Vray RT SP1a not working

[Drawehn]

I tried installing Vray SP4a and Vray RT SP1a 64 bit today but couldn't get Vray RT to work.

It seemed to install fine but when going to active shade mode, the file would just freeze up. I tried several files so it's not a file related issue.

Because of that problem, I went back to Vray SP3a and RT 1.5 and that's working fine but eventually I would like to update so any help is appreciated.

Hm, works fine for me here generally. Are there any errors in the render slave window?

Best regards,

No, I don't have any render slaves. I think it might be the same problem like this thread:

Did you ever get that solved, Vlado?

I tried installing SP4a and RT1a again for testing and i found that on some of my scenes it works albeit very slow. When I just create a couple of boxes in an empty scene it works fine. On the scene i am working now for example though it crashes every time i open the active shade window. My scene is not very complex at all though. File size is just 11MB so it's peanuts really and no reason why RT should die on it.

I should be more precise. Max doesn't actually crash, it just freezes up so then I have to crash it..:

The problem in the other thread was a Bitmap texture that does not specify a file name. Could that be the case for you as well? If not, can you get me that scene so that I can check it out?

[Drawehn]

No, all textures are loaded and no empty bitmap slots.
Will send you the file tonight. Thanks Vlado!

[Drawehn]

Vlado, did you have a look at the file I send through and managed to find out why my RT SP1a won't work?

I would like to update to VRay SP4a but there is no point if my RT doesn't work properly.

Thanks.

[vlado]

Yes, I found the problem; I will email you a bit later today.

So the problem seems to be in some Loft objects in the scene; they keep telling the ActiveShade renderer that their geometry has changed, when in fact it has not... I'm still trying to figure out a way around this (other than collapsing them to Editable Meshes).

Ah wow, that's interesting. Thanks for finding out!
