[1.10.2] VertexBuffer / Tessellator

[COM8]

Hi, I'm trying to render a texture in a gui. I'm using the following method and everything renders just fine, but the texture is really dark. The lighting is not correct. Is there a way to fix this?

 

Tessellator tessellator = Tessellator.getInstance();
        VertexBuffer vertexbuffer = tessellator.getBuffer();
        vertexbuffer.begin(7, DefaultVertexFormats.POSITION_TEX);
        vertexbuffer.pos((double)(xCoord + 0.0F), (double)(yCoord + (float)maxV), 0).tex((double)((float)(minU + 0) * 0.00390625F), (double)((float)(minV + maxV) * 0.00390625F)).endVertex();
        vertexbuffer.pos((double)(xCoord + (float)maxU), (double)(yCoord + (float)maxV), 0).tex((double)((float)(minU + maxU) * 0.00390625F), (double)((float)(minV + maxV) * 0.00390625F)).endVertex();
        vertexbuffer.pos((double)(xCoord + (float)maxU), (double)(yCoord + 0.0F), 0).tex((double)((float)(minU + maxU) * 0.00390625F), (double)((float)(minV + 0) * 0.00390625F)).endVertex();
        vertexbuffer.pos((double)(xCoord + 0.0F), (double)(yCoord + 0.0F), 0).tex((double)((float)(minU + 0) * 0.00390625F), (double)((float)(minV + 0) * 0.00390625F)).endVertex();
        tessellator.draw();

 

Any help / information is appreciated.

You need to disable GL11.GL_LIGHTING, if I recall correctly.

Thanks for the fast reply!

I tried to disable it but nothing changes

 

GlStateManager.pushMatrix();
	GL11.glDisable(GL11.GL_LIGHTING);

        Tessellator tessellator = Tessellator.getInstance();
        VertexBuffer vertexbuffer = tessellator.getBuffer();
        vertexbuffer.begin(7, DefaultVertexFormats.POSITION_TEX);
        vertexbuffer.pos((double)(xCoord + 0.0F), (double)(yCoord + (float)maxV), 0).tex((double)((float)(minU + 0) * 0.00390625F), (double)((float)(minV + maxV) * 0.00390625F)).endVertex();
        vertexbuffer.pos((double)(xCoord + (float)maxU), (double)(yCoord + (float)maxV), 0).tex((double)((float)(minU + maxU) * 0.00390625F), (double)((float)(minV + maxV) * 0.00390625F)).endVertex();
        vertexbuffer.pos((double)(xCoord + (float)maxU), (double)(yCoord + 0.0F), 0).tex((double)((float)(minU + maxU) * 0.00390625F), (double)((float)(minV + 0) * 0.00390625F)).endVertex();
        vertexbuffer.pos((double)(xCoord + 0.0F), (double)(yCoord + 0.0F), 0).tex((double)((float)(minU + 0) * 0.00390625F), (double)((float)(minV + 0) * 0.00390625F)).endVertex();
        tessellator.draw();
        
        GlStateManager.popMatrix();

Then try specifying specific colors, using GlStateManager.color

Thank's it works!

Awesome!
