want to up a ship to a raven

I made a custom ship and I'm trying to get it to be upgradable to a Polaris Raven (shďp 411). I set the ship to be upgradable to that type, then I set a price. When I try to upgrade it, it says, "This ship type is not upgradable." What's wrong?

I'm new to developing for nova, so I could be off, but I would think that you would have to upgrade within the same ship type because variants use the same base sprites, etc. If that is the case you could make a Raven Junior which would look and act like a raven, but maybe has no weapons and crummy shields; basically a shuttle craft that looks and acts like a raven.

It isn't working. I copied the Raven resource from the files, modified the stats, created a düde, set them to appear in SPC-089, set them to be able to upgraded to shďp 411 at a cost of 100 credits. I capture 6 of them. None can be upgraded. What is wrong with my plugin?

How exactly do you "set them to be able to upgraded to shďp 411 at a cost of 100 credits" and what do you mean by "None can be upgraded"? Detail everything, details are important.

What ship are you trying to upgrade? Also, a pilotlog could be helpful.

First off, I am using a custom ship created in Mission Computer. Under the shďp resource field, I have set the UpgradeTo field to 411 (which is the shďp ID for a fully upgraded Raven escort). I set the EscUpgrdCost field to 100 (100 credits). For some reason, this ship cannot be upgraded in the game, even though the conditions for upgrading are set (because these two fields are set up). Does anyone here have a grasp of what I am doing? Help me if you are familiar with Mission Computer.

It sounds like you are doing everything right, did you make sure you are capturing the right ship?

Otherwise you can just change the upgrade of a common ship (shuttle for instance) to the raven.
