Thanks,

It's getting there but it's still a little flat looking in spots. Unfortunatly I can't show all. One thing I'm finding out is there is a vast difference in a cloud texture with a cloud normalmap. The cloud normalmap will magnify the flaws in the cloud texture so it has to be near perfect. Little holes and missing data from the cloudmap show up like a sore thumb.

Starting today, I will begin a new journey that will leave me with limited computer access. My main computer where my work is done will be put into storage and all my work will stop. I will keep an eye on the forumn to see what's going on. Hopefully I can get up and running again soon. Although my normalmaps of clouds look pretty good from an angle they still have problems when veiwed from overhead looking straight down. Hopefully Don Edwards can come up with something better.

The other day while I was checking out a test I did on my 32k cloud normalmap I noticed a little dot moving across Lake Michigan. I clicked on it and it was the ISS. I hit the g key but nothing was there. So I installed the ISS model from the motherlode and afterwards I took this screenshot.

cartrite,

You might not get this in time, but I wil give it a try. Those little holes in the cloudmaps from BlueMarble are caused from very high contrast white. What ever was used to edit the image data simply took these over bright spots and removed them, leaving us allot of tiny holes in the tops of allot of the clouds. One way to fix this is to load the original into your image editing software and filll in all those holes by hand by either a tiny dot of white, or my prefered idea is to use the smug tool and to gently fill the void with neighboring cloud color. Not an easy task at the 16k or 32k level. But once its done its done and it becomes your super master to build all other from. I was thinking of doing this with my 16k and still might. At least to some degree.

Hey Don,

I think in one of the many PM's between us that I mentioned I was working on touching up the old cloudmap and got as far as 1/2 thru A1. A lot of work. Every time I thought I'd finnished a section, there would be another hundred or so holes.

After I can get up and running, I'm looking forward to working with real data and make a new cloudmap. I think that somewhere in that vast data access area from nasa, there must be some data that has cloud height data. As I mentioned I am going to try to write a program that will save this data as a signed integer 16bit heightmap after it has been processed "cleaned up" with ISIS. I think that this way, a more "true" normalmap can be created.

bh,
As far a the ISS looking incomplete, I don't know? I thought it didn't look right. I probally did something wrong or downloaded the wrong files. Anyhow I haven't got the time right now to play with it now. Mabey someday soon.

A sure sign of addiction??? :wink:
I really shoud be doing something else right now but.
A screenshot of bh's iss model.

The other screenshot of the iss was Orion_Nebulae's stage 13 iss with texture pack. As far as I can tell, after converting the model to cmod ascii, I noticed that all texture names were using upper case in the model's material definitions and all the file names in the medres folder were in lower case. I think this may have worked in Windows but the screenshot was taken with the Linux kde version. And I think Linux treats upper case names and lower case names as different. So the textures were not loaded.
