Issue with a Projection Layer Lamp

[Jojon]

FWIW, I just tried adding a projection lamp and it worked just fine, with Blender PyPRP export and URU both on a WinXP machine with Gforce8800 (nv4_disp.dll v.6.14.011.6904) and DirectX 9.0c.

I can confirm that exported projection lights work, of course, but I can also confirm that dox's light does not work for me. At the moment I have no idea why.

Edit: at the moment, the problem may lie with the floor material the light is supposed to be casting on.

I'm going out on a limb here but, I guess it's safe to assume that the exported PRPs being fully created by PyPRP should be identical regardless of the OS they're created with, right?

right

A thought cropped up on another thread, are you using a laptop at all?

[Paradox]

No, this is a desktop PC.

What confuses me the most is that nobody can see the layer lamp, except for myself in Linux. I enabled advanced logging in the UruExplorer client and it tells me that everything loaded properly.

The lamp itself works fine, since I can see the shadow caused by it, and enabling it/disabling it affects the shadow. It's only the layer that isn't rendering on Windows machines.

I'm not taking the easy way out but I'm blaming this on a driver issue here.

[edit]
Under Windows having you noticed any missing layer lamps in other Ages? (Garrison folliage outside, Teledahn lamps shadows in upper shroom, Kadish folliage shadows on the ground etc)

[Nadnerb]

I disagree. There is something in this particular setup of lamp and surface that is causing it to not render as expected. I don't know what it is yet, but I know it's minor, because it is close enough to work under one implementation of DX, but not under another. I DO blame the driver differences for the change, but the original cause still lies in the files, since other projection lights work, and this one doesn't.

[Grogyan]

So it could be something relating to, say DirctX 10, instead when the rest of us use DirectX 9?

Truly weird

[Jojon]

I suppose it wouldn't show up on a shadeless material, if it's only the floor that is not affected, whereas the avatar and other objects are, but I seriously doubt something like that would slip under the noses of either Dox or Nad, much less both. :)

EDIT: ..and he DOES get a shadow. :7
