(UNSOLVED) 1.15.2 problems with translucent particle

[xX_deadbush_Xx]

Hey there,

I have a problem with a particle. Here is an image: https://imgur.com/a/pf2F9mh

As you can clearely there are issues when the particles are overlapping. Also it does not render when a translucent pixel is in front of it. I am using a custom particle Renderer (Yes, I have tried the vanilla translucen one).

Here is the renderer:

	      public void beginRender(BufferBuilder buf, TextureManager texmanager) {
	  			RenderSystem.enableBlend();
	  			RenderSystem.blendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE);
	  			RenderSystem.alphaFunc(GL11.GL_GEQUAL, 0.003921569F);
	  			RenderSystem.disableLighting();

	  			texmanager.bindTexture(AtlasTexture.LOCATION_PARTICLES_TEXTURE);
	  			buf.begin(7, DefaultVertexFormats.PARTICLE_POSITION_TEX_COLOR_LMAP);
	      } //there is also some resetting stuff in finishRender()

I have tried disabling the depthMask but then there is a different issue: The clouds are rendered in front of the particle (I can provide an image if necessary).

 

Does anyone have an idea on how to fix this?

Yeah, I had this problem too in PneumaticCraft, but (with much thanks to Botania, which does it right with the mana pool particles), I got it figured out:

 

You will need a custom particle render type, like this: https://github.com/TeamPneumatic/pnc-repressurized/blob/1.15/src/main/java/me/desht/pneumaticcraft/client/particle/AirParticle.java#L91

 

And return that from your getParticleType() method: https://github.com/TeamPneumatic/pnc-repressurized/blob/1.15/src/main/java/me/desht/pneumaticcraft/client/particle/AirParticle.java#L71

 

The important thing is the alternative GL blend function (GL11.GL_SRC_ALPHA, GL11.GL_ONE), and GL_GREATER rather GL_EQUAL in the alpha func.

 

Update: just realised you're already using GL_ONE in a custom render type.  Have you also provided the finishRender() method in your render type?
