is it possible to layer bump maps? I have 1 i'd like to use to get general grain and noise, and another that I'd like to use that would have a graphic bump into the surface
You can't do this at the moment.
Combine the bump maps in Photoshop...
I hope to get this in KS4.1 ;)
It's handy for all sorts of things and merging bitmaps is an option, but after a while you've got a forest of bumpmaps all over the place.
Yeah, KS badly needs a material layering system - it's one of the things I love about Maxwell RenderW, really rich, complex shaders can be created...
We are trying to keep things simple. It is not a matter of whether it can be done technically, but how we can expose in the most simplistic way.
We will consider it for a later release of KeyShot.
I understand keeping things simple. But just for the bumpmap, I would like this option.
For a short time KS user, it keeps things simple yes, but in the long run, ... how it is now doesn't keep my texture-folders simple ;)
