Hi, I have problem to draw texture overlay over block side. I am not familiar with OpenGL so I tried to look into other projects/mc source code, but without success. Currently I have this code in TER:

 

    private ResourceLocation texture = new ResourceLocation(Reference.MODID, "textures/block/machine_top.png");

    @Override
    public void render(BoilerTile tileEntityIn, double x, double y, double z, float partialTicks, int destroyStage) {
        GlStateManager.pushMatrix();

        bindTexture(texture);

        Tessellator tessellator = Tessellator.getInstance();
        BufferBuilder bufferbuilder = tessellator.getBuffer();

        bufferbuilder.begin(GL11.GL_QUADS, DefaultVertexFormats.POSITION_TEX);

        bufferbuilder.pos(x, y + 1.1, z + 1.0D).tex(0, 1).endVertex();
        bufferbuilder.pos(x + 1.0D, y + 1.1, z + 1.0D).tex(1, 1).endVertex();
        bufferbuilder.pos(x + 1.0D, y + 1.1, z).tex(1, 0).endVertex();
        bufferbuilder.pos(x, y + 1.1, z).tex(0, 0).endVertex();

        tessellator.draw();

        GlStateManager.popMatrix();
    }

 

Results in this (texture is too dark):

Can you please guide me how to draw texture overlay correctly?

I got it working

 

    private ResourceLocation texture = new ResourceLocation(Reference.MODID, "textures/block/fluid_pipe.png");

    @Override
    public void render(BoilerTile tileEntityIn, double x, double y, double z, float partialTicks, int destroyStage) {
        GlStateManager.pushMatrix();
        GlStateManager.translated(x, y, z);

        Tessellator tessellator = Tessellator.getInstance();
        BufferBuilder bufferbuilder = tessellator.getBuffer();

        bindTexture(texture);
        RenderHelper.disableStandardItemLighting();
        GlStateManager.blendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
        GlStateManager.enableBlend();
        GlStateManager.disableCull();

        bufferbuilder.begin(GL11.GL_QUADS, DefaultVertexFormats.POSITION_TEX);
        bufferbuilder.pos(0, 1.1, 1).tex(0, 1).endVertex();
        bufferbuilder.pos(1, 1.1, 1).tex(1, 1).endVertex();
        bufferbuilder.pos(1, 1.1, 0).tex(1, 0).endVertex();
        bufferbuilder.pos(0, 1.1, 0).tex(0, 0).endVertex();

        tessellator.draw();

        GlStateManager.enableCull();
        GlStateManager.disableBlend();
        RenderHelper.enableStandardItemLighting();

        GlStateManager.popMatrix();
    }

 

and in Block class extends this:

    @Override
    public BlockRenderLayer getRenderLayer() {
        return BlockRenderLayer.CUTOUT_MIPPED;
    }
