About Vray Decal & Displacement

[hiroaki_mori]

Hello. I'm having trouble with Vray. Version V-Ray 6 for Maya, update 2.2
When using Vray Decal, shadows resembling the Vray Decal's bounding box appear on objects using Displacement. This occurs when using Vray Sun or HDRI with a strong light source, but it is less noticeable with flat HDRI images of cloudy skies. Is there a solution to this?

Hi, thanks for posting.
Do you have displacement in your material for the Decal?
Please test these options in the Decal:

It will be best if you could share your scene. Please do that here or through the support tickets.

Thank you for reply.
I tried it, but unfortunately, it didn't solve the issue. I have contacted support.

I checked alpha values of the textures, and the Decal settings, but I couldn't fix it.
Also, after checking with AOV, this result is only affects the lighting pass.
I will wait for a response from support.

Thank you.
