I'm going to need to add a couple of parameters to CreatOverlay() in ModelOverlay.cpp. Currently the function receives only the base mesh def to work on, without skinning info. That base mesh has been extracted by the calling code using a function that has side-effects, so we don't want to call it a second time in CreateOverlay. Therefore better to pass the extra info as separate parameters rather than pass the parent render entity, which would entail CreateOverlay having to extract the info a second time. This approach also has the happy side effect of documenting CreateOverlay's new dependency on skins. |
