Assimp static Meshes Black Screen

[simagdo]

Hey,

i recently asked for help with the Chapter for normal mapping. Now i have the same error that i see a black screen when i execute my program. I followed your tutorial and i got stuck in the StaticMeshesLoader. When i execute the Program, i got the following error:
java.lang.Exception: Error loading model at de.simagdo.engine.loaders.assimp.StaticMeshesLoader.load(StaticMeshesLoader.java:32) at de.simagdo.engine.loaders.assimp.StaticMeshesLoader.load(StaticMeshesLoader.java:21) at de.simagdo.game.DummyGame.init(DummyGame.java:55) at de.simagdo.engine.GameEngine.init(GameEngine.java:46) at de.simagdo.engine.GameEngine.run(GameEngine.java:33) at de.simagdo.system.MainComponent.main(MainComponent.java:21)

I fixed it by using the following code:
resourcePath = StaticMeshesLoader.class.getClassLoader().getResource(resourcePath).getPath(); if (resourcePath.startsWith("/")) resourcePath = resourcePath.substring(1);

After that i can finally start the Program without any error, but the only thing i see is a black window. I started again by using the source i saved from chapter 26, without any luck at all ;/
This is my current Window:

I don't know where the error occurs, i have already debugged the part where i am loading the GameItems. Parallel to that i debugged your source and i got the same results.

Currently I am using Java 13 and OpenGL 3.1.2

I'll have a look at it. Unfortunately, Renderdoc is crashing lately on my computer, so it may take some time.

Hi,

I thnik the problem is that you are not setting the material uniform while rendering. This makes some values to be 0 (such us the ambient colour), which makes the nice black window.

In the renderNonInstancedMeshes method, you removed the following line just after the for loop:

sceneShaderProgram.setUniform("material", mesh.getMaterial());

Please add this line and let me know if this solves your problem.

Thank you very much for your fast response. This was exactly the problem. After i added this line, everything works as it should.
