Moving in 3D space and Light transmission (trapcode shine)

[David Johnson]

Is the layer that the Shine effect is on a 3D layer and, therefore, able to be affected by camera movement?

[Michael Szalapski]

I wouldn’t put Shine on a 3d layer, I’d put a 3d null in there and use an expression to attach the source point to the percieved position of the null.

thisComp.layer("SHINE NULL").toComp([0,0,0]);
where SHINE NULL is the name of the 3d null you’ve created.

Well, what I said doesn’t necessarily apply, it depends on your situation. You may want to do what I suggested, you may want to make it a 3d layer and move through it…it all depends on what you’re doing in your comp.

Thanks for the replies, the shine layer is 3D, but still doesn’t react to camera movements.

What I want to acheive in the comp is to put some ground in, put people in there and be able to do camera moves around the people with the light reacting to the camera movements.

I’m trying to add that expression to the shine layer to the null, but i’m completely inexperienced with expressions, having only started to dabble. To what parameter would I assign that expression?

Thanks!

[Michael Szalapski]

That expression was in case your shine layer was 2d and it was to be applied to the Shine source point.
How are you creating your Shine? Is it an adjustment layer? I wouldn’t do one of those 3d, THAT’s when I would use the expression trick.

If your layer is 3d and not an adjustment layer, it should be reacting to the camera movements. Although, to be honest, that shouldn’t matter.

I’ve got Shine affecting a comp with a fractal with a track matte to simulate water surface, and shine shining through that.

Not sure if this will help, but I have the ‘collapse transformations / continually rasterise’ sun icon on in the comp, too otherwise the sun doesn’t show as shining through the water.

Thanks

[Brent Griffin]

Ok, it seems I answered my own question to an extent…

I turned off the ‘rasterize’ button and moved down the position of the ‘shine’ comp and now it seems to be reacting to the camera, but I now have the problem of having a light layer reacting in 2D in a 3D space…

So this at least shows me I need to research what the rasterise button ACTUALLY does, but maybe shine just doesn’t do what I was hoping, which is light a 3D scene in a 3D way.

Sorry to necro this thread, but I’ve noticed that with Shine (and other effects too) using an expression to have the source point follow another layer doesn’t give the expected result. The source point always seems to be offset from the layer it’s meant to track. Does anyone know why this is and how to correct it…?
