I currently see two ways: 1) Enable interactions for the current decals (idRenderModelDecal, which is actually not derived from idRenderModel). The problem here is that interactions will be cached as part of interactions with the owner entity, which is usually static. So one has to hack frontend to force regeneration of interactions with owner whenever that is a decal on it. 2) For every decal, create a separate idRenderEntityLocal which represents it. This involves some lifetime management (store links, delete decal REs when owner RE dies). But then frontend should work out of the box, and interactions too (basically everything should). The model should probably be DM_CONTINUOUS, so that it can regenerate alpha every frame. This might also be more costly performance-wise... |

Here are some generic changes: r11021 Renamed idRenderModelDecal -> idDecalOnRenderModel, idRenderModelOverlay -> idOverlayOnRenderModel. r11022 Optimized Bvh build slightly. r11023 For two-sided material with interactions, make sure to set ID for duplicated surfaces. The last fix is quite critical: I won't be surprised if previously two-sided material randomly stopped working. And here is the implementation of the feature: r11024 Implemented projected decals which can generate interactions. r11025 Force using decal models with interactions by default. As of now, the new decal system is force on by default. If we discover some issue with it, we'll use both system depending on material flag. If not, then I guess material flag "forceInteractions" should be deleted. |

The crashes on start were noticed in Written in Stone. Both on Linux and on Windows + Sanitizer. Here are two fixes which make the mission stable with Sanitizer: r11027 Fixed bug of iterating over area references while being modified. r11029 Handle mirrored vertexes properly in reusing cached decal model. And a bit of refactoring: r11026 Tiny refactor of local variables. r11028 Instead of flag geometryHasChanged, deleted cachedDynamicModel to make sure it's not reused. |
