Hybrid Trunks Juxtaposed


z929669

Question

Hey sheson,

I'm hoping you can assist with an issue with constructing hybrids where I'm finding trunk billboards are not positioned correctly with the crowns.

Backstory: I'm working with Veydogolt Trees, and this mod is interesting in that it is purely a mesh/texture replacer and relies solely on vanilla (or whatever) plugins for tree definitions (i.e., this mod has no plugin). So the replacement trees are not necessarily like those references being replaced. For example, treepineforest01 might be referencing a completely different custom tree using the model name defined by the vanilla plugin, so object bounds are going to be different between the NIF and the vanilla reference in most/all cases. This is what I think the problem is, but I want to verify with you.

Link to assets - I'm providing all source, intermediate, and hybrid output assets for review. This particular tree is not a good candidate for flat trunk, but that's beside the point. I'm using this as an obvious example of the issue. I'm using DynDOLOD 3 Alpha 122.

The billboards are not correctly aligned with the crown, and I'm assuming to fix would require a proper plugin be created with Tree overrides and object bounds properly defined. The crown adopts all of the xyz and positioning of the base model, and so does the trunk, but since the flat trunk is taken from the rendered trunk, the hybrid lacks any specific xyz and positioning defined by the 3D trunk.

Can you sort me out?

https://dyndolod.info/Help/3D-Tree-LOD-Model explains how to create 3D tree LOD models from the full model NIF alone. Object bounds are not mentioned. Object bounds are irrelevant for 3D tree LOD models. Object bounds are only used to quickly determine if a tree/grass LOD billboard should be rendered as explained at https://dyndolod.info/Help/TexGen-Configuration#Tree-Grass-LOD-Billboards

The problem is LODGen that is used to combine the trunk and crown NIF adjusting the planes the opposite direction than they should.

Replace with this test version https://mega.nz/file/AMJ12BAT#RYNZgrk4IURbImGD7w1Te3VmqdCCFaCvPxCbABambGI
Run hybrid.bat and the created 3D LOD models should hopefully have properly centered trunk billboard front and side.

Link to assets and to mod are identical links. I believe you intended to link some custom ones in the second link?

The test version fixed it. Thank you.
