Decal Texture Mirror Alternate tiles not working | Rhino 8 + Rhino 7

When you use “Mirror Alternate Tiles” in a Decal Texture things do not work as expected.
In Rhino 7 the texture does not mirror in both Rendered and Raytraced Modes.

  1. Here is the rendered view with 5×5 without mirror

  2. Here is rendered viewport with Mirror (no change)

  3. Here is raytraced with mirror

In Rhino 8 is worse. besides starting acting up while I was doing these tests and eventually just shuting down, here is what the same looks:

  1. here is rendered viewport without mirror and with the 5×5 tile. It changes the scale

  2. when you mirror it mirrors but in groups of 5×5, i.e. every 5 lines it does not mirror.

  3. In Raytraced the scale is not change but the texture is not mirrored.

Again Rhino 8 is slightly worse and slightly more unexpected than Rhino 7.

@wim
Any news here? were you able to replicate?

Hi Nuno -

I’m afraid someone that understands rendering in Rhino will have to take a look at this.
@nathanletwory, I see “Raytraced” is mentioned.

Decal alternate tiles should work in 8.9 in Raytraced.

Looks like it is broken in Rendered mode at least on Mac, and according report also on Windows (didn’t check)

Hi Nathan,
Can you post you test model?
Thanks, N

I had already closed this file right after I had posted the screenshot, but here is a new one:

Hi @nathanletwory
Here’s what I see when I open your file.

I just noticed there is a new build available.

After update the raytracing mirrors but the rendered view still looks off.

I am guessing this is one of those that will not be fixed on Rhino 7, right?
