| Hey !
I'm trying to create some level 7 to level 12 tiles for Earth, using celestia add-ons. But I have a bunch of problems :
♦ I was trying to blend the new tiles directly with the ones in the earth texture, but at level 6, there's styll a big distorsion between cylindrical and cubemap. So, I don't think it is possible for such a small level (maybe there's a software to do interpolation blending, starting with a bunch of points to match, but I didn't found)
♦ So I was thinking about creating a big texture with the wanted tiles inside, and use cubemap to create the maps. But there is a big problem : as I have level 12 tiles in cylindrical, it should be a very big image ! Impossible without a nasa computer...
Maybe it should be good to add in cubemap an option to process a bit of a cylindrical map as it is a very big map, and to create the corresponding tiles. Like I imput a 1024x512 image, saying it is part of a 32768x65536 map, between x=23040 and x=24064, and between y=5632 and y=3144 and I export this part in 512x512 tiles.
♦ After, it works well with grayscale and RGB images, but I never succeed to cubemapize a RGBA map : there is always an aliasing, or crashes. I use IrfanView to create these, and I think there's a problem in the way it create RGBA raw images. So it could be useful to have a png imput option in cubemap.
Want some music of mine ? Please go here !

| hi
i get many lines like this during processing:
Code Line 896 of 4128 in 32.0 seconds
Error reading line[6664].part[0] from input file
Error reading line[6665].part[0] from input file
Error reading line[6666].part[0] from input file
am i using the right parameters when converting my raw files with irfanview ? I used RGB order + interleaved
and still searching for a command line tool to do it
thx
------- OK --------
the answer is:
unless you know what you're doing, assume your Input16bit is false: whenever using photoshop, irfanview or xnview when saving RAW in RGB, it's always 8bit and not 16bit
then it's workingAdded (12.11.2014, 22:12)

hi
another subtle question 
i made over Rhea from http://photojournal.jpl.nasa.gov/catalog/PIA18438 which is 12015x6008 but it looks ugly with a long black line:
should i change the starting size of the raw ? which multiple should it be ?
thanks

| I opened the original cylindrical projection of that texture and at the left edge of it, there is a 4 pixels column lack of data (black) that seems to be your black line, you must zoom a lot to see it. One solution is to fill that gap for example with the next 4 pixels column adjacent area.

| For cylindrical maps, what would cause these artifacts?

| I'm not sure. If I had the location of the planet you exported them from, and the maps you exported, I could probably figure it out.

| Actually, the maps are entirely custom made, originally for Celestia. They are 4k png's. I added the grayscale specular map to the main color texture as a mask, and the clouds, which are 2k, are color + alpha, also png. The planet is my circumbinary that I mentioned earlier. The planet does have a bump map as well. I checked the se.log, but didn't find anything. All put together, in a zip or 7zip file, they are 29 megabytes. Would it be beneficial if I uploaded it somewhere?
EDIT: The textures were made with Gimp.

| The issue with the cloud map is being RGBA. It should be grayscale with no alpha. I'm pretty sure SE doesn't properly support RGBA cloud maps, though it would be great if it did.
I'm not entirely sure what issues there might be with the diffmap.
Also, could you post the catalog script you're using? I doubt there are any issues there, but still.

| Yep. That fixed it. I think part of the issue was that I was confused by the commented out advice comment made by the author of the planet tutorial in the code box:
Code //DiffMap "Icarus/Clouds" // Color texture
It said color texture, so I was confused and thought SE had cloud colors for Terra's enabled.
Thank you for the help!

Since I'm still having issues un-related to the clouds, mainly with the bump map, I'll post my scripts.

| You can't have a negative greenhouse effect. You also use a very small value for bump height, so I'm guessing the effect is not very noticeable. There's also no reason to use BumpOffset if you're not using a cube map, though I don't think it causes any problems.

| What I have noticed though, is that the planet has depth perception problems when I'm on the surface, but I don't know if it's my PC specs or a bug. Additionally, when I'm on the surface, the AGL indicator will say 10 meters, yet say I'm at 3 KM above the sea level -- even when I'm in the middle of the ocean. And my bumpmap itself does has clear distinction between high and low point:
(I shrunk the image to 1k jpeg for filesize, just in case)
Without the bumpmap, "ground level" sits me 20 km above the actual surface globally. And I set negative values for the greenhouse deliberately, to match the climate stats for this world I have posted elsewhere on the web for artistic license.

What I meant was that specifying a negative greenhouse effect has no effect on the stats of the planet in engine.

I'm guessing that it's not liking your cylindrical map. You might need to convert it to cubemap if you want altitudes to register correctly.

I don't understand what you mean.
