[1.7.10] Lighting issue with custom rendered blocks

[Delfil]

Hi,

 

The lighting on my custom rendered block is weird at a certain angle of view. It gets dark when I look up a bit. I made a short video where I show what happens. Does anyone have an idea about what goes wrong and/or how to solve it?

Version: 1.7.10 - 10.13.0.1180

 

Block:

Material: Material.rock

getRenderType() : -1

renderAsNormalBlock() : false

isOpaqueCube() : false

 

BlockBounds:

- minX: O

- minY: -2*O

- minZ: O

- maxX: I

- maxY: O

- maxZ: I

 

Constants:

O = 0.125

I = 1 - O

U = -0.5

D = -0.25

 

Render code in my render class, extending TileEntitySpecialRenderer:

	public void renderTileEntityAt(TileEntity _tile, double x, double y, double z, float d) {
	GL11.glPushMatrix();
	GL11.glTranslated(x, y + D, z);
	Tessellator t = Tessellator.instance;
	this.bindTexture(texture);
	t.startDrawing(GL11.GL_QUADS);
	// Top
	t.addVertexWithUV(O, U, O, 0, 0);
	t.addVertexWithUV(O, U, I, 0, 0.5);
	t.addVertexWithUV(I, U, I, 0.25, 0.5);
	t.addVertexWithUV(I, U, O, 0.25, 0);
	// Bottom
	t.addVertexWithUV(I, 0, O, 0.25, 0.5);
	t.addVertexWithUV(I, 0, I, 0.25, 1);
	t.addVertexWithUV(O, 0, I, 0, 1);
	t.addVertexWithUV(O, 0, O, 0, 0.5);
	// Side I
	t.addVertexWithUV(O, 0, O, 0.5, 0.5);
	t.addVertexWithUV(O, U, O, 0.5, 0.1875);
	t.addVertexWithUV(I, U, O, 0.75, 0.1875);
	t.addVertexWithUV(I, 0, O, 0.75, 0.5);
	// Side II
	t.addVertexWithUV(I, 0, I, 1, 0.5);
	t.addVertexWithUV(I, U, I, 1, 0.1875);
	t.addVertexWithUV(O, U, I, 0.75, 0.1875);
	t.addVertexWithUV(O, 0, I, 0.75, 0.5);
	// Side III
	t.addVertexWithUV(I, 0, O, 0.5, 1);
	t.addVertexWithUV(I, U, O, 0.5, 0.5 + 0.1875);
	t.addVertexWithUV(I, U, I, 0.75, 0.5 + 0.1875);
	t.addVertexWithUV(I, 0, I, 0.75, 1);
	// Side IIII
	t.addVertexWithUV(O, 0, I, 1, 1);
	t.addVertexWithUV(O, U, I, 1, 0.5 + 0.1875);
	t.addVertexWithUV(O, U, O, 0.75, 0.5 + 0.1875);
	t.addVertexWithUV(O, 0, O, 0.75, 1);
	t.draw();
	GL11.glPopMatrix();
}

You can just call GL11.glDisable(GL11.GL_LIGHTING) before your rendering then GL11.glEnable(GL11.GL_LIGHTING), that will remove the lighting for you block.

Hi

 

What is happening is that you're not properly setting up all the lighting for your block before rendering it.  So it is being affected by the last object that was rendered.

 

Look at a vanilla renderer to see what you're missing.

 

Typically for TileEntityRenderers you just need

            GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);  // full white

or

            tessellator.setColorOpaque(1, 1, 1);

 

You might also need

RenderHelper.disableStandardItemLighting();

[Delfil]

GL11.glEnable(GL11.GL_LIGHTING) / disable

&

RenderHelper.disableStandardItemLighting();

Work both to solve this problem.

 

Thank you!
