Hi

Dont know if this is a limit or a bug.
But i have 2 object on top of each other. intersecting.

In this example i have some interior fundamentals, that i want to fade away at the same time as the outside of the house fade inn.

The problem is when the interior fades to invisible...... it kinda cutsout the mesh of the visible one? Hard to explain, the pictures should get the point across.

I have tried the visibility slider in the object properties, and the opacity slider in the material.
Both yield the same result.


Cheers

Hi Stir,
your issue seems to depend on complanar surfaces. this creates artifacts as in your case.
Looking at the screenshots (triangles polygons on objects) I think you have some problem with rayepsilon setting and / or unit of measure.
Set unit system setup in meters, then display unit scales as you wish then adjust rayepsilon eventually.
To get around the issue about fading, you should have non-complanar surfaces, making a very small scale.

yes!
the rayepsilon setting!! i keep forgetting about that bastard! haha.

I solved the fading issue by scaling the house a little so its larger then the interior, probably something one should have dont in the firstplace.
I just found it strange that the Invisible mesh made a cutout on the visible mesh.

I might take a closer look at it when this project is done, until then this works!

Thanks paride.

best regards

It's funny I just noticed this issue a minutes ago and made a post about it. We shouldn't have to adjust ray epsilon settings - the visibility of 0.00 should take care of that but there's still shadow. Please fix.
