[1.8.9] [UNSOLVED] Renderer throws OpenGL errors

[Bektor]

Hi,

 

I'm currently having some problems with my render code for my block. I'm using Minecraft Forge 1.8.9.

The renderer draws sometimes blocks like the water in a different colour when I'm coming near to my own block and moving there a bit around.

 

Here is a picture of the problem:

 

And a picture which shows how everything is rendered when I'm a bit farer away. (just moved a bit away from my block)

 

The next point would be, when you are about 20 blocks from my block away it turns invisible, same goes when you are over the block (directly over it or farer away).

It does not turn complete invisible at once, it's goes more that part of part of the block are turning invisible.

 

Here is my TileEntityPortalRenderer:

@SideOnly(Side.CLIENT)
public class TileEntityPortalRenderer extends TileEntitySpecialRenderer<TileEntityPortal> {
    
    public static int sphereIDOutside;
    public static int sphereIDInside;
    
    @Override
    public void renderTileEntityAt(TileEntityPortal tileEntity, double posX, double posY, double posZ, float partialTicks, int destroyStage) {
        GlStateManager.pushMatrix(); // store the transformation 
        GlStateManager.translate(posX, posY, posZ); // set viewport to tile entity position to render it
        
        /* ============ Rendering Code goes here ============ */
        
        GlStateManager.translate(posX + 1f, posY - .6f, posZ + 1f);
        GlStateManager.enableBlend(); // enable rendering for transparency
        GlStateManager.depthMask(false);
        GlStateManager.blendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
        GlStateManager.color(1.f, 1.f, 1.f, 1.f);
        GlStateManager.callList(TileEntityPortalRenderer.sphereIDOutside);
        GlStateManager.callList(TileEntityPortalRenderer.sphereIDInside);
        
        //renderLight(posX, posY, posZ);
        GlStateManager.resetColor();
        GlStateManager.disableBlend();
        
        /* ============ Rendering Code stops here =========== */
        
        GlStateManager.popMatrix(); // restore the transformation, so other renderer's are not messed up
    }
    
    public static void createSphere() {
        Sphere sphere = new Sphere();
        sphere.setDrawStyle(GLU.GLU_FILL); // fill as a solid
        sphere.setTextureFlag(true);
        sphere.setNormals(GLU.GLU_SMOOTH); // smooth everything
        
        // First make the call list for the outside of the sphere
        sphere.setOrientation(GLU.GLU_OUTSIDE);
        TileEntityPortalRenderer.sphereIDOutside = GL11.glGenLists(1);
        // Create a new list to hold our sphere data
        GL11.glNewList(TileEntityPortalRenderer.sphereIDOutside, GL11.GL_COMPILE);
        // binds the texture
        ResourceLocation resource = new ResourceLocation(Constants.MOD_ID + ":" + "textures/entities/sphere.png");
        Minecraft.getMinecraft().getTextureManager().bindTexture(resource);
       
        sphere.draw(1.2f, 32, 32);
        GL11.glEndList();
        
        // Make the call list for the inside of the sphere
        sphere.setOrientation(GLU.GLU_INSIDE);
        TileEntityPortalRenderer.sphereIDInside = GL11.glGenLists(1);
        // Create a new list to hold our sphere data
        GL11.glNewList(TileEntityPortalRenderer.sphereIDInside, GLU.GLU_INSIDE);
        Minecraft.getMinecraft().getTextureManager().bindTexture(resource);
        
        sphere.draw(1.2f, 32, 32);
        GL11.glEndList();
    }
}

 

My init method in the ClientProxy which get's called at the end of the init method in the main class:

    @Override
    public void init() {
        super.init();
        
        TileEntityPortalRenderer.createSphere();
    }

 

Here are my json files:

blockstates

{
    "variants": {
        "normal": { "model": "primevalforest:portal" }
    }
}

 

block

{
"parent": "block/generated",
"textures": {
	"cross": "primevalforest:blocks/portal"
}
}

 

item

{
    "parent": "builtin/generated",
    "textures": {
        "layer0": "primevalforest:blocks/portal"
    },
    "display": {
        "thirdperson": {
            "rotation": [ -90, 0, 0 ],
            "translation": [ 0, 1, -3 ],
            "scale": [ 0.55, 0.55, 0.55 ]
        },
        "firstperson": {
            "rotation": [ 0, -135, 25 ],
            "translation": [ 0, 4, 2 ],
            "scale": [ 1.7, 1.7, 1.7 ]
        }
    }
}

 

I hope someone can help me.

 

Thx in advance.

Use an OBJ model both of these problems will be solved.

Unless you need it to do special stuff.

I might be using obj's in the future, but this problem got my interest and I want to know what's wrong there at any price. ^^

Why do I want to fix this problem at any cost: because of all the OpenGL error's I'm getting and to fix them might help me also

to better understand what's going on and how to fix it if I might get such errors outside of Minecraft, too.

 

So I tracked down the issue yet a bit:

 

// Make the call list for the inside of the sphere
        sphere.setOrientation(GLU.GLU_INSIDE);
        TileEntityPortalRenderer.sphereIDInside = GL11.glGenLists(1);
        // Create a new list to hold our sphere data
        GL11.glNewList(TileEntityPortalRenderer.sphereIDInside, GLU.GLU_INSIDE);
        Minecraft.getMinecraft().getTextureManager().bindTexture(resource);
        
        sphere.draw(1.2f, 32, 32);
        GL11.glEndList();

So, as seen above, removing this lines of code for the inner sphere removes the issue:

[Client thread/ERROR]: @ Post render

[Client thread/ERROR]: 1280: Invalid enum

[Client thread/ERROR]: ########## GL ERROR ##########

 

Now I've got only this code left in the createSphere method. I also removed the GlStateManager.color and GlStateManager.resetColor calls in renderTileEntityAt.

    public static void createSphere() {
        Sphere sphere = new Sphere();
        sphere.setDrawStyle(GLU.GLU_FILL); // fill as a solid
        sphere.setTextureFlag(true);
        sphere.setNormals(GLU.GLU_SMOOTH); // smooth everything
        
        // First make the call list for the outside of the sphere
        sphere.setOrientation(GLU.GLU_OUTSIDE);
        TileEntityPortalRenderer.sphereIDOutside = GL11.glGenLists(1);
        // Create a new list to hold our sphere data
        GL11.glNewList(TileEntityPortalRenderer.sphereIDOutside, GL11.GL_COMPILE);
        // binds the texture
        ResourceLocation resource = new ResourceLocation(Constants.MOD_ID + ":" + "textures/entities/sphere.png");
        Minecraft.getMinecraft().getTextureManager().bindTexture(resource);
       
        sphere.draw(1.2f, 32, 32);
        GL11.glEndList();
}

 

So now I'm getting a new error. This error does not happen on start up, it happens only when the block is drawn:

[Client thread/ERROR]: ########## GL ERROR ##########

[Client thread/ERROR]: @ Post render

[Client thread/ERROR]: 1281: Invalid value

 

So something I did or a class I'm using for it is heavily broken. Any ideas what the error could be?

 

Thx in advance.
