Oolite Bulletins

yeah! I've been uploading things to box this morning and it looks like I overwrote the griffin with the ophidian
It should all be back to normal now, with an updated Wolf OXP as well (now at V1.4)

Seems to be a problem with the Griffin:

oops, sorry - i think this is a cut and paste error - the griffin only has the one decal but i copied a bit of code into its shader from a ship with two decals, i'll get the OXP updated, the manual fix is to open
griff_griffin1_NPC.fragment, go to line 241 and change it to from edit: actually there's references to a missing decal in the player fragment shader too - i've fixed those now, might be easier just to redownload the oxp from box (now at V1.2.1)

I've made a few small changes to the thargoid oxp, to add in a simple Iridescence effect I cribbed from an example shader by Diego Inácio
https://github.com/diegoinacio/shading/ ... nce_simple
and also spruced up the laser gun glow and 'sparking damage' effects a bit

I've now installed the full 1.79 set to my trunk install, and have a couple of questions..

1. Is the shipset compatibility OXZ needed, or has the trunk version of the shipset been upgraded so that this is not necessary?

2. Why, (extra detail shader setting, if that makes a difference) are they all so dark and colourless?

I'm running those core OXPs too (apart from the start-in-a-Griff-Cobra OXP), without the shipset compatibility OXZ (Griff's all-in-one shipset hasn't been upgraded yet, as far as I know). That's a very dark Cobra III, Diz - they look nowhere near as dark on my machine. They look fine, in fact.

Thanks for that, Cody..

Diz, has your computer got an Nvidia card and the new drivers from last month? they don't like a particular line in the fragment shader that deals with applying the ship decal, from your screenshot it looks like the shader for the gun subentity is working but the shader for the main part of the ship has failed because of this line in the 'decaliser' function, here's a post where we work out what the problem is:
https://bb.oolite.space/viewtopic.ph ... 02#p219002
you'll see some lines like this in the log if it is indeed this shader bug if you're OK for internet bandwidth it might be worth grabbing a few of the updated OXP's from here: http://www.box.com/shared/rpkms25cc9 (in the 'Core Shipset for Oolite v1.79(trunk)' folder) and seeing if they work OK, dump any bundle OXP's of these ships as they've gone really out of date.

I guess I should think about making OXZ's of these, i'll have a look through the guide that was posted up a while back - would there be any need for a bundle OXZ or should we get rid of that now - it's a hassle to keep updated as it's such a massive upload

Your choice, Griff - but I'm quite content with the individual OXPs as is.

Nope.. it's an old(ish) ATI/AMD X2300 Mobility Radeon chip. Drivers are the current standard Linux drivers for the chip.

Code: Select all

(0) : fatal error C9999: *** exception during compilation ***

I'll check that out.

No problem on the bandwidth front, but that's exactly where I downloaded them from, just 2 days ago.. I did see you've updated a couple since, and will grab them, but other than that, this is happening with the current versions.

Diz - how does the core shipset Cobra III appear on start-up on your machine? That is fine, I presume?

They're all fine.. but I'd rather Griff's shadered ones, if possible.

<scatches head> A strange one, Diz. With the start-in-a-Griff-Cobra OXP, my spinning Cobra looks like this.

I've updated the tharglet oxp (for Trunk and v1.77.1) to have the same iridescence effects that yesterdays thargoid shader update has.

Not sure why but the tharglets are not going hostile for me in Trunk 1.79.0.5796-140613-5dc7327
they're just hovering there but they are going inactive once the mothership is blown up - they seem to behave properly in v1.77.1

I'm a bit stumped with that shader error diz, anything in the log? you don't happen to have some sort of conflict going on with an old version of the oxp still being found somewhere on your system and loaded into oolite - even though I've been updating the oxp over the last month or so, the shaders in the new versions will have the same filenames as the old ones.
here's an earlier (pre NVidia driver workaround) of the oxp, have a go to see if this one works

Thanks.. will check it out.
