Scale is negated in inverse bind matrices.
Vertex weights are normalized (glTF importer is limited to 4 weights per vert).
Fixed interpolation for animations where the first frame is not at 0.0.
Allows cached.dts version of assimp imported shapes to be loaded.
Vertex weights are now correctly assigned for skinned meshes. Portions of the vertex weight fix were taken from: https://github.com/ConfettiFX/The-Forge/blob/master/Common_3/ThirdParty/OpenSource/assimp/4.1.0/code/glTF2Importer.cpp#L823-L860.
Inverse bind matrices have been adjusted to be consistent with the other importers.
All nodes, joints and meshes are now named so T3D can cross reference when loading animations.
All T3D specific changes have been bracketed in //T3D_CHANGE_BEGIN and //T3D_CHANGE_END tags to make them easier to find when the assimp library is updated.
This commit deals with the problem that the keyframe timestamps are not standardized. Seconds, milliseconds and ticks are used depending on the import format. There is no metadata or property that specifies the format used, so the option is exposed to the user as part of the import options gui.
Fixes material initialization for texture and transparency assignments.
Lists all available material properties to console in debug builds.
Adds TORQUE_PBR_MATERIALS define for testing with PBR branches.
Caches textures to disk for shape formats that support embedded textures.
Only the compressed texture codepath has been tested. There are a large number of binary gltf files with embedded (and pbr) textures for testing here: https://github.com/KhronosGroup/glTF-Sample-Models
The lodType, singleDetailSize, adjustCenter and adjustFloor options been added to the importer.
Implementation of $Assimp::FlipNormals has been fixed.
$Assimp::FlipWindingOrder has been added to expose aiProcess_FlipWindingOrder.
Logging is now enabled and directed to assimp.log.
Original PR broke class-type visibility toggles in the editor, so this adjustment on the same setup keeps the optimized path, but also enables the original class-based render toggle if the editor is open.
(Also adds TORQUE_TOOLS check to have it be even leaner if the project doesn't have tool support at all)
