Silvermistshadow, for the parameters that are labeled as "interchangeable", choose only one. No other obvious problems leap out at me, but you should remove as many of the notes as possible, just in case one is somehow confusing the script. Try specifying an orbital period as well.

I'll do that. The orbital period bit was weird, I thought I had specified one.

One more thing to wonder about while I'm fixing it: Color was discussed earlier, but the one that was discussed earlier only has three variables. Some of the color things I'm seeing here want four. Not sure what system it's using. Could be CYMK or anything else.

Here are some, at the end of the surface tag:

colorSea       (0.040, 0.100, 0.200, 1.000)   
     colorShelf     (0.150, 0.480, 0.460, 1.000)   
     colorBeach     (0.850, 0.740, 0.550, 0.000)   
     colorDesert    (0.770, 0.670, 0.470, 0.000)   
     colorLowland   (0.440, 0.290, 0.170, 0.000)   
     colorUpland    (0.640, 0.570, 0.470, 0.000)   
     colorRock      (0.220, 0.200, 0.200, 0.000)   
     colorSnow      (1.000, 1.000, 1.000, 0.016)   
     colorLowPlants (0.100, 0.160, 0.070, 0.000)   
     colorUpPlants  (0.090, 0.110, 0.040, 0.000)

So, the last number is 'alpha' then? Guess I hadn't noticed.

Planets still aren't showing up though. Got rid off all the comment lines I could find. Not a single one bothers to show up, and I checked the universe config and the file is in there.

"data/catalogs/planets/Comets936.sc"*/
  "data/catalogs/planets/asellus.sc"

Oh.. I recognise that */. That may be commenting out the next line. But then this isn't C so I can't be sure.

Included the star and the planets file as attachments.

Hi good morning, my nick is Exospace, I'm new to this forum.

Until today I created my planets in Celestia, but since the program is obsolete I decided to go to Space Engine is much more powerful.
I'm having some effort to adapt the operation of the program scripts, but I have practice with Celestia, I'm slowly learning to use them.

Anyway, I'm having a problem with the textures. For now I'm practicing with cylindrical textures like Celestia, I will not use cubemaps for now. I managed to put all the textures well, but when you insert an alpha channel in the surface map created me white sectors that do not appear if I remove the alpha. I'm trying to fix it myself but I find nothing wrong, the alpha channel is correct
Can you tell me if there is any solution for this bug (without cubic mapping)? Thank you very much in advance.

I show you the picture of my first planet.

Pardon my English.

Hello Exospace, and welcome to the forum. Please take a moment to read the forum rules.

That is a strange issue that you're having. I myself have also made custom planets with cylindrical textures with alpha channels that I originally made for Celestia, just as you have, and I never had any problems with it.

Could you please post your se.log file, your system specs, and the script for your planet? That might help in figuring out the issue.

Thanks!

P.S. Nice avatar smile

I did ask for the planet script, but I asked for the log and your system specs too.

I don't see any problems in your log either, and your graphics card looks fine. The only other thing I can ask is for you to upload your planet texture so that I can examine it and test it, to see if I have the same issue that you're having.

There is something wrong with your texture. When I removed the alpha channel, the RGB map looked like this:



You will need to edit your texture to fix this. SE is working normally.

How strange! When I created the texture was complete, no spaces. But that explains errors, now try to build again from the original map.
Thank you for your help, I could have been days without knowing what was wrong. smile

---------------------------------------------
I'm trying to to resolve the failure of the texture, but I think what makes Photoshop to save the PNG file with the layer mask, I turned off the option of interlocking and compressing, but still appears. I do not know how to make the PNG without the layer mask, normal alpha channels are not recognized.
I'm not used to put the specular map into the diffuse map, is the first time I do it and it's giving me trouble.
Sorry for all the work that I am giving you. sad

Photoshop

Photoshop does not save PNG with alpha channels properly. Save it as a TGA file. If you want to convert it to PNG after this for any reason then you can use SE to do this using the console command SavePNG data/textures/planets/arcadia.tga, if your texture is arcadia.tga and is located in data/textures/planets. In SE you can open the console with the [~]/[`] key (located above TAB on US keyboards). Alternately, you could just save/convert the file with another program, like GIMP.

Thank you so much, I decided to export the file in TGA format with alpha channel conventional and the result has been perfect. smile
