The 3D model is red or not displayed at all

[10100010010001001010]

In tests, all 3D models are displayed correctly, but in my own project "orc.c3b" without a texture, and "boss1.obj" not displayed at all. Perhaps I missed something in the sample code from the tests, but I double-checked and didn’t notice anything like that.

my update method:

case ExampleGameState::init:
{
    _gameState = ExampleGameState::update;

    auto s = Director::getInstance()->getWinSize();

    auto enemy = ax::MeshRenderer::create("orc.c3b");
         enemy->setPosition3D(Vec3(0, 0, 0));
         enemy->setCameraMask(2);
         addChild(enemy);

    auto boss = ax::MeshRenderer::create("boss.obj");
         boss->setPosition3D(Vec3(20.0f, 0, 0));
         boss->setTexture("boss.png");
         boss->setCameraMask(2);
         addChild(boss);

    auto light = ax::PointLight::create(Vec3(0, 0, 20.0f), Color3B(150.0f, 50.0f, 250.0f), 100.0f);
         addChild(light);

    auto camera = Camera::createPerspective(90, s.width / s.height, 1, 1000);
         camera->setCameraFlag(CameraFlag::USER1);
         camera->setPosition3D(Vec3(10.0f, 0.0f, 130.0f));
         addChild(camera);
         camera->lookAt(boss->getPosition3D());

    break;
}

What is inside the Contents directory of your project? If the orc.c3b is not showing the texture, then it may be missing from your project. The file is named monguger.tga, and you can find it in the same folder where you copied orc.c3b from (tests\cpp-tests\Content\MeshRendererTest).

thanks, it works, I did not know that this was a texture file. c3b, c3t - what are these extensions? I previously tried to find a similar extension, but didn’t find anything relevant

And as i understand for my own 3d models i should use fbx-conv from cocos, right ?

I'm not sure if you need to use the c3t/c3b format, as the engine does seem to support the OBJ format.

thanks for reply, i saw this info about that formats, but it too superficial. I would like to read about the file format in more detail, but unfortunately the creators of cocos did not make any documentation for the format

Open the .c3t file in a text editor, since it is in plain text format. It should give you some insight regarding the format.
