Hi, I am pretty sure that this is doable but I just cant seem to get it to work. I simply am trying to do a shadow matte with the ground plane in RT, cuda rendering. I used the common settings for that (under vray properties), then also tried the shadow catcher button. Alpha for the ground is al…

Everything works fine here: Here is the test scene if you would like to run it into your environment: http://ftp.chaosgroup.com/support/scenes/cuda\_matte.max This is with the latest nightly build from today, revision number 27367. Can you get me the revision number of the build you are using as…

And a video about it. Keep in mind that you have to have texture in the env slot and to restart the RT rendering after the first matte material is added in the scene. Also, please check that you have not disabled the render elements in your scene. Best, Blago.

[image] Request- Film Response Curves (Comparing Octane to V-Ray) Thanks. I will look into it. So that means if only use Vray lights or a dome, the matte will not work? I always need a tex in the env slot? Yeah. But I think it has always been the case for RT (though I might be wrong about tha…

Had to the time to try it out, but the max file you sent me is probably newer than my version (2015) I put a VrayHDRI into the env slot, both in vray settings and the 3dsmax one, but the ground is still visible, not acting as a matte… Edit: I didnt have the VrayMatteShadow in the render elements …

Here is the scene saved to 3dsMax 2015: http://ftp.chaosgroup.com/support/scenes/cuda\_matte\_2015.max Would it be possible to send your scene for investigation? You are probably using something that we are missing and it would take us more time to find it guessing than investigating the scene.

sorry for the late reply. problem still remains. shadow catcher is working in CPU production though. added question: how would I go about using the comp I received from the client as background in RT while using the shadow catcher? matteshadow.zip (31.4 KB)

I set the production render engine as RT too and the shadow catcher worked! didnt know that active shade RT is so dependent on the production render engine. Edit: Next Problem, Vray Adv Production renders the matte plane fine with -1 Alpha, RT gives me a grey alpha with the shadows Adv: RT: [c…

sorry to bring this up again and again, but I retested my scene by importing only the basic geometry in a new resetted scene and then creating new lights. the shadow matte didnt work together with a Vray Dome Light. Just using the vray sun, it worked, but not with the dome light. Deleting the dome l…

Sorry for the delay,
