Hello,
First of all, the following example is a simplified version of a real project. The opacity map will be more complex and controlled by other geometry through a VRayDistanceTex.
I have a setup where I’ve cut an object in half by applying a clipping map to two copies of the same object. Please have a look at the images.
Image 1:
Top: Here’s the setup with two boxes, both cut in half with an opacity map.
Bottom: The problem. When the objects are moved together the transparent surfaces on one object interfere with the opaque surfaces of the other, and vice versa. I realise this is due to overlapping geometry.
However, please have a look at image 2, showing the same setup in Arnold.
Image 2:
The same setup but rendered with Arnold. This is to show that other renderers deal with this differently. I understand there would be a problem with opaque and semi-transparent surfaces interfering with each other, but with full transparency using a opacity map, I would expect it to work like it does with Arnold.
I would like to do this with VRay though, because Arnold is lacking a lot of nice features that VRay has. And I like VRay.
Is there someway to make a object's material invisible like in the Arnold example?
