3.30.02 beta + Max 2016 SP1: RT stuck when using activeshade as extended viewport

[LudvikKoutny]

Hi,

I just installed 3.30.02 beta to check out how RT with ActiveShade performs, as I had some trouble in beta 1 (update rate of viewport navigation was quite slow and often getting stuck). Beta 2 seems to be a bit faster when ActiveShade is launched as floating VFB, but unfortunately whenever I try to launch ActiveShade as extended viewport, it remains stuck on "Waiting for image data..."

[vlado]

Bleh, completely forgot about the extended viewport. CPU or GPU? If you look at the vraylog.txt file, what does it say?

Best regards,
Vlado

[vlado]

Also, which 3ds Max version?

Best regards,
Vlado

[LudvikKoutny]

Hi,

3ds Max version is Max 2016 SP1 (as written in the thread title)

Once I ran ActiveShade as extended viewport, this is what log printed:

Ok thanks. Does it never update, or it updates only sporadically? I think I've seen that before...

It does not do anything, just completely black screen. I've also got some problems with irregular updates and RT getting stuck, but that was Beta 1, and now it seems resolved in Beta 2, when rendering with floating VFB.

I can also send you a scene if you want, but so far it happens in pretty much any scene i try.

[vlado]

Ok, so this seems to be related to the V-Ray sun. Will fix it.

Best regards,
Vlado

[LudvikKoutny]

Does that apply even if V-Ray Sun is not present in the scene? Because the first scene I noticed it was not working in was scene lit by just one white untextured DomeLight.

[Zdravko.Keremidchiev]

Thanks for the feedback. We will do more research on the issue, it might be that the Dome light causes problems as well.

[LudvikKoutny]

Hi,

is this still being worked on? I am using 3.30.04 and ActiveShade as extended viewport still mostly doesn't work. It is stuck in camera view that's centered in scene origin and looking exactly down on Z axis. It doesn't synchronize perspective or camera view regardless of if "view to render" choice is locked in render settings or not.

[yavor.rubenov]

Hello,

I managed to reproduce similar behavior if the view I change to extended viewport was initially some orthographic view - for example Left/Front or something like this. In that case I get some fixed view that doesn't react to any navigation. This is something we should check..
Is this your case ?


If I first change the view to Perspective or some camera - it starts the way it was but if I move something in another viewport it now reacts as expected.

Best regards,
Yavor

Yep, that's the exact behavior I am experiencing. That's my case. Launching it from perspective/camera view works fine.

[RobH22]

I'm having a similar problem. If I start RT as a CPU render it launches the FBuffer and works fine. If I then try OpenCL it freezes with "Waiting for Data." If I then try Cuda, the FBuffer will come up for about 1/2 second and then disappear. Now none of the 3 protocols will work. I have to restart Max to get back to where CPU will work.

Here is a section from my log. I see some things in the last 20 lines or so that might indicate the problem but I don't know how to interpret them:

Hello,

Seeing from the log You have a Quadro K5200 - I guess you mean you try CUDA not OpenCL ? (For nVidia GPUs you should always use CUDA - it'll be faster).

If CUDA crashes - does it happen on any scene or only on some of them ?

Best regards,
Yavor

[RobH22]

Yavor,

No, I mean OpenCL and Cuda. The workflow I posted is "exactly" what I did to diagnose and generate the log. I was trying all options to get them to work. It happens on ALL files. I made a new one with just a single teapot and it fails. I have the newest NVidia drivers from this month and I reinstalled V-Ray.

What's interesting about the 3 types of RT renders is that they all support different features. CPU supports features that OpenCL and Cuda do not. And, OpenCL supports some that Cuda doesn't so it really boils down to what you need to see. Yes Cuda is faster but if it doesn't render what I need I have to drop back to OpenCL or CPU.

I hope we can figure out what is wrong.
