Save seperate render

[Crazy Homeless Guy]

Forgive the ignorance. I haven't used Vray in almost a year now, and I am using it on the project I am putting together now. I was easily able to recall the majority of my previous working methods, but I can't seem to make the Render Elements write out.

 

I am using the Vray frame buffer, and have the "Save separate render channels" ticked under the "Split render channels" roll out. I assume I am missing something blatantly obvious.

 

Thanks in advance.

 

I am still using 1.5sp2, which is where I left off of using it before diving into MR. Hopefully this isn't bug related. I don't want to update until after we get this project out the door.

 

Edit: Also, forgive the post name. I got distracted before I finished typing it, and hit submit before I realized.

travis any particular reason that you've jumped back to vray on this particular job?

It should save out the separate passes if you do a batch render job. Otherwise I believe you need to save them manually.

Partially to compare and contrast the use of MR for our projects, and partially because I still prefer the way Vray pushes light around compared to MR.

 

What I am finding seems to be that Vray is better for quick light, and MR is better for materials, which stays in line with how most people view the two engines. You can do similar stuff with both, but straight out of the box, those seem to be the strengths.

 

Also, Vray's handling of proxies seems to be more effecient than MR, as well as the speed of AA. I think the AA speed has to do with how MR handles its materials, which may also be a reflection of MR having better materials directly out of the box.

 

I am very interested in how Vray handles Arch & Design materials, and that will be something I test after we get this project out. I am curious if using the non native A&D material with Vray slows it down. If it does not, I will be one happy camper. That will allow me to quickly jump back and forth between engines, because each has its advantages depending on what you are trying to do.

Hmmm.... I was sending them via Backburner to the farm, but I was queing each view manually. I didn't use render elements as heavily as I do now when I was using Vray, but when I did I didn't recall it being a problem.

 

I will try a quick Batch job, and see if that takes care of the problem. Thanks.

Batch rendering didn't seem to work for me either. I guess there is a possibility that something is corrupt in my file. I am going to try one from scratch, and see if it still has a problem.

OK, I was not specifying a path in the split render channels. I wrongly assumed it would gather/automatically generate that path from the Render Element / File name in a similar manner to what MR does.

 

So, just to make sure I am correct on this... I need to manually set the Render Channel path for every time I render a different view?

Save separate render channels is not really like Render Elements. It simply will save RGB and Alpha from your images separated, creating 2 different files. For that, you'll have to put a name in the box (like test.jpg, for example). It will then save the 2 files for each rendered frame.

It seems to be saving the Render Elements I have enabled also when I tick the Save separate render channels option. Is there a way to save the render elements without going this route, and without saving them manually?

 

Edit: I added a screen shot of what I am doing. Elements.tif is the name I typed into the split render channel option.

dont suppose switching to max buffer is an option? then it will just work automatically

When I ran my test that worked without a problem. I don't think switching will screw anything up, so that will probably be the best option.

yeh only time i used vray frame buffer was when i was fiddling with LWF.

yup, I agree on this one....

 

Switching to the max buffer is the only way I can get all the render elements to write out into one multichannel EXR. I think you may have to have the connection extenstion installed for that one to work though.....

Second that. Also, VRay's FB is great for large size renderings, allowing one to use the Raw Image File option, which is great. Apart from that, I normally stick with Max's FB. One less thing to worry about.
