Vray 2.0 - Vray RT problems

[stevesideas]

Hi there,

Ive just installed the latest beta of vray 2.0 and have some problems when using VrayRT GPU. As the image renders, blue blocks appear over the screen and change in colour. Also the colours are strange for the entire image. It works fine in CPU mode.

I have a gtx480 graphics card.

It was working fine in 3dsmax 2010 when using just vray1.5 sp5 and vrayRT GPU.

Any ideas ?

Does this happen on any scene? Can you show an image of how it looks. There aren't any major changes between the two versions.

Best regards,

Actually I can reproduce the issue here; will be fixed in Beta 3 - thanks for the pointer!

Best regards,

Ive attached an image to show you what is happening today. I just have a blank yellow screen now when using GPU. CPU is rendering fine still. This is occuring when using max 2011.

This is max 2011 - just a yellow screen


This is max 2010, the same problem I was getting on max 2011 last night.


As I said, when I had vray 1.5 sp5 and the latest beta of VrayRT GPU, it worked fine.

Yep, thanks for the images! Will be fixed for Beta 3.

Best regards,

Sorry, I got your message after I posted them When is beta 3 going to be available ?

[vlado]

It is available already from our site.

Best regards,

Great. Thanks a lot.

Vlado. Im still having problems with this. I have updated to the latest Vray2.0 build which I assume updates RT as well. I still have different coloured buckets. Im using an entirely different scene.

[vlado]

Does it still involve the car paint material?

Best regards,
Vlado

[stevesideas]

No, a completely different scene with no car paint material used.

This is part of the RT window.

[vlado]

Ok; which engine is this? GPU, CPU? One machine or many machines with DR?

Best regards,
Vlado

[stevesideas]

This is the GPU openCL engine. I have 2 480 GTX cards that are not in SLI mode. No other machines are being used. DR not used.

[vlado]

Do you get any errors in V-Ray render server window? What is the memory usage on your GPUs?

Best regards,
Vlado

[stevesideas]

Just checked the server window.

Memory usage: 111.94mb

Error CL_MEM_OBJECT_ALLOCATION_FAILURE (-4) at line 1716, in file ./src/ocl_tracedevice.cpp !!!

Thats the only error.
