As I can see, your "aqua" material is also invisible in material editor. Blend material doesn't like to work in all situations, we have to wait for Corona's dedicated version of such material.

Apart from the fact that support of blend materials in current Corona's implementation is really weak, your "aqua" material is very weirdly setup.

hi! The wood is clear to view the water interact, and the water opacity is forced to display the error

Here is my solution, despite the persistence of the error

Sorry to bump the thread with a semi-OT question, but is there a thread discussing the issues occuring when using Blend materials? As far as I've seen they work just fine here but I may have overlooked something?

Hi,

for the most part, they should work. But some features don't... you can not mix emitters (CoronaLightMTL), displacement doesn't work on blended material..., blended refractive materials sometimes produce odd results, and things like that...

But as long as everything works the way it should, you should not be concerned...  there's nothing bad happening under the hood... Of course... blended materials will never be as fast as base ones...  but that is to be expected with most renderers which are not build around layered shading system...

nice water ripples. the shape looks natural, but too bumpy imho. how do you do it btw Tiago4D. normal maps, or procedural wave?

Falloff maps can't be used for blending if you want to later change visibility object properties. Will produce strange results when selection no visible to camera for instance... Elements or polys using  one of the materials will be persistently visible untio getting rid if the falloff.

That's obviously a bug... so report it as a bug ;)

blend was completely reworked, now similar scenarios should work.

Old threads want some love too.
Just wanted to say, that CoronaLightmtl still doesn't work with the Blendmtl, which really pisses me off.
I have a lightsource on a model of tris that has a circle shaped light... since it's a strong light self illumination is not an option.

what if the light shader is the first material in blend, any difference?

First of all, I'm on 7.2, not the daily builds, but yes I tried multiple things and it still doesn't work.
If in first slot, the material isn't rendered at all
If in second slot, it renders the first mtl, but the area where coronalight is stays transparent.(isn't rendered).
It's not the fault of the mixing texture, that's allright.

well that explains it. I cannot magically make the feature appear in an older build ;)

Your signiture suggests otherwise.

Well, signing up for Dailies I suppose...
