jMonkeyBuilder: Bugs

javasabr · June 9, 2018, 10:35am

could you try this build, please?

I’m getting a similar problem with the exact Xorg error code, but using bspwm. (which I believe it’s not too different to awesome WM)

However, when I debugged the editor, the crash seemed to happen randomly on LwjglWindow.java (from jME) inside the “update loop”. Sometimes it only takes 3 cycles to crash, but other times it was able to go through 20 cycles.

I finally have the time to test more about this problem, so I’ll try both your workaround and a simple jME test case now.

Thank you for the quick reply!
Sadly this doesn’t work either. The output seems to be the same:

It seems a bug with glfw back-end of lwjgl3, I will try to update these libraries.

@Toboi @Ev1lbl0w
Could you try this build, please?

I have updated LWJGL to 3.1.6

Toboi · June 10, 2018, 12:22am

Still no luck… It gives me the same error.

I’m having trouble loading any scene that has a PBR tree on version 1.8.0 - if the scene contains any tree I’ve made since the new version, then JMB crashes without any error, but only if the tree has a leaf material applied.

When I try to make a new SimarborealTree project in JMB, then I also get the following error as well as a JMB crash when I try to apply a leaf material that I have created from the old version.

javasabr · June 10, 2018, 11:17am

Do you know what is it?

MatDefs/FragScattering.glsllib

javasabr · June 10, 2018, 12:52pm

Could you try to launch any jME hello example using lwjgl3 as back-end, please?

b00n · June 10, 2018, 5:48pm

this is the atmospheric shader from @pspeed

javasabr · June 10, 2018, 6:49pm

You need to define a folder with your custom libraries in Settings:

because the MatDefs/FragScattering.glsllib isn’t part of jME libraries.

yaRnMcDonuts · June 10, 2018, 7:42pm

Ohh I was using one of my old leaf materials from the original SimArboreal editor, rather than your PBR implementation for JMB.

I created a new Tree Project in JMB and I’m trying to get the embedded PBR leaf material to work, but for some reason the leaves are always black by default, and I can’t seem to get the proper colors from the albedo texture to appear

javasabr · June 10, 2018, 7:44pm

You can create not PBR tree as well, but what about your problem… which OpenGL version do you use in Settings of jMB?

yaRnMcDonuts · June 10, 2018, 7:46pm

It says its using OpenGl 3.3 with core profile.

I should also note that the only way I can get the leaves to change from black is by altering the Emissive Color. But it doesn’t seem like I can get the Albedo colors to show through.

yaRnMcDonuts · June 14, 2018, 5:52am

I am not sure if you’ve had time to look into it yet, but I had some time to investigate this error with the PBR Leaves showing up black, and it looks like the problem is occurring where the directDiffuse vec3 variable is being computed

I was confused at first, because your PBR Bark shader and your PBR Leaf shader both use the same reference to PBRLighting.frag. But I found the problem lies in the value being assigned to directDiffuse in this part of the fragment shader

    vec3 directDiffuse;
    vec3 directSpecular;
    
    float hdotv = PBR_ComputeDirectLight(normal, lightDir.xyz, viewDir,
                        lightColor.rgb, fZero, Roughness, ndotv,
                        directDiffuse,  directSpecular);
// the value being assigned to directDiffuse is always (0, 0, 0), causing leaves to appear un-lit

    // directDiffuse = vec3(1.0, 1.0, 1.0);    // <- set a fixed value here for testing. un-commenting this line will cause leaves to light up very bright

    vec3 directLighting = diffuseColor.rgb *directDiffuse + directSpecular;

    gl_FragColor.rgb += directLighting * fallOff;
}

I tried looking at the difference in the .vert file for the Bark shader compared to the Leaves, but I could not figure out the underlying source of the problem.

I’m going to look at this problem after when I finish some refactoring in 1.9.0 I’m working on reducing startup time of jMB now.

Toboi · June 14, 2018, 10:26am

I can run the examples with lwjgl3 using openjdk 8, but using jdk 9 or 10 I get the following error:

so, could you test jMB 1.7.2, please? it uses java8

It gives me the same crash on startup:

Could you try to use openjdk8 to run jMB 1.7.2?
