Hi,
It would be GREAT if Corona would support Vector Maps in all Channels - at the moment it is only supported in the Diffuse Channel and it also works in the composite map as a layered diffuse map - but I haven't been able to use it on other channels. It is fx. not possible to use the very useful vector map as a mask in layered material, mix or blend - which could be very handy when you make decals or road lines or road signatures - well ton of things.
The good thing about vector maps is essentially that they are not loosing quality, as it is a vector map,
My main use would probably be in connection with a visualisation of streets - one vectormap can be used for road stripes and signatures in an entire city. No more uvw wrapping - wouldn't it be quite cool? As mentioned it works at the moment using a composite maps in the diffuse channel - but it could be much cooler if you could use it as a mask - on all channels.
Cheers
