I started playing around with terrain and I am getting this assertion in

QueuedRenderableCollection::addRenderable: "Error inserting new pass entry into PassGroupRenderableMap"

I am trying to find out what I have done wrong, but it is hard, so perhaps someone has any idea of what may it be.

I can reproduce it easily on my engine and my scene consists only of:

  • 1 terrain page
  • 1 mesh (highlander house)
  • 1 directional light

If I reload the scene and look again at the house the assertion fires and it is very strange. I have tried to debug the code and the only reason for the assertion to fire that I have found is the hash being changed after the node was inserted on the map.

Any ideas how can I find a solution to it? Which data and information I can provide to help debug this?

Also I have seen in the forum some posts about this assertion, but no one that I have seen explain ways to debug or to fix it.

Here is a bug report with a workaround, probably the same issue?

It was discussed here in the Ogre Forum.

  • \$\begingroup\$ @bcsanches No, I dont use Ogre, but I would start with the one in the bug report. Did you try it? \$\endgroup\$ Jul 11 '11 at 16:41
  • \$\begingroup\$ Yes, I am using it, just added it to the main lopp right before rendering a frame, so far it is working. \$\endgroup\$
