From 1463fc889b65524794f2f7d9cf661aa673d58e06 Mon Sep 17 00:00:00 2001 From: "K. S. Ernest (iFire) Lee" Date: Mon, 20 Sep 2021 18:24:31 -0700 Subject: GLTF for game templates. Convert GLTF Document to use ImporterMeshInstance3D. Add a GLTFDocument extension list and an extension for converting the importer mesh instance 3d to mesh instance 3d. Use GLTF module when the editor tools are disabled. Modified the render server to be less restrictive on matching blend arrays and have more logging. Misc bugs with multimesh. Always index the meshes. --- modules/gltf/gltf_document.cpp | 321 +++++++++++++++++++++++++---------------- 1 file changed, 199 insertions(+), 122 deletions(-) (limited to 'modules/gltf/gltf_document.cpp') diff --git a/modules/gltf/gltf_document.cpp b/modules/gltf/gltf_document.cpp index 3f1f218e78..c7818e7e86 100644 --- a/modules/gltf/gltf_document.cpp +++ b/modules/gltf/gltf_document.cpp @@ -33,6 +33,8 @@ #include "gltf_accessor.h" #include "gltf_animation.h" #include "gltf_camera.h" +#include "gltf_document_extension.h" +#include "gltf_document_extension_convert_importer_mesh.h" #include "gltf_light.h" #include "gltf_mesh.h" #include "gltf_node.h" @@ -49,6 +51,7 @@ #include "core/io/json.h" #include "core/math/disjoint_set.h" #include "core/math/vector2.h" +#include "core/variant/dictionary.h" #include "core/variant/typed_array.h" #include "core/variant/variant.h" #include "core/version.h" @@ -57,8 +60,12 @@ #include "editor/import/resource_importer_scene.h" #include "scene/2d/node_2d.h" #include "scene/3d/camera_3d.h" +#include "scene/3d/mesh_instance_3d.h" #include "scene/3d/multimesh_instance_3d.h" #include "scene/animation/animation_player.h" +#include "scene/resources/importer_mesh.h" +#include "scene/resources/mesh.h" +#include "scene/resources/multimesh.h" #include "scene/resources/surface_tool.h" #include "modules/modules_enabled.gen.h" @@ -2101,7 +2108,7 @@ Error GLTFDocument::_serialize_meshes(Ref state) { Array meshes; for (GLTFMeshIndex gltf_mesh_i = 0; gltf_mesh_i < state->meshes.size(); gltf_mesh_i++) { print_verbose("glTF: Serializing mesh: " + itos(gltf_mesh_i)); - Ref import_mesh = state->meshes.write[gltf_mesh_i]->get_mesh(); + Ref import_mesh = state->meshes.write[gltf_mesh_i]->get_mesh(); if (import_mesh.is_null()) { continue; } @@ -2493,7 +2500,7 @@ Error GLTFDocument::_parse_meshes(Ref state) { Array primitives = d["primitives"]; const Dictionary &extras = d.has("extras") ?
