shots I think with it:

It's a depth buffer nonlinearity problem when using large coarsely tesselated objects in connection with huge view distances. There's a fix that slows down things a bit, but we want to make it adaptive when objects get close.

We'll make the fix an option in the configuration in the next version.

Just checking on when you think there may be an update posted.  Would love to see our many assets placed in
Outerra.  If you need any further assets to test with just shout, we are happy to help get the problem resolved.

Thnx

Oh almost forgot about this, going to add that workaround flag.
There's one perf.problem with time flow on Nvidia that we need to fix, after that there will be an update.

From what program are you exporting the models? When we load it into Blender and then export from it, it looks ok. It seems to be a bug in the importer, but we don't know what is causing it yet.

The problem is certainly in the importer and it is probably cause by Y_UP parameter.
