Operating system & version

What you did

Ran new pipelined 3d examples

What happened

Summary: most examples work as intended, but others are 'wrong' or strange (look like something is missing)

Screenshots

pbr_pipelined:

note: regular pbr example works just fine.

shadow_caster_receiver_pipelined:

in this one pressing C or R has no effect on what is being displayed on screen.

texture_pipelined:

transparency doesn't work.

The pbr_pipelined example will be fixed by #3182

[mockersf]

pbr_pipelined issue is a regression introduced by #3192, fixed in #3200

shadow_caster_receiver_pipelined is a known "issue", examples were not updated after decision to disable shadows by default in #3126, fixed in #3201

texture_pipelined is from #3072, fixed in #3202

Thanks for noting these! And for submitting fixes. I have been testing with more advanced scenes which make specific use of these features or demonstrate issues with them and I missed updating the examples that they affect.

after git pull I see beautiful shadows in 3d_scene_pipelined
but also not so beautiful artifacts in shadow_biases_pipelined

[superdump]

The artifacts in shadow_biases_pipelined are intentional. It’s a bit of a playground to let people get a feel for adjusting the depth and normal biases for shadow maps. The instructions printed to the terminal tell you how you can adjust them. This has confused other people too so we should make the example’s intent clearer.

[adsick]

yesterday it was looking fine (so I didn't report here) but today I tested again and was surprised))

[adsick]

shadows in shadow_biases_pipelined still look kinda odd tho, I tried adjustments but they don't seem to make it better

[superdump]

The default values that I found to work quite well are: depth bias 0.02, normal bias 0.6. Hopefully that helps you to see how adjusting the biases behaves.

[mockersf]

#3200 was merged which should fix example pbr_pipelined, and it should also impact shadow_biases_pipelined

how it renders with the default values for me:

and with the values from Superdump:

I confirm that pbr_pipelined works (for me)
