Openrct2: "See-through rides" doesn't affect all rides

[ghost]

For example, carousels don't have any transparency, which defeats the point of the view option. I am pretty sure that any model (sprite?) that includes guests is not included.

Can you provide an image of what is wrong. Also I take it this is a OpenRCT2 issue and isn't in vanilla RCT2?

This is the ride when it is closed:

This is the ride when it is testing/open:

The behavior is from vanilla. I wouldn't call it a bug per se, I think CS did it intentionally. Maybe an original limitation? If I had to guess I would say that the see-through rides doesn't affect vehicles, and that the rotating part of the carousel is technically recognized as a vehicle.

"vehicles" on flat rides are drawn using VIEWPORT_INTERACTION_ITEM_SPRITE, whereas the other parts of the ride are drawn as VIEWPORT_INTERACTION_ITEM_RIDE. Only the latter type is made invisible

I believe its because its treated like a vehicle. So presumably we want to make vehicles see-through too when this option is enabled.

I'd say make flat ride vehicles invisible, and leave tracked ride vehicles as-is. I love being able to see a coaster train move with everything else disabled, in fact, I even use it sometimes to see where it's going when there's no other way to see the track.
