Vray Lens Effects

[logan683]

Is anybody else having problems with the Lens Effects setting? Whenever I turn it on in the System settings, render, and finish the render (either cancel or time ends), the lens effects don't show in the VFB and when I close it, Windows gives me a Vray has crashed error. Am I doing something wrong? Thank you.

I have been having crashes as well with lens effects enabled. If I stop the render early, I get a soft crash (a window pops up saying blender not responding. Blender stays open and I can save my work and restart.) No problems if I let the render finish.

Hey, andybot. Thank you for the reply. I get the same soft crash, but whether I let a render finish or not, the lens effects don't take. I'm not sure how else to describe it. I set a render for 30 seconds and it still didn't work. Tried turning off Physical in the camera settings and that didn't work. I've tried all combinations of settings and check boxes in the Lens Effects settings. I've been working on trying to figure it out for two days now and nothing works. I even uninstalled and reinstalled. I'm at a loss.

I just tried the lens effects again with these builds:
vrayblender3-2.76-4c1c02e-x86_64-windows.exe
vraystd_adv_33501_x64_vc11_hwlic_26648

Still getting a crash and no lens effects. Those are the most current builds.

Hey, andybot, is there a way to open the VFB in Blender like there is in Max, or do I just have to render again to open the window? I can't find a way to open it in Blender without having to render. Is there a "Show Last VFB" like in Max that I'm missing? Thank you.

[logan683]

Letting it render to a certain time/threshold doesn't help, either. Still no lens effects and crashing VRay. I've been testing all day with all combinations of settings. The render element for the lens effects in the VFB is a completely black pass.

I don't think it works with the progressive sampler. Try the adaptive DMC.

Seems there is some bug in V-Ray, we're checking this...

@bdancer, thank you for looking at this.

@andybot_cg, thank you for taking your time to look, as well. I really appreciate that.

[logan683]

Just tried with this build:
vraystd_adv_33501_x64_vc11_hwlic_26652

Still a no go.

[logan683]

Still doesn't work with this build, either:
vraystd_adv_33501_x64_vc11_hwlic_26654
vrayblender3-2.76-6de2fea-x86_64-windows

Thank you.

[logan683]

Vray crashes, no lens effects with this build:
vraystd_adv_33501_x64_vc11_hwlic_26655

Thank you.

[logan683]

Still crashing an no lens effects:
vraystd_adv_33501_x64_vc11_hwlic_26658

Thank you.

logan683, thanks for testing, but we'll inform you when the fix will be ready.

Hey, that's really cool. Thank you, bdancer. I appreciate you checking this out.
