The VG Resource

HowTo (note, I will only cover what I did):
Premise: all files will be on a folder with the level's name on the "Spyro Edit" subfolder on ePSXe's root folder.
Generally, is good practice to leave each relevant file on the level's folder.

It's not that hard. You need to setup ePSXe to use SpyroEdit and Genesis.
* Boot up either game and Genesis.
* Once you load up a Spyro 2 or 3 level, you'll simply hit the "Save all" button on the "mods" tab on the SpyroEdit plugin.
* You may want to check the "separate bitmaps", save, and untick it and save it again.
* Then you can also (with the game paused, not frozen) go on the genesis tab and with hit "connect", then hit "send level".
* On genesis, simply export the level.
* On the Plugin, hit "Send All Objects" and wait until it's done, then also hit "Send Spyro" and wait until it's done.
* Export the level again, give it a different name.

!! If on spyro 3, or on a level on spyro 2 that has a different arena for the minigames, simply hit "new" on genesis, then load the area up, pause, and do the level loading process again (Send level, Export Clean, Send all Objects and Spyro, Export Full).

We're done with the level.dae files. Part 1 is done, now onto the skybox work.

Part 2: Skyboxes.
!! On VSE, the sample file will not save as either Cubemap PNG nor Panorama PNG, but will probably save as a OBJ. Spyro's sky.sky will !!

* Once you're done with saving all skyboxes files from each level, open up Vertex Skybox Editor.
* Click the Spyro with an arrow icon (Import Spyro Skybox) Button, and navigate where the exported skybox (Sky.sky) is.
* Hit "export", save it as a Cubemap PNG
* Open gimp
* Load the skybox
* Select an area that is equivalent of a single (1024x1024),
* Then under "image > guides" click "new guide from selection"
Do this until you've "separated" all faces
* Under image, hit "slice using guides"
* Save each FULL image with it's own name. It's a good practice to save them as a number from 1 to 6, under a subfolder called "Cubemap part" from the level of origin.
* Open up the website "cubemap to panorama".
* If done correctly, 1 and 6 are respectively Top and Bottom. while 2-5 are the sides. You will load them up in the following order: Up is 1, Bottom is 6, Back is 4, Left is 3, Front is 2, Right is 5.
On the Rotation options, rotate up by 270° and bottom by 90. the sides are ok at "zero".
Set the resolution to 4096 (1024*4) by either 2048 (wide) or 3072 (tall).

Save the file.
Rinse and repeat. Mental sanity is required for the duration of the process.
