Normal map render with OpenCL

[Dmi3ryd]

Hi there.

I am having trouble rendering normal map.
If I select CPU as Device, the card renders normally and is similar to the one in the viewport.
If I switch Device to OpenCL it is practically invisible. What could be the problem and how to solve it?

Unfortunately, I can’t provide the image, because this is a personal project.

Thanks.

2.3

2.3

Try with v2.4, the problem is likely to have already been fixed.

Could you please help me with links?
Where can I find latest dev build?

Version 2.4 did not solve my problem!

I found the source of this problem.
If you use the material (with normal map) directly, when you turn on OpenCL, everything works correctly.
If you mix one material (with normal map) with greyscale image mask, then in this case something happens to the normals.
It feels like they are getting blurry.

Everything is displayed correctly in the viewport, but when rendering through OpenCL, a problem is visible.
With CPU no problem.

Tested on version 2.4 updated yesterday.

Can you post a test scene showing the problem ?

Yes sure.

Here is the video in which I show the problem:
