v-ray lens effects in maya?

[vlado]

The controls are very well hidden within the Color Corrections window. Would it be more user friendly to add the settings as its own icon on the bottom of the VFB?

This is already done, but it's not in the nightly builds yet.

Best regards,

I'm not seeing a render element yet for the lens effects. When I make them, I see a new RE pop up in the VRay Framebuffer, but it contains the entire beauty pass + lens effects on top, so I can't comp it on top in Nuke later on that way. I suppose I could subtract the beauty pass from the lens effects pass to isolate it.

I find it's also a bit hit and miss in terms of when it'll work and when it won't...especially the glare section, bloom seems more reliable.

I think in Max there is a PostFx Element for this. Sounds like a good way to do it.

Hi is there a reason Glare renders out a "soft" version of the entire image rather than just the glare (as in Infinity Visions 3DS Max plugin for V-Ray)?

Using a Catmull Rom AA filter and glare makes everything very soft negating the sharp AA filter. It also would make it better for post just to have a black background of the glare effect.

Well to check, I just downloaded the V-Ray for Max trial and it seems that the "intensity" or glare mask works in 3DS Max, but it seems this is not the case in Maya yet?

This is correct; the masks don't work yet. We'll get to that.

Hi there,

Are the lens effects meant to be working while rendering animation ? I get some nice results for still views, but as soon as I render some animation frames I don't have anymore effect showing up ??!!

Edit: forgot to tell that I'm using build 22281 from nightlies

It's probably a bug; thanks for the pointer; will look at it.

Sorry Vlado. False alert. The lens effect was so hardly noticeable in the first 15frames I tested that I thought it didn't work.
I noticed something else, but will now triple check before making a statement

Hi again,

I think I identified a problem with lens effects.
Sorry for the very small attachment, cannot show more, but I think it shows the problem.
I have some dots/sparkles appearing when using lens effects. I did some more testing and it appears to be in relation with brute force as primary bounces.
I have dots when using BF+BF and BF+LC
I have no dots when using IR+LC and IR + BF

I'm testing right now an animation with IR + BF.

best regards,

olivier

We can't reproduce the issue in here. Would it be possible to attach small example scene?

Hey

The lens effect is just a shader that plugs in to maya camera or an vraycamera?

Hi Zdravko,

If you are referring to the post with the sparkles, I sent already a scene off line (to Svetlozar).

I noticed something else. I'm rendering these days an animation with lens effects (can't show).
First, I found no way to batch render this animation with lens effects but maybe I'm missing something (didn't try creating a vray scene and batch render from vray command prompt yet)
second, when rendering from Maya with DR (using VFB), if I have to restart/complete the rendering ( I already rendered frame 1 -> 200 and want now to render 200 -> 400), at first launch the slaves produce black squares after lens effect post process (not while rendering). I have to stop, launch again, and then it's fine. Is it clear ? :-/

Slaves are loading properly the pre-rendered IRmap (rendering with IRmap + BF).
Still using build 22281 (Maya 2012SP1 + win7pro)

It's controlled via the V-Ray Frame-buffer and can be done as a separate pass.

It's not 100% working yet, but I'm sure it will when its finished
