Rendermask unclean edges

[Mokiki]

I'm currently having the problem that if I use the rendermask (selected option) I get unclean edges as a result for the selected objects. Even if my AA works fine for the rest of the scene.
In the example screenshots I rendered 3 boxes in all gray and than changed the bigger box to be red and reflective. I marked a few of the error spots. In the second screenshot I rendered the whole image again with the big box still having the changed material. Do I have to change some settings if I use the render mask feature?

*edit* the images appear a bit blurry because they are not displayed at 100%.

Hello,

Are you using the vray frame buffer or the max one ? And which image sampler ?

[Mokiki]

I'm using the vray frame buffer and the adaptive image sampler

Could you attach this sample scene here as I'm missing something and can't reproduce the problem here ?

[Mokiki]

No problem. Here is the testscene.

Thank you for the scene.

The problem is with the visualization of the light cache calc phase - it messes with the alpha blending and produces these unclean edges. As a workaround you could disable the visualization (show calc. phase) while we think of a better solution.

Thanks for checking the scene out and providing a workaround much appreciated

when will this issue be fixed?

Hello,

The specific issue here was due to the Light cache preview. The problem was fixed long ago - when there is a render mask the light cache preview is automatically disabled.

If you are having an issue with current builds - then most probably it is some different problem. It would be best if you could share a part of your scene or send it to our support.

Best regards,
Yavor

aha, the scene was already sent to chaosgroup ticket number 165270, it stil exists in the new builds using anyone of the rendermask options which is a bit of a pain in the ass really
