Hey all, first time posting. I'm having difficulty with rendering a simple cube in a tileentities TESR, I'm not great with rendering in general, so any help would be appreciated.

EDIT: I should note that I have simplified this code to be as bare bones as it can be, until I can get the cube to render correctly.

https://github.com/The-PurpleOrange/Arcanacraft/blob/master/src/main/java/com/tyhone/arcanacraft/client/render/tesr/RenderTileEntityJar.java
There's the offender

When using DefaultVertexFormats.BLOCK I get this, but with DefaultVertexFormats.POSITION I get a cube, but I cant control the rgba, and it randomly flickers and goes invisible. POSITION _COLOR does something similar to BLOCK as well

 

Heres the TESR code:

public void render(TileEntity te, double x, double y, double z, float partialTicks, int destroyStage, float alpha){
		TileEntityJar jar = (TileEntityJar) te;
		double fluidLevel = jar.getFluidLevel();
		double maxFluid = jar.getMaxFluid();
		String fluidType = jar.getFluidType();
		
		if(true){
			
			Tessellator tess = Tessellator.getInstance();
			BufferBuilder buffer = tess.getBuffer();
			
			GlStateManager.pushMatrix();

			//Render smooth stuff
		    RenderHelper.disableStandardItemLighting();
		    GlStateManager.enableBlend();
		    GlStateManager.blendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);

		    /*if(Minecraft.isAmbientOcclusionEnabled()) {
		      GL11.glShadeModel(GL11.GL_SMOOTH);
		    }
		    else {
		      GL11.glShadeModel(GL11.GL_FLAT);
		    }*/

		    GlStateManager.translate(x, y+1, z);
		    
			buffer.begin(GL11.GL_QUADS, DefaultVertexFormats.BLOCK);
			buffer.color(255, 0, 0, 255);

		    buildQuad(buffer, 0, 0, 0, 1, 1, 1, EnumFacing.DOWN);
		    buildQuad(buffer, 0, 0, 0, 1, 1, 1, EnumFacing.UP);
		    buildQuad(buffer, 0, 0, 0, 1, 1, 1, EnumFacing.NORTH);
		    buildQuad(buffer, 0, 0, 0, 1, 1, 1, EnumFacing.SOUTH);
		    buildQuad(buffer, 0, 0, 0, 1, 1, 1, EnumFacing.EAST);
		    buildQuad(buffer, 0, 0, 0, 1, 1, 1, EnumFacing.WEST);
		    
		    tess.draw();

		    GlStateManager.disableBlend();
		    GlStateManager.popMatrix();
		    RenderHelper.enableStandardItemLighting();
		}
	}

 

And here is buildQuad:

public static void buildQuad(BufferBuilder renderer, double x, double y, double z, double w, double h, double d, EnumFacing face) {

		double s = 0.1;
		double x1 = x + s;
		double x2 = x + w - s;
		double y1 = y + s;
		double y2 = y + h - s;
		double z1 = z + s;
		double z2 = z + d - s;

		switch(face) {
		case DOWN:
			renderer.pos(x1, y1, z1).endVertex();
			renderer.pos(x2, y1, z1).endVertex();
			renderer.pos(x2, y1, z2).endVertex();
			renderer.pos(x1, y1, z2).endVertex();
			break;
		case UP:
			renderer.pos(x1, y2, z1).endVertex();
			renderer.pos(x1, y2, z2).endVertex();
			renderer.pos(x2, y2, z2).endVertex();
			renderer.pos(x2, y2, z1).endVertex();
			break;
		case NORTH:
			renderer.pos(x1, y1, z1).endVertex();
			renderer.pos(x1, y2, z1).endVertex();
			renderer.pos(x2, y2, z1).endVertex();
			renderer.pos(x2, y1, z1).endVertex();
			break;
		case SOUTH:
			renderer.pos(x1, y1, z2).endVertex();
			renderer.pos(x2, y1, z2).endVertex();
			renderer.pos(x2, y2, z2).endVertex();
			renderer.pos(x1, y2, z2).endVertex();
			break;
		case WEST:
			renderer.pos(x1, y1, z1).endVertex();
			renderer.pos(x1, y1, z2).endVertex();
			renderer.pos(x1, y2, z2).endVertex();
			renderer.pos(x1, y2, z1).endVertex();
			break;
		case EAST:
			renderer.pos(x2, y1, z1).endVertex();
			renderer.pos(x2, y2, z1).endVertex();
			renderer.pos(x2, y2, z2).endVertex();
			renderer.pos(x2, y1, z2).endVertex();
			break;
		}
	}

SORRY FOR NECROING AN OLD THREAD!

If anyone wants examples of how to use DefaultVertexFormats.BLOCK look at net.minecraft.client.renderer.BlockFluidRenderer or

Spoiler

// debug quad
VertexBuffer.pos(0, 1, 0).color(0xFF, 0xFF, 0xFF, 0xFF).tex(0, 0).lightmap(240, 0).endVertex();
VertexBuffer.pos(0, 1, 1).color(0xFF, 0xFF, 0xFF, 0xFF).tex(0, 1).lightmap(240, 0).endVertex();
VertexBuffer.pos(1, 1, 1).color(0xFF, 0xFF, 0xFF, 0xFF).tex(1, 1).lightmap(240, 0).endVertex();
VertexBuffer.pos(1, 1, 0).color(0xFF, 0xFF, 0xFF, 0xFF).tex(1, 0).lightmap(240, 0).endVertex();

 

If anyone wants examples of how to use DefaultVertexFormats.POSITION_TEX look at net.minecraft.client.renderer.ItemRenderer or RenderTileEntityAlchemicArray.java

 

If anyone wants examples of how to use DefaultVertexFormats.POSITION_TEX_COLOR look at net.minecraft.client.renderer.RenderGlobal or ClientUtil.java

 

Examples for everything except block are pretty easy to find with your IDE's search
