render to texture does not support lightmix

[kevinshane]

Hi, I think this is a bug for render to texture settings, it shows "interactive light mixing is currently not possilbe" when you hit the render button on the render to texture window

Hi,

I'm not sure I completly understand your issue.

Can you provide some more detailed reproduction steps? Information we ask for when reporting bugs can be found in my signiture.

Thanks,

Hi, thanks for the reply, it's very simple to recareate the "bug"(not sure if this is can call a bug...) but anyway, please hit 0 to open render texture window, then select an object in 3d viewport(anything, could be a teapot for example), then create a light and setup lightmix pass like as usual, then hit the render button on that "render to texutre" panel, you will see the vfb pop up saying all the lightmix lights are missing. that's all. seems like lightmix is not supported on render to texture? or maybe just a bug? because there is no reason when normal rendering support lightmix but when hit the render button on that panel will not support. thanks

Hi,

So I have looked into this.

Can you explain why you would need to use lightmix with RTT?

Currently when you use RTT it creates a new instance of the renderer which is seperate/different from the usual VFB. This is why you don't see the lightmix there. If you click the show VFB icon in the toolbar you will see that the usual VFB is loaded.

Thanks,
