[1.7.10] Custom Tile Entity Renders with Different Shade than Original Texture


Recommended Posts

Whenever I create a Tile Entity and render it with TileEntitySpecialRenderer, the resultant model is always a different shade than the original texture that is used.

 

Here is an example.  In this case, i'm using OpenGL to render the block with the standard stone texture with an custom overlay for the ore.  For this instance I followed this thread:

http://www.minecraftforge.net/forum/index.php/topic,26033.msg132818.html#msg132818.

 

However, this did not solve my issue.  This also happens when I use a Techne generated model.

(My blocks have the red arrows pointing at them)

 

Here is TESR code I used for this example

public class OreTileEntityRenderer extends TileEntitySpecialRenderer {

private ResourceLocation blockTexture;
private ResourceLocation oreTexture;

/**
 * 
 * @param blockTexture
 * @param oreTexture
 */
public OreTileEntityRenderer(String blockTexture, String oreTexture ) {
	setBlockTexture(new ResourceLocation(blockTexture));
	setOreTexture(new ResourceLocation(oreTexture));
}

@Override
public void renderTileEntityAt(TileEntity tileEntity, double x, double y, double z, float scale) {
	int au = 0;
	int av = 0;
	int bu= 0;
	int bv = 1;
	int cu = 1;
	int cv = 1;
	int du = 1;
	int dv = 0;

	// bind the texture to use
	Minecraft.getMinecraft().renderEngine.bindTexture(getBlockTexture());

	// set up GL
	GL11.glPushMatrix();
	GL11.glTranslated(x, y, z);
	GL11.glPushAttrib(GL11.GL_ALL_ATTRIB_BITS);
	GL11.glEnable(GL11.GL_ALPHA_TEST);
	GL11.glDisable(GL11.GL_LIGHTING);

	Tessellator t = Tessellator.instance;

	for (int i = 0; i <=1; i++) {
		if (i > 0) {
			Minecraft.getMinecraft().renderEngine.bindTexture(getOreTexture());
			GL11.glEnable(GL11.GL_BLEND);
			GL11.glDepthMask(false);
			GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);		
			GL11.glAlphaFunc(GL11.GL_LESS, 1.0f);
		}

		// draw the opaque block
		t.startDrawingQuads();
		t.setColorOpaque_F(1.0F, 1.0F, 1.0F);
		// add the vertices
		t.addVertexWithUV(0, 0, 0, cu, cv); //A:c
		t.addVertexWithUV(0, 1, 0, du, dv); //B:d
		t.addVertexWithUV(1, 1, 0, au, av); //C:a
		t.addVertexWithUV(1, 0, 0, bu, bv); //D:b
		t.draw();

... // removed rest for brevity 

 

Any help is much appreciated.

 

UPDATE:  And light sources change the color when other blocks (stone) aren't.  This there a block variable I have to set?  This doesn't seem like a rendering problem.

Hi

 

You haven't set the brightness on the tessellator so the blocklight/skylight settings are ignored.  You also haven't done direction-dependent brightness on the faces.

 

This link might be helpful.  It's basically the same as for 1.7.10.

http://greyminecraftcoder.blogspot.com.au/2014/12/lighting-18.html

 

Have a look in RenderBlocks.renderStandardBlockWithColorMultiplier(), the key parts are

 

        float f3 = 0.5F;

        float f4 = 1.0F;

        float f5 = 0.8F;

        float f6 = 0.6F;

for use with face-dependent brightness eg

            tessellator.setColorOpaque_F(f10, f13, f16);

 

and the setBrightness

eg

            tessellator.setBrightness(block.getMixedBrightnessForBlock(this.blockAccess, x, y- 1, z));  // for the bottom face

            tessellator.setBrightness(block.getMixedBrightnessForBlock(this.blockAccess, x, y+ 1, z));  // for the top face

etc

(Notice that for solid blocks, you have to get the mixedbrightness from the adjacent block.  The mixed brightness of the solid block itself is 0).

Thanks TheGreyGhost,

 

However, following the code for the call

 

tessellator.setBrightness(block.getMixedBrightnessForBlock(this.blockAccess, x, y- 1, z))

 

requires that I pass something that implements IBlockAccess into getMixedBrightnessForBlock().  A TESR doesn't provide that property.  How else can I obtain an IBlockAccess object?

 

Thanks

World implements IBlockAccess.

Your TESR should have access to your TE which has a worldObj

Ok,

I tried doing as you instructed.  You can see the light source affect the block coloring in a chunky gradient fashion, however, they still look nothing like the original stone block. ie not smooth gradient and different color.

 

(I removed my ore overlay to make it clearer)

My blocks are highlighted in red, vanilla in blue.

Its because you aren't using smooth lighting code.  You're using the fast lighting code (if you turn off smooth lighting in the options I'll bet you can't tell the difference).

 

And heads up: smooth lighting code is a bitch.  I gave up on it when I was doing whateverthehell it was that I was doing that was similar.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Totally right! I turned off smooth lighting and everything looked the way I expected.  I guess I'll just go with it as is, as this is only a minor mod and I don't want to dump that much time into it.  Though smooth lighting would've been nice.

Hi

 

You could perhaps consider using an ordinary block for the base texture, with smooth lighting, and using your TESR just to draw the overlay using the block brightness (like you're doing now).  The Beacon does this, for example.

That way vanilla will do all the hard work for you on the stone texture.  Your TESR won't have smooth lighting but because it's not continuous like the background is, you probably won't be able to tell the difference.

I understand the gist of what your suggesting, but I'm not sure how I would accomplish this. (I'm not in a place where I can test it at the moment).  Will my block render itself in the world before my TESR executes()? ie. if i used an empty render() method the TESR would I see the plain block?

 

Or are you suggesting I somehow use the code the renderBlockBeacon() method in the RenderBlocks class? All of it's code is reliant on other methods with RenderBlocks which I'd have to copy or extend.

Ok, I did as you suggested. Make the block render as a normal block and had the TESR render only the overlay with brightness.

It works somewhat... The block renders, but the overlay flickers like crazy unless you stare at one position and not all the overlays are rendered in their entirety.

 

Ex.

Thats called Z-fighting (i think)

 

Yup, Z-fighting.  And by "slightly" an offset of 0.01 is usually enough.

Indeed, Z-fighting was the culprit.  It all works swimmingly now.  Thanks to all for helping me walk through this.

 

The overlay ore texture on top of the default/resourcepack block texture looks much better than my static ore block.  It can blend in with whatever resourcepack so much easier now.

 

Thanks again!
