4.4.2 Torch-Light Shader issue

Postby ZDL_800 » Thu Jun 25, 2020 2:55 am

Hello GZDoom devs and hope you are good.

For example, download the GZDoom 4.1.1 and load up Diablo3D, now look at the torches, specifically the light shader, its perfect, 0 Zfighting bugs, the light flickers perfect.

Now load up 4.4.2 with Diablo3D, the torches light look like strobe lights, also theres zfighting bugs on the walls with overlapping torch light sources.

The dev stated its a bug with the newer GZDoom.

It looks a complete mess.

Please look into this as I cannot figure this out?

Thanks again.

I have tried many theories, reduced dynamic light radius, altering intensity, it makes no difference, unless the dev is wrong, and I have made some mistake here, I cant figure this out, and it worked perfect with like I said 4.1.1.

Can one of the GZDoom devs look into this please, theres zfighting bugs with the light shader.

Any reply would be great right now as its unplayable, looks like a strobe light.

Hello and thankyou for the reply.

Looks like you need all the diablo pk3 files for the game to start, but upon starting a singleplayer game, the torches are in view.

Here is the Diablo3D Link.

Here is the Diablo3D Patch.

I packed up GZDoom 4.1.1 and GZDoom 4.4.2 BETA, Here is the link.

https://uploadcenter.com/mr0bbpij41ao.html

Basically start a singleplayer game with any character, turn right 90 degree, and you can see the torches on the walls of the buildings.

Even as far back as 4.2.x the torches lightshader is the same I'm afraid.

On version 4.1.1 the light shader works correctly. You can see its more of a glowing effect with no zfighting bugs on the walls.

Thankyou for your time and hope to speak soon.

No one has time nor interest to test big mods with big downloads and convoluted steps to reproduce a problem...

Thanks for the replies.

I'm trying my best to delete as many pk3 files, Everytime I attempt to bypass the scripts, my edits break the game?

Really sorry about this, let me talk with the dev and see if any demo can be constructed as I fail many times.

I understand that you don't have the time, but it is one of the best GZDoom mods out there.

Thanks again for your time and hopefully get a demo ready ASAP.
