I have a custom model that has a semi-transparent texture, but for some reason the model randomly flashes white. Why is this? Heres a imgur album showing what happens:

And heres my render code:

 

public class CrystalRender extends TileEntitySpecialRenderer {

ResourceLocation modelTexture = new ResourceLocation(EnchantedAura.modid + ":textures/blocks/AuraCrystal.png");
ResourceLocation objModelLocation = new ResourceLocation(EnchantedAura.modid + ":models/Crystal.obj");
    IModelCustom model = AdvancedModelLoader.loadModel(objModelLocation);

@Override
public void renderTileEntityAt(TileEntity tile, double posX, double posY, double posZ, float thing) {

	int rot = 1;
	float Xoffset = 0;
	float Yoffset = 0;
	float Zoffset = 0;

	if (!(tile.getWorldObj() == null)) {
		rot = tile.getWorldObj().getBlockMetadata(tile.xCoord, tile.yCoord, tile.zCoord);
	}

	if (rot == 0) {
		Yoffset = 0.5F;
	} else if (rot == 1) {
		Yoffset = -0.5F;
	} else if (rot == 2) {
		Zoffset = 0.5F;
	} else if (rot == 3) {
		Zoffset = -0.5F;
	} else if (rot == 4) {
		Xoffset = 0.5F;
	} else if (rot == 5) {
		Xoffset = -0.5F;
	}

	GL11.glPushMatrix();
	GL11.glColor3f(1.0F, 1.0F, 1.0F);
	GL11.glTranslated(posX + Xoffset + 0.5F, posY + Yoffset + 0.5F, posZ + Zoffset + 0.5F);

	if (rot == 0) {
		GL11.glRotatef(180.0F, 0.0F, 0.0F, 1.0F);
	} else if (rot == 2) {
		GL11.glRotatef(-90.0F, 1.0F, 0.0F, 0.0F);
	} else if (rot == 3) {
		GL11.glRotatef(90.0F, 1.0F, 0.0F, 0.0F);
	} else if (rot == 4) {
		GL11.glRotatef(90.0F, 0.0F, 0.0F, 1.0F);
	} else if (rot == 5) {
		GL11.glRotatef(-90.0F, 0.0F, 0.0F, 1.0F);
	}

	if (tile.getWorldObj() != null) {
		GL11.glScalef(2F, 2F, 2F);
	} else {
		GL11.glScalef(3.5F, 3.5F, 3.5F);
	}

	FMLClientHandler.instance().getClient().renderEngine.bindTexture(modelTexture);

	GL11.glPushAttrib(GL11.GL_ENABLE_BIT);
	GL11.glDisable(GL11.GL_CULL_FACE);
	GL11.glEnable(GL11.GL_BLEND);

	model.renderAll();

	GL11.glDisable(GL11.GL_BLEND);
	GL11.glPopAttrib();
	GL11.glPopMatrix();

}

}

Bump

Never mind, I figured it out. All I had to do was add

GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);

before

GL11.glEnable(GL11.GL_BLEND);
