Transparency issues in Sonic Rush

emeraldroguefan commented 1 month ago

All of Blaze's fire effects in Sonic Rush lack the proper transparency. I tried toggling every setting I could find to see if it was fixable, it does not look like there is anything on the user's end that can be done

If specs are needed:

Windows 11 7950X3D RTX 4080 64GB

Does the software renderer have the same issue?

This also happened in Sonic Rush Adventure.

The software renderer does not have this issue, no. Only OpenGL on melonDS. Works properly upscaled on other tested emulators though (DraStic, DeSmuME)

It shows up for me. Even on Open GL. Screenshot 2024-08-05 172342

This would just be another "the OpenGL renderer is woefully inaccurate" issue, in the latest dev builds, does it also occur for the new OpenGL Compute renderer?

Where do I find the dev builds?

The problem is way worse now lol

Not only is the transparency issue still there, all of the models are flickering like crazy.

Sonic has seen better days

It's not captured well in this screenshot, but there are small holes appearing all over his body as he moves allowing you to see the background

I swear I feel like I must have done something wrong

Edit: There was a major issue that was fixed at least. The black lines that appear on the overworld in HGSS do not appear anymore with the upscaler turned on.

This is mixing up probably a bunch of different configurations and issues.

The transparency issue is probably related to OpenGL compositing which is shared between classic and compute shader OpenGL renderer.

what do you mean by that?

The garbled rendering is another (known) issue with the compute shader renderer. Try changing the render resolution to workaround it.

they should add vulkan support now

please i swear to god

Sonic's model has a bunch of holes in it that were not visible on the old openGL renderer, regardless of render resolution

Lowering the resolution works, but I don't think that I would consider that practical fix. Never have I ever had to lower the resolution for a game in any emulator, this is usually a set it and forget it option.

Like, does it work? Yes, but at that point I wouldn't really feel comfortable recommending the emulator to anyone in its current state.

Are they also there at 1x (and not there with the software renderer)? If yes it is a bug which can probably be fixed. Otherwise I'm not chasing those polygon alignment issues, because you just can't win. DS games were never meant to be rendered at a different resolution than 256x192. More often the approach of the compute shader renderer of replicating the software renderer only at a higher resolution works, but well not always.

That is a exactly what workaround means. What you downloaded is a development version, so things not completely working are to be expected.

I can't tell if they are or aren't there with the software renderer, but it doesn't look like it? I don't know if this gives you any insight either, but it didn't happen with the old openGL renderer either
