Hi, I need to render a scene one time but with possibility to switch a different material to one object.
is there a way to assign two texture to one object, and switch one and other in post production, maybe with render elements?
No, sorry. You’d have to render twice - you’d could however use “render selected” second time around to speed up the second rendering (be sure to include any objects where the changed object is reflected or refracted in / through), then overlay in post.
(edit depending just how different the material is - if it’s a color change only, you could use ObjectID mask to mask out the object and use Photoshop and other tools to adjust hue, saturation, tint, etc).
Thanks. I have to render twice, becouse I run render night and I have no time to switch to render selected objects.
You can animate material and change it via material modifier
Corona implement Added CoronaSelect map and CoronaSelectMtl material with latest beta. One step closer my need. Maybe it will be added in latest version with render elements.
