Hmm New AMD Compressonator

I haven't had much time to play with this:

We have pretty much stuck to an old Doom 3 specific build but I am curious about how the latest versions might work

with TDM. The main question being whether the RXGB Normal compression quality has been improved.

Downloading...

No batch function, and it borked a normal I tried it on.

[nbohr1more]

Yeah, basically convert a super-details Normal map to RxGB DDS and see if it renders correctly (with minimal detail loss) in TDM.

Fingers crossed that the compression algorithm has improved since we last looked.

[Bikerdude]

No batch function though, so each file would have to be done by hand. What I want is a util that you can point at a folder and tell to to covert/compress every image file and sub folder and safe the converted file in the folder the original came from...?

It's open source now according to the website. Couldn't someone add a batch conversion option?

[nbohr1more]

I think you can do batch via command-line (Biker's enemy ).

 

After reviewing the source, I see that they've marked RXGB as deprecated "for import and decompression only".

So that's a bust for this purpose.

 

I can't blame them, AMD has a vested interest in moving away from RXGB to 3Dc\LATC

since their hardware is optimized for it (or at least industry standard DXT5n variants).

 

Oh well. I guess I'll take another crack at adding RGTC support to the image loader until Serpentine stops over to talk some sense here...
