Post subject:  Mac bug 16k textures

Hi all... just posting this to see if any mac users have noticed the same...

My new mac mini running Yosemite will not display my 16k textures... if I downsize to 8k they appear but it's a backward step.

I've only just noticed this as I normally use VTs

What is the value of Maximum Texture size reported by Help > OpenGL Info?
Which Mac mini model are you using?

This is typical of a video card driver not supporting the texture size.

I had this problem a very long time ago, but I can't tell on which system and which hardware.
However, I think I could reproduce this at work, on the very poorly supported 13" MacBook Pro with Yosemite (or the previous OS X)
I could even totally freeze that MacBook with Celestia on it. And it's the fault of the portable's configuration by our poor computer support at work.
This MacBook really sucks ! I don't think that the bug is on Celestia's side.

At home, I'm currently on an old Mac mini 2010, and an old 13" MacBookPro 2010, both with OS X Snow Leopard.
I'm using that special ultra powerfull Celestia from Da Woon (made with my help a few years ago).
That version never got published (what a shame !).
It is *ABSOLUTLY ROCK SOLID*. Not a single glitch !
That special version could not even be crashed by any means on my two home computers ! (and I did tried, if Da Woon remember) :mrgreen:
Really, I don't think I have any piece of software as stable as this version of Celestia (or maybe LaTeX).

Yes... Snow Leopard was able to display these textures with no problems.

My mini is a (Late 2014)
Graphics Intel Iris 1536 MB


PHL 234E5:
Resolution: 1920 x 1080 @ 60Hz (1080p)
Pixel Depth: 32-Bit Color (ARGB8888)

Tis a bummer... oh well.

16k textures are supported:

Max texture size: 16384

It's not clear to me why they aren't working for you (and I don't have a similar environment to reproduce unfortunately).
Do you see any strange output on your Celestia console (~ key)?

I get the same with a 16k jpg too...

here's the console (should be South America)...

I am a tad frustrated with this as I've spent some time converting the NASA monthly maps to dds (via Squish - thanks dirkpitt!)

8k doesn't cut it for me.

Back to the VTs.

If I remember well, it is the DDS textures that are causing problems to some recent Mac OS X drivers.
These textures were crashing the whole computer !

That's what I've experienced with the 13" Mac BookPro from my work place (**VERY BADLY** configured by the computer team !).

It looks more of a bug in MacOS...

here's finder with two textures... the 16k is displayed as a generic icon.
