When binding texture and drawing quad it appears to be much darker than texture file. I tried to disable lightning, color texture white, add additional brightness through glTexEnv, but nothing changed. Example code:

[embed=425,349]

import net.minecraft.client.renderer.GlStateManager;

import net.minecraft.client.renderer.Tessellator;

import net.minecraft.client.renderer.VertexBuffer;

import net.minecraft.client.renderer.tileentity.TileEntitySpecialRenderer;

import net.minecraft.client.renderer.vertex.DefaultVertexFormats;

import net.minecraft.tileentity.TileEntity;

import net.minecraft.util.ResourceLocation;

import org.lwjgl.opengl.GL11;

 

public class MultiBlockTESR extends TileEntitySpecialRenderer<TileEntity> {

 

    public static ResourceLocation TEXTURE = new ResourceLocation("textures/blocks/anvil_base.png");

 

    @Override

    public void renderTileEntityAt(TileEntity te, double x, double y, double z, float partialTicks, int destroyStage) {

        GlStateManager.pushMatrix();

 

        //GlStateManager.disableLighting(); //Doesn't work

        //RenderHelper.disableStandardItemLighting(); //Doesn't work too

 

        GlStateManager.translate(x, y, z);

        GlStateManager.disableCull();

 

        bindTexture(TEXTURE);

       

        Tessellator tessellator = Tessellator.getInstance();

        VertexBuffer vertexBuffer = tessellator.getBuffer();

 

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

        vertexBuffer.pos(0, 0, 0).tex(0, 0).endVertex();

        vertexBuffer.pos(0, 1, 0).tex(0, 1).endVertex();

        vertexBuffer.pos(1, 1, 0).tex(1, 1).endVertex();

        vertexBuffer.pos(1, 0, 0).tex(1, 0).endVertex();

 

        tessellator.draw();

        GlStateManager.popMatrix();

    }

}

Try setting the color to 0xffffff or ARGB 1,1,1,1 anywhere before you start drawing.

Or try enabling texture2d.

 

See if what works

Both have no effect.

I have the same issues do you have any new clue about the issue?

GL11.enable/disableLighting();

allready tried with GlStateManager.disableLighting() or GL11.glDisable(GL11.GL_LIGHTING), it make the quad rendered a bit less dark but still really dark.

Try making the Block letting Light through, like glass.

The problem is with isOpaqueCube in the block class.

When you set it to true it make the things you render in theTESR dark. Its linked to ambient occlusion.

Setting it to false make the TESR  fine but the problem is that i want my block to be opaque for it to not let light pass through.

Just found a solution :

int li = t.getWorld().getCombinedLight(t.getPos(), 15728640);
int i1 = li % 65536;
int j1 = li / 65536;
OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit, (float) i1, (float) j1);

With the opaque set to true so it doesnt let the light pass through

Why are you making a tesr?

To render dynamic fluid level

Is it animated/changing every frame?

If not use a normal model.
