Ghost is invisible

[regulus79]

When meeting the ghost at various places in the game, the entity has no texture or model.

When I rightclick it, it still gives the dialogue, but other than that it is not visible. I am guessing this may be a problem on my side, since Nathan.S's video review seemed to load the ghosts just fine.

Does it happen consistently for certain ghosts? Is it random or is repeatable? How often does it happen?

[regulus79]

It happens to every entity, even the crystal at the top of the castle (I didn't even know there was a crystal up there until I watched Nathan's video)

Can you post your minetest.conf file, especially anything related to graphics settings?

I managed to repro it by just disabling shaders. Looks like it's an engine bug ... one which I was pretty sure we had fixed a long time ago (like 5.6 or something) so I don't see why it should be back now...

I guess there should be a warning for now like "you should enable shaders, or the ghost will be too realistic (invisible)"

[Warr1024]

It looks like there is a bug with using opacity <= 127 when shaders are not enabled. If you make sure that the opacity is >= 128 then it should work correctly in both cases. Even if the bug is fixed for 5.9, until you are ready to drop support for 5.8 and earlier, you will probably need to do this at least as a workaround. Hopefully the increase in opacity is not enough to make the ghost look "too solid". If we need it to be more transparent, until the upstream bug is fixed, we would need to use some stippling/dithering style of transparency to make up the difference.

I think the higher opacity looks ok. Thanks for figuring it out!
