[1.15.2] Problems rendering a block

[xX_deadbush_Xx]

Hello,

I'm having a render problem with a block... when you look at the top from a very low angle you can see through the top of my block: https://imgur.com/a/VUA2dnV.

In the image you can see that the purple symbol on the top is still visible. This is because it sits on a different quad than the rest of the blocks top.

there is a square with this purple symbol with zero thickness 0.1 pixels above the top of the block. I'm doing this because the symbol gets rendered at full brightness using IBakedModel (This is why it seems like its glowing).

I have set the rendertype for the entire block to translucent because the square has zero alpha pixels and 20 alpha pixels.

 

Maybe it has something to do with me setting the render type of the block to translucent? I only really need this one quad with the symbol to be rendered translucent,

is it possible to only render a single quad translucent and the rest solid?

Howdy

 

Yeah it could be related to that.

It is possible to render one quad translucent and the rest solid using a forge multilayer block.

You could look at this working example here:

I have tried the multi layer model but it wont render the translucent part... The solid part is there though

"translucent": {
    "textures": {
      "3": "witchcraftmod:blocks/modelled/ritual_stone/4"
    },
      "elements": [
        {
          "from": [3, 12.1, 3],
          "to": [13, 12.1, 13],
          "faces": {
            "north": {"uv": [0, 0, 8, 0], "texture": "#3"},
            "east": {"uv": [0, 0, 8, 0], "texture": "#3"},
            "south": {"uv": [0, 0, 8, 0], "texture": "#3"},
            "west": {"uv": [0, 0, 8, 0], "texture": "#3"},
            "up": {"uv": [0, 0, 16, 16], "texture": "#3"},
            "down": {"uv": [0, 0, 8, 8], "texture": "#3"}
          }
        }
      ]
  }

This is the translucent part, in the game its just not there at all  The texture is definitely correct though

I'm think you might need to use

RenderTypeLookup.setRenderLayer(youblock, RenderType.getTranslucent());

Try this:

 

  // does the Glass Lantern render in the given layer (RenderType) - used as Predicate<RenderType> lambda for setRenderLayer
  public static boolean isGlassLanternValidLayer(RenderType layerToCheck) {
    return layerToCheck == RenderType.getCutout() || layerToCheck == RenderType.getTranslucent();
  }

It's still not putting the translucent texture onj the block... It does work on the blockitem though. I have tried only having it render the translucent part and that worked so it seems like the block cant have more than one RenderType at once... Any other ideas? If nothing works i will try using a TESR

Blocks can have more than one render layer. Have you tried TheGreyGhost’s solution?

Yes but it is still not rendering the translucent part on the block (on the item it works for some reason)

Please post your code.

Model json:

https://pastebin.com/t0GwXURU

RenderType:

//in client setup
RenderTypeLookup.setRenderLayer(ModBlocks.RITUAL_STONE.get(), RenderHelper::isSolidOrTranslucent);

//in RenderHelper
public static boolean isSolidOrTranslucent(RenderType layerToCheck) {
	return layerToCheck == RenderType.getSolid() || layerToCheck == RenderType.getTranslucent();
}

Is there anything else I need to do?

Hi

BTW your translucent texture should only have the up face, and none of the others on that element.

 

If it renders translucent in item but not block, it's almost certainly a renderlayer problem.  Are you sure the setRenderLayer is being executed and the RITUAL_STONE is correct?

 

What happens if you swap the order of translucent and solid?  It shouldn't matter, but it might show up  a subtle problem in your json.

You could consider simplifying your model to two simple elements then putting a breakpoint into MultiLayerModel.Loader to see whether your json file is being parsed as you expect

You could try putting a breakpoint into isSolidOrTranslucent and seeing if it's called when you place your block into the world; alternatively in ChunkRenderDispatcher::compile with a conditional breakpoint, or in MultiLayerModel::getQuads to see whether the quads are being rendered (and you just can't see them). 

 

Painful trial and error was the only way that worked for me unfortunately

Okay I think I just figured out what the problem is. As I said I'm rendering the top texture at full brightness and appearently that works differently for MultiLayerModels. I will see if I can figure out how to make it work for MultiLayerModels too. Thank you for your help
