How can I remove or disable the color being darkened by idk what? Like, I set it to red but it is a dark color red instead of just bright red. Also, it becomes bright red when I don't look at the block and are a few blocks away from it.

That would be lighting.

I tried a lot but could not replicate the issue. I do have an idea of where it could be coming from. The lightmap coordinates might be wrong. You will need to manualy set them to something like 240, 240 with OpenGlHelper::setLightmapTextureCoords to achieve full brightness.

I do not really know if you 'need to' but you 'should' do it. You can get the current lightmap coordinates at OpenGlHelper.lastBrightnessX/OpenGlHelper.lastBrightnessY. Idealy you would just put you lightmap coordinates directly into the BufferBuilder by specifying a format that supports them though and using BufferBuilder::lightmap for each vertex.

So this? 

public class AMUtils {

lightmap is a vertex property. You can't just call it for a buffer as a whole and call it a day. This will not work.

POSITION_TEX_LMAP_COLOR

If you are specifying position, texture, lightmap and color you need to provide them. You are not providing the uvs.

 

2 minutes ago, Kokkie said:

bb.begin(GL11.GL_LINE_STRIP, DefaultVertexFormats.POSITION_TEX_LMAP_COLOR);

RenderGlobal.drawBoundingBox(bb, minX, minY, minZ, maxX, maxY, maxZ, 1, 0, 0, 1);

RenderGlobal::drawBoundingBox is written to only handle position and color. You can start the drawing with any other format and it will not work bacause it is not coded to. You need to provide your own code for doing that. This is the reason I originaly suggested using OpenGlHelper::setLightmapTextureCoords.

You still have this call. Remove it.

You are not specifying the uvs here.

pos, color, lightmap, tex != pos, tex, lightmap, color. Ordering matters. Same applies to the code you've copied from RenderGlobal.

Almost. This is correct for the most part but there is one small, illusive and obscure issue. The BufferBuilder::color method has 2 overloads - 1 that uses 4 floats of [0 - 1] ranges and 1 that uses 4 integers of [0 - 255] ranges. As integer is the default number in java when you pass in a number without specifying it's type(like you are doing everywhere with color(1, 0, 0, 1)) it is assumed to be an integer. So the method with integers as params gets invoked instead of the one with floats and... well, you are passing 1 as alpha which considering an integer range of that method is practicaly invisible. You need to specify at least one number as a float so the correct method is chosen.

 

In my original example I use

color(1, 0, 0, 1F)

Note the 1F at the end. By passing that number as a float I force the correct method to be chosen.
