Particles with translucent meshes

[lima]

A mesh with opacity texture is always on the top of the particles

Hello, I have a problem with particle system and mesh with simple standard material and opacity texture. The particles are always on the bottom of the mesh. In my project this effect appears only when I change the diffuseTexture of this material, but on playground particles are always on the bottom. Do you know the solution for that? I tried many different solutions and nothing is good enough. E.g. hasAlpha parameter makes the edges not good enough, there are black pixels etc. Here is the pl…

Is there no better way than renderingGroupId? Here is my issue:

1. I have a swimming pool mesh
2. with translucent water texture on top
3. and bubble particle effects above the water
4. it’s in a room with walls.

The translucent water texture and the bubble particles both need to be same renderingGroupId as the pool so that I can’t see it through walls. But then the bubbles don’t appear if there is water behind them, relative to the camera

It would be easier to help with a PG, but it seems you forgot to use scene.setRenderingAutoClearDepthStencil(1, false) to avoid clearing the depth buffer between rendering groups 0 and 1. If you do this, you don’t need to use the same renderingGroupId as the pool, you can use 0 for the pool and 1 for the water/bubbles.
