So i was trying to update my stairs from 1.8 but seems something has changed in rendering. This is how they looks if placed upside

And this is my stairs code, i've tried adding the isOpaqueCube function but it seems to change nothing

package com.mineworld.blocks;

import com.mineworld.core.MWTabs;

import net.minecraft.block.Block;
import net.minecraft.block.BlockStairs;
import net.minecraft.block.SoundType;
import net.minecraft.block.material.Material;
import net.minecraft.block.state.IBlockState;
import net.minecraft.util.EnumBlockRenderType;
import net.minecraft.util.EnumFacing;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.IBlockAccess;

public class BlockStairsMW extends BlockStairs{

public BlockStairsMW(Block block) {
	this(block.getDefaultState());
}

public BlockStairsMW(Block block, int meta) {
	this(block.getStateFromMeta(meta));
}


public BlockStairsMW(IBlockState state) {
	super(state);
	this.setHardness(3.0F);
	this.setResistance(5.0F);
	if(state.getBlock().getMaterial(state).equals(Material.wood))
		this.setStepSound(SoundType.WOOD);
	else
		this.setStepSound(SoundType.METAL);
	this.setCreativeTab(MWTabs.tabBlock);
	this.setLightOpacity(0);
}

@Override
public boolean isOpaqueCube(IBlockState state) {
	return false;
}
}

Try isFullCube

Doesn't work. Also slabs has the same problem

Hi

 

I haven't started with 1.9 yet; I would suggest you should look at the vanilla stairs and/or slabs Block to see how they're different from your block; and how they're different to stairs from vanilla 1.8

You should probably also look in the json model files for anything different.

Appearently from rendering side nothing has changed in  both json files and classes

So upgrading Forge to a newer version (when available) will sove the problem? Good to know And thanks for response
