If you need help you'd have to give a bit more information

D

Deleted UserOP•8/14/21, 6:46 AM

@Deleted User okay well I've had a chance to renderdoc it

D

Deleted UserOP•8/14/21, 6:46 AM

So

D

Deleted UserOP•8/14/21, 6:46 AM

Depth testing works if, get this, RenderDoc is attached.

D

Deleted UserOP•8/14/21, 6:46 AM

...I don't... I don't know how that works.

D

Deleted UserOP•8/14/21, 7:09 AM

Yay, this is how things should look

D

Deleted UserOP•8/14/21, 7:09 AM

D

Deleted UserOP•8/14/21, 7:09 AM

but renderdoc's attached

D

Deleted UserOP•8/14/21, 7:10 AM

with renderdoc not attached:

D

Deleted UserOP•8/14/21, 7:10 AM

D

Deleted UserOP•8/14/21, 7:10 AM

No depth testing.

D

Deleted UserOP•8/14/21, 7:33 AM

So yeah everything works fine now in terms of everything being batched correctly and alpha blending etc

D

Deleted UserOP•8/14/21, 7:33 AM

It's just that something about renderdoc and the way it works causes my engine to actually get depth testing

D

Deleted UserOP•8/14/21, 7:34 AM

and, without renderdoc, despite me enabling depth testing and setting a depth function AND adding a depth attachment to my framebuffer... Without renderdoc being attached to the engine, depth testing flat-out does not work.

Deleted UserOP•8/14/21, 7:48 AM

Do you Render to your own image or to one provided by windowing?

D

Deleted UserOP•8/14/21, 7:48 AM

My guess would be the depth buffer bits in your own configuration are low

D

Deleted UserOP•8/14/21, 8:09 AM

I render to my own image

D

Deleted UserOP•8/14/21, 8:10 AM

Depth buffer bits in my SDL2 config are 24, depth buffer bits in my own framebuffer are 24

D

Deleted UserOP•8/14/21, 8:10 AM

Depth function is LEQUAL

D

Deleted UserOP•8/14/21, 8:10 AM

Depth testing works fine when the app is run using renderdoc

D

Deleted UserOP•8/14/21, 8:11 AM

Depth testing does not work when I just run the app normally or from rider

D

Deleted UserOP•8/14/21, 8:14 AM

hang on a sec

D

Deleted UserOP•8/14/21, 8:14 AM

I just noticed this in the thundershock log

hard to tell exactly where that error comes from, I wish there were preprocessor macros in C#

D

Deleted UserOP•8/14/21, 8:16 AM

so I could wrap all the GL calls in a macro that, in release builds, just does the call, but in debug builds, does the call and checks/asserts errors

D

Deleted UserOP•8/14/21, 8:26 AM

Extension method with

[Conditional("DEBUG")]

[Conditional("DEBUG")]

[Conditional("DEBUG")]

[Conditional("DEBUG")]

V

vdvman1•8/14/21, 8:26 AM

Debug.Assert

Debug.Assert

Debug.Assert

Debug.Assert only does the check in debug as well

D

Deleted UserOP•8/14/21, 8:27 AM

Yeah, if you just want to check a single condition Debug.Assert is the way to go

D

Deleted UserOP•8/14/21, 8:27 AM

For more complicated stuff a method with that attribute will just be deleted when in release.

D

Deleted UserOP•8/14/21, 8:28 AM

(I still want to bring this to Silk.NET, but it's difficult to do without sacrificing perf)

D

Deleted UserOP•8/14/21, 8:32 AM

OKAY, got it working!!!

D

Deleted UserOP•8/14/21, 8:32 AM

you know what it was?

D

Deleted UserOP•8/14/21, 8:32 AM

Can't use NamedRenderbufferStorage

D

Deleted UserOP•8/14/21, 8:32 AM

Had to bind the renderbuffer, use RenderbufferStorage, then unbind

D

Deleted UserOP•8/14/21, 8:33 AM

D

Deleted UserOP•8/14/21, 8:33 AM

now it all works

D

Deleted UserOP•8/14/21, 8:33 AM

which means now I can start putting things back in place that I removed

you're getting me all exited to do another engine...

TechPizza•8/14/21, 10:27 AM

are you using glGetLastError or a debug context?

Q

queenvicky•8/14/21, 10:30 AM

glGetError

glGetError

glGetError

glGetError I think it is

D

Deleted UserOP•8/14/21, 10:51 AM

debug context in debug builds

D

Deleted UserOP•8/14/21, 10:53 AM

annnnnnyway now it seems the only thing that terribly smashes my FPS is... Circles!

D

Deleted UserOP•8/14/21, 10:54 AM

Circle rendering is.... complicated.

D

Deleted UserOP•8/14/21, 10:54 AM

Circle rendering is like the easiest thing to do what

D

Deleted UserOP•8/14/21, 10:55 AM

Wtf are you doing that you are having a hard time

D

Deleted UserOP•8/14/21, 10:55 AM

?

okay, let me rephrase
