Upgrade to 3.4 and you wont deal with any of this anymore.

Have you noticed any patterns that lead up to this?

Also:
What SU version?
What OS?

Displacement in your file?

Seriously though, 2.0 is garbage. Upgrade to 3.4 as soon as you can.

You can export the alpha of the render and replace the HDRi with a beach image.

The alpha is the black and white channel which you can use to tweak or replace what's behind transparent surfaces. In Frame Buffer window you have a white circle near RGB values, switch that on and save your file.

Then in Photoshop or Gimp or whatever post production software you use, replace the black with your desired image of a beach.

Hey Angevin,
Something seems wrong, a 1000px render shouldnt be taking hours to finish. I run my test renders that size and they generally take from 30 seconds to 5 minutes to complete...(this is relative to scene and your pc, of course.) Your settings seem cranked up pretty high...in some places...not very balanced either.
I don't think there is any reason to ever have a minimum of 2 subdivs if you're using an adaptive sampler. And 24 subdivs is really high....and .05 is really low (not very balanced). Denoiser can steal a lot of detail, so it isnt a good idea to make it do too much work...specially if you're using irradiance map as you primary bounce. I find Light Cache of 1500 tends to be low for our interior scenes, although .05 sample size is a pretty high one. Usually don't go over -1 for Irr max rate...

Anyway, its a good idea to start with the built in quality presets, (the 'quality' slider under 'Renderer') Medium is a good start, try high if you think it needs it. Then only change one setting at a time and render a small region with the region render window to see if it helps quality without effecting time too adversely. If you're having crashes and long render times, good to try copying and pasting in place the whole scene into a new SU file. Sometimes there is just something corrupted in the file and this is the only/easiest fix. Since Vray 3.4, I'd say this happens to 1 out of every 4 files!!...yeah 3.4 is still pretty buggy...

If you want me to take a look, you can PM me with link to download file and I'll see how it runs on our machines...I'll even hone in some fast quality settings for you. Could give you a good place to start with your settings in the future.

Cheers,
GD

When I render a photo matched texture in V-Ray it distorts. See Below.

Podium renders the same file w/out distortion.

Does anybody know if this issue has been corrected in V-Ray 3?

Since I got that distortion, I started modeling stuff from scratch. Another option could be "Make Unique Texture" directly in SU, which will make the face gain the single texture of window/ cladding/ whatever... but sometimes Make Unique Texture doesn't work good because the object on which you project the texture, goes white.

hi,

same problem... also vray 3.4
did you find any solution yet?

thx!

Still need to figure out how to get alpha to work behind window glass...

Hi Kinga,

I would just make the fog color a very very pale blue. The fog amount depends on the scale of the model, so if you have something that's working for a small test, it will show up much darker on a larger size model. Once you have a light blue color, you may still need to lower the fog multiplier.

Oh, great. I hope 3.5 comes quickly. Nobody has their own wish? Just me?

You render the frames with V-ray and assemble them in photoshop or any post production software which allows merging of consecutive images into a video file.

Hmm... that is strange, if you convert to plain mesh SUbD should not be interfering...

Can you show a video/gif of what you observe? Maybe we are talking about different things?

Hi rjh0016,
I guess you want to check the second icon, bottom left of your render frame called "force color clamping".
(When this icon is unchecked like in your screenshot, this indicates with colors the amount of work for the processor to render the image. The more you go to the red, and then the black, the more difficult the image to calculate. This view is just an indicator for you to know where you could potentially try to simplify the scene to make the rendering time shorter).
Hope this helps.
Have a good day.

Did you assign V-RAM in Windows?

I also had some scenes which froze my laptop with 16GB (14 usable) and after assigning V-RAM scenes worked good. Try this. If not, your trees might be Laubwerk and you lack physical RAM.
