Error: OpenCl viewport render doesn't work

[johannes.wilde]

Hey there,
i can't figure out why my OpenCL viewport doesn't work, while final render works fine.
I tried it with 2.2beta2 and latest builds.
The console gives me this error output:

[PathOCLBaseRenderThread::0] Compiling kernels
[PathOCLBaseRenderThread::0] PathOCL kernel compilation error
ERROR clBuildProgram[CL_BUILD_PROGRAM_FAILURE]:
<kernel>88: error: too few arguments to function call, expected 11, have 10

Maybe someone can help me with this?

Cheers,

Johannes

I think it has been fixed, have you tried a daily build (viewtopic.php?f=9&t=736) ?

[johannes.wilde]

Wow!
That's a fast reply!
I already have installed the newest builds. It does not work in my case.
It hangs with the same message.

[B.Y.O.B.]

Is there more to the log? Usually it should contain a traceback with the line of code that's failing.

I should have fixed the problem. The fix will be included in the next build (available in a couple of hours).

RT OCL is broken here too.
But in my case Blender simply stops responding. Need to force close.

[marcatore]

The same here!
Blender sometimes hangs up and if I try to make a render I have this error.

This after downloading the latest BlendLuxCore from maintenance branch and latest luxcore openCl build

The same here!
Blender sometimes hangs up and if I try to make a render I have this error.

I should have fixed this problem too, it was introduced in the last patch and it was related to the usage of normal/bump mapping.
