I have 4gigs of ram in this machine.
I cant seem to load a 32k world map image, into lightwave.

Any ideas?

Mac or PC?
<plug mode on> http://www.infinimap.com <plug mode off> ;)

LW generally has problems with large image maps, even more so in the 32bit version. Even though you have 4GB in your box, your OS is likely to use a max of 3.5GB, and LW will use no more than 2GB.

I am rendering a scene of the earth that has 16k maps on it (4 maps)

1 color map at 16k

1 bump map at 16k

1 holdout map at 16k

1 cloud map at 16k

the total scene with polys takes 2.2GB actual ram and another 2GB virtual memory

I have 8GB ram on a G5 with OSX 10.4

I can't seem to go much bigger than that, because of the 32bit memory limitations of LW.

Would you care to share your 32k image map with me and I would love to give it a whirl?

Well, I've rendered a scene with the full Blue Marble (at 40.000x20.000 RGB) ... on a 512 MB machine ;)
Not with vanilla LW though... :p

Mike,

Have you considered porting Infinimap to the Mac? You can contact Richard Brak and he will port it for you for free. He has ported many LW plugs.

We could really use a mac version. (Stop bragging and making us mac guys drool :)

Cheers,

Yes, once I get the PC version of the commercial plugin out of the door.

I know and even though I have the most respect for him, I will not be giving out the source code to anyone, sorry. Also, there is a whole bunch of supporting code that will need to be ported as well...

LOL... :D

How on earth did you load up 4 seperate 16k maps into lightwave ?

- Use UVs on your globe and cut up the map.
- turn the Mipmap settings to low or off
- convert it into an 8bit palettized IFF on Photoshop (you might need to get the PS saver off the extras folder on the PS CD).

One of those should help...

Cheers,
Mike

infinimap seemed pretty cool. Further development will be interesting.
But in this case, I wasnt able to apply it to spherical geometry, IE a globe.

Coming... But you can even trick the current version by morhping your geometry ;)

Yes it is the Earth :) It took a lot of finessing. And I had the old tiff loader error (bad magic number) problems as well (8.3 Mac). So I emailed support about that.

It was just brute force. OSX 10.4 supports 64bit memory addressing so I now can access all 8GB ram. However LW crashes after about 2.5-3GB ram. So I was right on the edge of the envelope pushing the limites with LW memory management capabilities. Any more image maps and it would not load.

I would love to get my hands on something like Mike's plug though.
