LSL commands/parameters for light projectors

[Tillie Ariantho]

Hello,


my feature request BUG-1497 (see below) got closed (not applicable). Why that? Do we have so submit working patches for features requests?

I think my request is pretty valid.



*LSL commands for light projectors*

Implementation of additional LSL command parameters:

I would add parameters for llSetLinkPrimitiveParams and llSetLinkPrimitiveParamsFast:

Flag: PRIM_CAST_LIGHT
Description: Let the prim with activated point light cast shadows.
Usage: [ PRIM_CAST_LIGHT, key projection_texture, integer fov, integer focus, integer ambiance ]

Texture, FOV, Focus and Ambiance are already properties of a prim, only they cannot get accessed via scripts yet.



Why can't we set those parameters via scripts?

(caveat... I didn't even see that issue, or have anything to do with
closing it, so this is personal speculation...)

Whether or not light sources cast shadows is an independent user choice
in the viewer, and we already have an option that allows projectors to
cast shadows.

Sure but I don't think that's what the JIRA was about. It's not about
forcing people to view shadows from light sources. It's about creators
being able to programmically modify the newer light parameters. (see
attached picture). Prim lights can be turned on and off, color changed,
intensity changed, radius changed, falloff changed, all from a script. So
why can't FOV, Focus, Ambiance, and the projected texture be changed too?
It really limits the usefulness for products.

Yep, that was the idea. It's no new feature lightwise, it's just scriptifying what's already there.

Not sure if you can see the jira history for BUG-1497, but it's been
linked (correctly) as a duplicate of a very old request, SCR-163.

Perhaps the feature is in limbo until it's decided to "protect" the
fragile rendering pipeline by neutering scripts in yet another way.
