<mntmn> marex: me and probably dos1

<marex> mntmn: did you notice texture corruption in the exit light cone ?
<marex> mntmn: also, there are supposed to be these stars , they aren't rendered
<cphealy> marex: IIRC, this issue with neverball has existed since the "beginning" with etnaviv. Here's a youtube video from wumpus shoing neverball on GC3000: https://www.youtube.com/watch?v=QW5Jm78aYbI
<cphealy> Notice the stars are just rectangles.
<marex> cphealy: I know the issue exists, I also have an idea why
<cphealy> ahh, cool!
<marex> so it also exists across all the GPUs, great
<cphealy> IIRC, I saw it with both GC2000 and GC3000.
<marex> see above, it has to do with the VS not emitting the TEX varying output for PS to use

<dos1> exit cone looks much better for me on GC7000L than on that video
<dos1> but there are no stars indeed
<dos1> marex: ^^^
<marex> dos1: right
<marex> dos1: I think they are created using this glTexCoordPointer
cyrozap has joined #etnaviv
<mntmn> marex: how is the transparency done with the stars?
<marex> mntmn: I dont know, it seems to be encoded in some data files
<marex> mntmn: but I think this might be the problem indeed
<marex> the glTexCoord is bogus
<mntmn> marex: my question was going in the direction of GL_ALPHA_TEST
<mntmn> marex: ah, but i think that should work on pre-GC7000L maybe

<Chewi> I noted this about Neverball back in 2016 at https://github.com/Neverball/neverball/pull/134 but I forget the background
<Chewi> "With the particle code disabled, the stars change to squares but I guess this is expected."
<Surkow|laptop> was there anything wrong with the gles code in older iterations of neverball?
<Surkow|laptop> since we have a 2014 port for the gcw zero of neverball

<dos1> I'm not using Neverball's GLES support though, it's running on GL
<dos1> and I haven't disabled anything, it's using default graphics config
<Chewi> might be a Debian issue? https://github.com/Neverball/neverball/issues/170
