Utility Combiner Material

[musashidan]

Hi, long-term Vray user who's been testing Corona for the last few days. Wow! It is fantastic and no doubt the future is bright.

I would like to see some kind of Utility material. MentalRay had one(before Adesk in it's wisdom decided to remove it for absolutely no reason)

Vray had the feature somewhat implemented recently with its VrayBumpMtl.

And there is also a Blur plugin material that I've been using. It's simply called Utility Material.
This blur plugin is the definitely the most feature packed of the three.

Congrats on creating such a brilliant renderer.:)

what exactly should this material do?

[musashidan]

It allows you to nest a shader/layered shader and gain an extra level of control over additional bump/displacement/etc maps independent of the maps within any of the shaders added to it.
It's really great for driving a bump with an identical mask map to give effects like chipped paint.

Here's an image I made a while back that might explain it a little better. This is using the free Blur Studios plugin 'Utility Material' (it's on the bottom left of the image)

I think whats really needed here is a corona blend material...

[musashidan]

Yes, a blend mat is definitely a must. And this utility combiner map goes hand-in-hand with a blend mat. It would actually make a nice feature built into a bland mat.
