Hello everyone!

I have strange problem with default target of camera imported from pod file.
Well, I have scene with a cube, lamp and camera (this is a scene of default blender project). When I load this scene from POD I see black screen. Logging a target location shows correct location values. If I change default camera's target location I see rendered scene. And the most strange thing that it is enough to put the following code to get scene rendered:
[camera setTargetLocation:[camera targetLocation]];

So, maybe someone had the same issue? Please let me know if you know why I have such camera behaviour?

Did you animate your camera in Blender?

Make sure you have turned the Invert transparency flag on in your Collada2POD converter settings.

You can add the following to your initializeWorld method to display the names of the nodes and their bounds:
```
self.shouldDrawAllDescriptors = YES;
self.shouldDrawAllWireframeBoxes = YES;
```
You can add the following code to your CC3Layer to force the camera to pan to a position where it will view the entire scene:
```
-(void) onEnter {
	[super onEnter];
	[cc3World.activeCamera moveWithDuration: 5.0 toShowAllOf: cc3World];
}
```
As Rocketman697 mentions, don't animate your POD file until you've sorted this out.

I have no any animation in blender.
And I have checked on the "Invert transparency" flag in Collada2POD converter.
I still see black screen after I added the following code:
self.shouldDrawAllDescriptors = YES;
self.shouldDrawAllWireframeBoxes = YES;
Adding the "onEnter" works as following: scene starts with black and then I see my object moving to the center of the screen.
So it looks like camera target location is not initialized, because
[camera setTargetLocation:[camera targetLocation]];
solve the problem as I mentioned in the first post.

Ah...I missed the fact that the [camera setTargetLocation:[camera targetLocation]]; had fixed it for you in your first post.

We'll look into why that's the case. Thanks for reporting it.

Hope this help.

Thanks,
