Hello. I want to archive a block which has a transparent texture.

I've already found out how to do basic transparency, but when I try to

use a texture which has an other alpha value than 0 or 255, the alpha value for that pixel changes to 255.

Thanks for any help.

I had the same issue, see here:

for how to fix it.

Thanks for replying, but my issue still persists. This is my texture: , but the block looks like this:

What render layer is your block on?

Please also post your code, preferably as a GitHub repo.

@DavidM Here is my github repo:

https://github.com/Budschie/Deepnether-Mod/

I use the translucent render layer, but I also tried cutout and cutout mipped, but those didn't work either.

By the way, I have no idea how the render layers work, what performance impact they have etc.

I also noticed a weird behaviour of the block rendering, the pixels are flickering a bit.

Flickering normally means that you're trying to render two quads directly on top of each other (called 'z-fighting').  Remove one of the quads or move it slightly (say 0.001)

 

Is your block supposed to be translucent (like ice) or have holes (like glass block or leaves)?  The first one needs transparent layer, the second needs cutout layer.

@TheGreyGhost I'm sure it is not z-fighting, because there is no pattern that usually occurs when I have z-fighting. The whole brightness of the pixel changes.

It should be translucent like for example ice. But when I set the RenderLayer to translucent, the alpha is still either 0 or 255.

Howdy

I looked at your github repo but it doesn't compile.

@TheGreyGhost That's strange. It could be because I use AdoptOpenJDK as a compiler. I run my project with the minecraft jre. Make sure to use java 1.8. Maybe that will fix the problem.

@TheGreyGhost Oh, I forgot to update my BlockInit...

Aaand I forgot to add StructureIDPacket.java...

I finally managed to solve my issue: I just had to extend my ModLeavesBlock from BreakableBlock instead of LeavesBlock.

That fixed the transparency issue... But I'm not exactly sure why. Maybe some instanceof checking.

Ah, yeah you're right.  Vanilla does have a few of these dirty "quick fixes" hidden away in the guts of the code. 

 

   @Deprecated
   public static RenderType getChunkRenderType(BlockState blockStateIn) {
      Block block = blockStateIn.getBlock();
      if (block instanceof LeavesBlock) {
         return fancyGraphics ? RenderType.getCutoutMipped() : RenderType.getSolid();
      } else {
         RenderType rendertype = TYPES_BY_BLOCK.get(block);
         return rendertype != null ? rendertype : RenderType.getSolid();
      }
   }

and

   public static boolean canRenderInLayer(BlockState state, RenderType type) {
      Block block = state.getBlock();
      if (block instanceof LeavesBlock) {
         return fancyGraphics ? type == RenderType.getCutoutMipped() : type == RenderType.getSolid();
      } else {
         java.util.function.Predicate<RenderType> rendertype;
         synchronized (RenderTypeLookup.class) {
             rendertype = blockRenderChecks.get(block.delegate);
         }
         return rendertype != null ? rendertype.test(type) : type == RenderType.getSolid();
      }
   }
