Setting shader constants per-scene node

[JTippetts]

Hi, sorry to trouble everyone again.

I'm trying to figure out the best way of setting shader constants on a per-scene-node basis, rather than just per material. I searched and found http://irrlicht.sourceforge.net/forum/v ... el#p251239 but that topic seemed to dribble off without the question being answered. Is there currently a way to specify shader constants/uniforms that should be set on a per-model basis? Or some other callback somewhere when a node is rendered that will let me specify shader constants?

Not possible, as far as I know.

The workarounds are one material per node, or drawing the needed nodes separately instead of by the scene manager.

It can be done using a Lighting Manager. The lighting manager performs routines on a per node basis, so if you need something executed prior to a rendering, you can do it using a Lighting Manager. Then, in the shader constants set callbacks, you can react to anything done in the lighting manager.

Yeah, it looks like I can make the LightManager work, with a little bit of work. I guess I just sort of automatically passed over the LightManager interface in my search, since what I'm trying to do isn't necessarily lighting-related. Thank you.
