Hi, Seems that for having deep data into our EXR, we need to use Vray VFB. (3dsmax 2014, Vray3.07). We rarely used it because of render elements storing severe limitations, so back there … The problem is : - We need exr with Zdepth deep data inside, and only this. - We need all render elements …

There is no way to do what you want right now. You can render the deep pass separately, but the deep exr will still contain the RGB element. Note that it makes no sense at all to store z-depth element by itself into a deep exr file - the deep points carry the z-depth information anyways (plus mandat…

[image] How do you render against a live action plate in Vray, and have shadows show up? There is no way to do what you want right now. You can render the deep pass separately, but the deep exr will still contain the RGB element. So the “separate render channel” is totally useless. Why would I…

[image] *.exrsl files from VRay Vlado, is there at least a hidden way, via maxscript or python to remove all datas for the exr apart beauty+deep? No. But OpenEXR 2 is open-source, it is relatively straightforward for anyone to write a tool that would extract the channels that you want as separ…

[image] *.exrsl files from VRay And even with a real separates elements option, why can’t I save element x in png 24 and element y in exr rgba ?? <shrug> Because it was not done in the beginning and now it’s a lot of code to change that would break a lot of things. It can be done, but I would …

Vlado, I just spend 10k$ on Vray licences to update to v3. Is it a serious enough reason ? :slight_smile: I will try to write a python script to delete all but deep data in the exr, as post-render script. But not sur there is actually a python module reading deep channel (supporing exr2). I just d…

[image] IES ligths Vlado, I just spend 10k$ on Vray licences to update to v3. Is it a serious enough reason ? :slight_smile: Hehe, when you put it like this, yes. But it won’t happen overnight - like I said it’s a lot of code that needs to be changed, and there will be lots of bugs along the w…

1) If you need special alpha/beta testing for this, we can help you (we are ever for many companies). 2) I can read the file with python 2.7 and openEXR 1.2.0 module. It show all channels (REs are indeed half, generating lot of datas for nothing) and I guess deep data are : - Z FLOAT (1, 1) - ZBa…

3dsmax is awful when it comes to different render formats and render elements, there are some secret stored settings within the render element dialog, it is possible to render MMEs in a different format to the main render but it is a real pain and requires a bit of a hack to do it. I’ve been asking…

[image] 27 inch monitor 3) The whole point of deep file is to get volumetric position of pixels (sort of). So you can add some 2D elements inside 3D elements, deepmerge them, do nice defocus and fog, etc). Yes, and this also has a side effect - the ability to extract any object perfectly, with…

We have thousands of objects in our renders, we don’t do rgb mattes per object, but per materials or per group. Example : thisMetal objects : object ID 1 thisWood objects : object ID 2 thisGlass objects : object ID 3 theseVegetation objects : object ID 4 thisGroup objects : object ID 5 etc … …

Exactly what I meant, yes.

Compositing per object in such renders would take ages …For sure, I wasn’t suggesting that you do that

Best regards,
Vlado
