System.InvalidOperationException at ORTS.CABTextureManager.DisassembleFrames[T] (Cab texture causing exception with Bernina Bahn rolling stock)

[disc]

I'm getting the following error with a bernina bahn rolling stock, and it seems it's caused by the cab textures.

The consist which i used for testing, and causes error is: RhB 417 Bernina Express.con

I got also this bug. It seems that the Dxt1 textures on CAB of RhB_Gem type engin is implied.
Some more informations in the Elvas Tower forum.

Yes as i see the problem is that these have non power of two sized cab textures. I see texture with 703x 711 resolution, 1024*768, etc.
That is very rare if a game engine don't have problems with such texture resolutions.

I could not re-produce this bug using 417 consists. Seems to be fixed by the newer version?

[disc (disc86543)]

i couldn't find that consists, but if a Gem loco is driven, that still causing this error.

452 Tirano-St. Moritz default activty is using this, and causes error.
I don't know about recent update i downloaded the trainset 1-2 weeks ago.

[Jijun Tang (jtang-h)]

I think it is fixed. Could you please check with the latest code?

[disc (disc86543)]

I get the same error in current v1565

[Jijun Tang (jtang-h)]

Strange, I used the 452 activity and did not encounter any problem. I think the texture file may be damaged.

[disc (disc86543)]

I've reinstalled the full rolling stock, with updates, still the same error... Couldn't be the drivers or the GPU? non power of two textures aren't widely supported... actually it shouldn't work at all.

[Jijun Tang (jtang-h)]

This may be the case. I will try to use another computer (with lame GPU) to check it.

[disc (disc86543)]

I've looked at GPU info, and for opengl the "non-power of two texture support" extension is supported by my gpu, so it is probably with directx too. So not the gpu is the problem.

Fixed the crash in V1598.
