What's the difference between Ambient modes?

I've normally been using tdm_ambient 2 as that's what came with SVN all those years ago. But I noticed the mod only shows 2 choices when using the console window, 0 and 1, with 0 being the suggested one and 1 being the cheap and fast one.

The only problem seems to be that 0 makes the textures in the map look....weird, like the ambient light isn't actually an ambient light but a point light. 1 looks normal and 2 looks the best but runs the worst.

 

2 doesn't seem to be documented that I can find, but still looks the best.

I always assumed I'd taste like boot leather.

The difference is as follows:

 

0 - uses the physical ambient light within the map

1 - turns the physical light off and uses the values of that light to illuminate the diffuse texture

2 - turns the physical light off and uses the values of that light to illuminate the diffuse, normal and specular textures

 

Now you mentioned that using the '0' setting looks like the light is wrong, this should only be true if you're using the default doom 3 interaction shader. Set your interaction shader to enhanced and the incorrect shading will be fixed with the '0' setting.

Okay I did what you suggested and my interaction shader was indeed set to Normal, or whatever the crappy version is. I set it to Enhanced and set the Ambient Method to Enhanced also.

 

Anyways I took some screenshots of each ambient method for comparison, can you please tell me which one it's supposed to look like?

tdm_ambient 2

For me, tdm_ambient 2 (Enhanced) is the best looking one.

 

EDIT: BTW here's what the console says about that cvar:

 

]tdm_ambient_method

"tdm_ambient_method" is:"2" default:"0"

Method used for ambient light rendering.

 

0 = Ambient Light method (uses the ambient light for the ambient brightness)

1 = Texture Brightness method (uses texture brightness instead of light. This i

s faster but looks worse)

 

So if I understand what you're trying to tell me, is that the description in the console is backwards?

I always assumed I'd taste like boot leather.

      Finally got my PC back from the shop after my SSD got corrupted a week ago and damaged my motherboard. Scary stuff, but thank goodness it happened right after two months of FM development instead of wiping all my work before I could release it. New SSD, repaired Motherboard and BIOS, and we're ready to start working on my second FM with some added version control in the cloud just to be safe!

      I've updated the articles for your FMs and your author category at the wiki. Your newer nickname (DeTeEff) now comes first, and the one in parentheses is your older nickname (Fieldmedic). Just to avoid confusing people who played your FMs years ago and remember your older nickname. I've added a wiki article for your latest FM, Who Watches the Watcher?, as part of my current updating efforts. Unless I overlooked something, you have five different FMs so far.

      I've finally managed to log in to The Dark Mod Wiki. I'm back in the saddle and before the holidays start in full, I'll be adding a few new FM articles and doing other updates. Written in Stone is already done.

      You cannot receive PMs. Could you please be so kind and check your mailbox if it is full (or maybe you switched off the function)?
