Sometimes when the artist in working on a model and gets it done, he might face some issues when trying to get the models he did into Pyrogenesis. This page is dedicated to document and help you to identify the errors and their known solutions.
Each model must comply with a set of pre-determined requirements by the engine. If the model doesn't fulfil all of the requirements, the engine will pop up an error identifying where it failed. Example:
error: art/meshes/structural/classical_towncenter.dae: Assertion not satisfied (line 569): failed requirement "mesh has single set of polygons"
Known requirements errors and their solution
"mesh has single set of polygons"
This error may appear if the model has non-connected vertices or edges.
Fix: In Blender, to discard this possibility, enter face selection mode, select all with "A" and hide all the selected faces with "H".
Then change the selection mode to vertex, and hit "A" to see if there's any "lost" vertex or edges and delete them. After that, unhide everything (with "Alt+H") and re-export the model.
You may also try to use Select->Loose Geometry in vertex, edge or face mode.
"Found too many possible objects to convert"
This error is caused by several objects in the same .dae file. The engine can only read one object at the time per Collada file - excluding prop_points and armatures.
Fix: When exporting, you should use the "Export Selected" option in the Collada exporting menu - this option is present in both Blender and 3ds Max.
Make sure to only have 1 object selected - no cameras, lights, other objects, etc - an re-export the model.
