Water height in OAR

[Ilan Tochner]

Hi Alexina,

This isn't a standard service that we offer but we're willing to manually upload an OAR file with an offset for Discovery users who order a new Kitely Standard World, Advanced World or Mega World. We'll need you to buy at least $50 worth of KC, change your account payment method (in your Kitely account settings page) to "PayPal or Kitely Credits when available" then order the world using the New World button on the My Worlds page on our website (select a world size that matches the OAR file that you wish to upload and the empty land world template). Once that's done, send me an email with a link to the google drive where you hold the OAR file.

Please note that as this is a manual process we'll only do this for free once for every new Standard/Advanced/Mega world that you order. So make sure its a valid and working OAR file before you ask us to do this.

Thank you, Ilan. I was writing another message while you posted this. We need to be on Kitely. It is the only grid that meets the values of the Sendalonde Community Library.

Ilan, I am going to ask Balpien to make me another OAR. We don’t create our own OARs on DG. As soon as I have it, I will upload to Google Drive and send you the link.
Thank you for doing this.

Hi Snoots,

Keep it at 20m then the -80m offset from your original 100m water height will result in the water level you want.

LOL I actually figured that out AFTER I left the forum post. Never fails. duh.

If you load the oar with an offset of <0,0,-80> and then adjust the water height in the region/estate settings and rebake terrain you should be fine.

It's not always quite that easy. Offsetting the OAR will seriously mess up the ground texture and the way texture blending works on opensim, you can't simply offset the texture elevation ranges by the same amount and expect the same result. If the ground texture is important, you have to be prepared to do a lot of trial and error to get it right.

Also, I assume there is a reason why people want deeper waters. With a negative offset, there's a good chance some of the ground will end up with a negative height. With ubODE this means those parts of the region will not be accessible. With ODE or Bullet physics you can still go there but the light setting at elevations below zero will be very different (and absolutely wonderful for underwater scenes but that's another matter).

But with that being said, I don't understand how this problem occurs at all. Water level is a parameter that is supposed to be included in the OAR file so but shouldn't change if you transfer a region. I've only done it with OS 0.8 myself though, maybe something changed with OS 0.9?

Anyways, there are two better options than offsetting the OAR.
The simplest one is what Alexina mentioned in her original post: Correct the water level in-world after uploading (Alt+R - Terrain tab - Water Height).
The second is to do a double transfer. Export and import the OAR first, then go back and export and import as a RAW file. This method will certainly work and if water level is no longer supported by OAR files, it's also the only way to transfer water levels higher than 100 m.

Hey Alexina, I’ve run into something similar before when moving OARs between platforms. To get your world to match the 20m water height, you’ll need to lower the terrain a bit. I usually use the World Editor to adjust the heightmap or directly lower the land, but just keep in mind that you might need to tweak some of the builds to prevent them from floating or clipping.
