[1.3.17 r649]Dynamic Lights and Brightmaps

[Big-Boss]

No matter what I try I cannot get brightmaps and dynamic lights to play nicely together. I end up just getting a garbled mess (see attached image). The only way I've been able to solve it is to either turn off brightmaps or turn of dynamic lights.

Unless you post your hardware specs I'll have to close this.

Why can't people read the bug reporting guidelines just once and then follow them?

ATI Radeon Xpress 1150 w/ 256mb. I have absolutely no trouble with things like Doom³ and Q4.

I have absolutely no trouble with things like Doom³ and Q4.

That doesn't mean anything. These are completely different engines.

I also can't really see what precisely goes wrong in these screenshots. What precisely is the problem. It looks a bit odd but I can't really see what's going on.

Well I tried for hours using different settings in both setPNG and in the PNG itself when I saved it. So more or less what I see is the brightmap image being overlayed on the normal texture and what you see in the screenshot happens. But when I turn off dynamic lights, that problem completely disappears, and the same when I turn off brightmaps and leave dynamic lights on. When I turn at certain angles I can see the brightmap image completely overlay the texture without the grey garble and it is just the greyscale brightmap image. Dynamic lights simply refuse to work with brightmaps and visa versa, one has to be off for the other to work and things to display properly.

Here is an example of it on a larger texture. There is a dynamic light in that general area for testing purposes. The texture is supposed to be a wooden door with a purple pentagram that uses a brightmap to make the pentagram shine (yes I know the texture is out of place, I just needed a large texture to illustrate the problem). Turning at curtain angles will reveal a purple pentagram on a completely black background or with the grey streaks etc.

Hm.

To investigate this please post the map including the necessary resources and your GZDoom.ini.

Well, it works fine for me so it looks like a compatibility issue with your graphics card.

I began to figure as much. It sucks though because ATI has some recent driver updates that would probably fix the issue, but Dell has made it impossible to upate any drivers that haven't been specially branded by them. Dell's last driver update for my card was in 2007. I can only shake my head in disgust at this point. My next laptop will /not/ be a Dell.

I had the same issue with MSI and Nvidia, so it's not just Dell. I finally decided to try http://www.laptopvideo2go.com/ some times ago and it worked okay. But they're Nvidia only; for your ATI it seems the only solution available is http://www.omegadrivers.net/ati.php ...

This is one of the many reasons that I either build my own machines from components that I buy myself or buy from somewhere that builds machines from components that I specify. Of course, it's harder to do that with laptops but I have only ever bought one of them and that was for a present for someone else.

If I have my way (and the funds) I will be getting a custom laptop from AVA Machines that will best even the most insane desktop for about $3K.

And I will give that site a try to see what happens. Worst that could happen is I have to boot up on the XP software driver and reinstall the driver the laptop came with.


EDIT:
Gave the Omega drivers a shot, it works great. Everything displays just fine now . Tusen takk Gez. It was indeed my crusty-ass drivers (from 2006 if you're wondering).
