Anomalies in Celestia 1.5.0 for Win 32

[DonAVP]

OK, first I want to thank all those involved with the 1.5 effort, VERY GOOD.

I have found one thing so far. I had a add-on cloud map of Mars in 1.4 and a 3D model "mars-mons-valles-131.cmod". In 1.5, Olympus Mons sticks above the clouds. It might have in 1.4 (I never noticed it). I have edited the atmosphere height to 100 with no effect. What is the correct way to get the clouds above the 3D mesh? I have a normal and bump map but those are commented out.

One other item, I have Celestia running on a Mac and Win. The Sol texture is different on the Mac. I like the Mac look better than the PC. The PC looks the same as 1.4. Is this a known issue? I cycled (Ctrl V)through the OpenGL types with no change.

Thanks
Don

PS Not sure if this should have been in a new thread or is there an existing thread were these are address?

I think 1.5 is doing the right thing. Did you edit CloudHeight?

Yes, the default value was 30. I changed it to 100 but did not see any change. So I stopped. That was the reason for the post. Is this what is changed to make the clouds cover the top of the mountain?

I guess I can keep increasing the number but it did not see to be effecting the top of the mountain. Also I started noticing on the edge of the curve the planet a separation between the model and atmosphere not sure if this is related.

Can you post the SSC definition that you're using for Mars?

I have edited the atmosphere height to 100 with no effect.

I can get the clouds above Mt. Olympus by using atmosphere height to 30 and CloudHeight to 20. The CloudHeight can be a little lower but at 10, Mt. Olympus sticks out of the clouds.

This is the basic 1.5 solarsys file.

I think I figured it out. Silly me, I was editing the first record after the word Atmosphere instead of the cloudheight. I changed the value from 10 to 20 and it worked. It could be less, I have not checked. I am using another partial definition in the extras folder that came with the large Mars mesh. Below is that definition.

Modify "Mars" "Sol"
{
Mesh "mars-mons-valles-131.cmod"
Texture "mars.*"
Radius 3396 #small
Atmosphere {
Height 50
Lower [ 0.8 0.6 0.6 ]
Upper [ 0.7 0.3 0.3 ]
Sky [ 0.83 0.75 0.65 ]
Sunset [ 0.7 0.7 0.8 ]
# Slightly bluish sunset, as seen in true color pictures
# from Pathfinder
}


Albedo 0.150
}

A question, what does the height statement control so I will know in the furture?
