[Solved]Gas steam white texture

[spidernetlabs]

Good evening guys,
I bought on Steam the Collector Pack of Penumbra, I finished Overture, so I want to play Black Plague, but in the ventilation shaft the gas leak does not show properly. Some images: http://i.imgur.com/r1Zt8TN.png http://i.imgur.com/IjdXsuR.png
I have a mid 2010 iMac, these are the specs:
Intel Core i3 @ 3.06 Ghz, ATI HD 4670, 8Gb RAM.
I tried to lower all the graphics option, I also tried to re-install the game (done 3 times), but the problem is still there.
I don't get it, Overture works flawlessly, Amnesia too.
I hope you can help me to solve this problem!

Any news?

Can you attach your hpl.log from a run where you see the steam? (located in ~/Library/Preferences/Frictional Games/Penumbra/Overture )

My first guess is the fact that penumbra OS X is using an older Nvidia CG library (2.2). But seeing the hpl.log output will help narrow down what is causing the issue. Amnesia we dropped CG in favor of GLSL.

I have an ATI card though.

NVIDIA's Cg library is basically a high-level shading language that can work on any card.. GLSL is just the native shading language in OpenGL. (it wasn't really mature and available everywhere when Penumbra was being made).

Ah, I get it.
Well in the .log file I read a lot of errors and warnings (I don't know if it's common), but there's one warning that catch my attention:

Code: (Select All)

WARNING: Didn't find particle system 'steam01'

but I still don't know the reason of this

Can you attach a save game for that area? (also in that Library folder)

[spidernetlabs]

Yep. Just enter the shaft, and avoid the cracked floor.
