1.0.29 Translucent actor + model = crash

[Enjay]

I know that translucency for models isn't supported (yet?) but it shouldn't crash the game right?

On setting up a model to replace an actor that I had forgotten was translucent, I got a crash.

Commenting out the translucancy properties for the actor allows the model to work without a crash.

I had the same problem with my 3d lost soul having the SoulTrans set, I've had to change everything to "Normal" and set alpha to 1.0. It'll probably be supported in the next release anyway though...

[Nash]

Confirmed. Crashes my nashgore.pk3 too, which uses translucent flat polygons to fake floor decals.

[Torr Samaho]

Can you give me a test wad? It definitely should not crash.

[Enjay]

Can you give me a test wad?

Here you go.

Load up the zip and type summon test01 and a small green bottle will appear at your feet.

Summon test02 and a translucent one should appear, but the game crashes instead.

I haven't checked what happens if an actor becomes translucent during play (eg using A_SetTranslucent in its DECORATE).

[Torr Samaho]

Works fine in Skulltag. I'm pretty sure that the crash was caused by a NULL pointer exception from the GZDoom 1.0.29 code, that I fixed after upgrading ST to this. When Graf backports my changes to GZDoom, the crash should be gone.

[Graf Zahl]

I did so already.

[Enjay]

Not only does it not crash, it's actually translucent! Good news al round.

[Nash]

I'd like to fix this myself so that I can continue working on my project. Is this easy to fix? Can you tell me how?
