Vray Render tests for Skin and translucent surfaces

Recommended Posts

  • Topic Author
  • Hello all.

    Iv been busy as of late, one of which is learning Vray4C4D.  while id like to actually work on a complete project im at that phase of learning C4D  and Vray with smaller projects in order to get through the process in as least time as possible.  With that said one of my interest is character portrate and animation and the rendering of realistic skin, seems like its taking forever to get what im after, but slowly but surly its fitting together.

    Here are a few examples of what im getting from Vray comparing 3 materials.  1:Fast SSS2  2:Skin Material  3:Alsurface (new)

    Wow, some very nice renders. Keep up the good work! :Bananeyessss:

    How complex is VRay?

  • Hi.

    Vray, I wouldnt say is over complex but has a hard learning curve more due to the manual which is more of a overview than a learning aid.  For me I had to get right into the beta as that had the features I needed which left me with a outdated manual, you can imaging having to learn from a Max manual and translate that into Vray, and when I hit a problem that was related to vray4c4d I was non the wiser if it was me, the beta or vray in general. Stefan has been quite prompt in offering support over at the "Offical Forum", but I have at times had a hard time understanding his sentence structure, so id need to spend a bit more time to translate it into something of clearer meaning.

    To be honest iv learnt more from playing, mistakes, and reading other peoples issues.  Yea to sum it up id say its complex for a new user who is not technical minded, hard going for someone who needs a clear user guide, and dedicated training, and easy for a technician whos very techie.

    I wouldnt say Vray is for someone who likes to work with presets with hardly any tweaking to do.  The graft isnt necessarily down to understanding the settings in theory, but getting a balance of a multitude of many settings that are sensitive enough to make or break a nice material.

    Nice skin texture! I'd love to see a different body mesh, man, that guy has been hanging around in people's test renders for years now ;)

    I don't use Vray very much but when I was learning it this guy Grant Warwick was the man - he really explains how to optimise the samples and get render times down. You may have already seen his stuff, it's mostly for 3ds max Vray, but it's still really useful.

    Guys, I just got an idea. What do you say, like for example we took some scene and we try to render it with different softwares and then we compare everything we can! Thoughts?

    Yes indeed that's why I chose two of my own models for my own reference, and Miki II from Poser, but the Infinate realities head being used so much is what gives us a comparison.  Digital Emily is the new one used now, but I don't want to spend too much time on someone else's model when I should be getting on with my own.

    Good fun idea, but for a proper comparison iv found an individuals ability, and knowledge of their renderer engine to be a huge factor in the outcome.  Modo has loads of presets for materials, Vray comes with non, just base shaders. My understanding in Vray would make a bad comparison against MODO simply because I don't know it well enough, even although Vray can do better.  The scene would have to be lit by GI, unless the lights can come with the scene in the same place for everyone.  If the scene uses procedurals then that makes it even harder as its going to be bias towards the render engine in which it was set up.

    I think for a fun thing to get the community together it would be a good idea in its own sticky.  As for me, iv got to do some anatomy stuff today for the learning thread I started, the Back is covered in this one.

    Totally agree with this. Hardly anybody (self included) dedicates the proper amount of time to understanding how one renderer works, let alone multiple. Has a lot to do with the skills of the artist as well.

    Only render comparison tests I've found interesting are completely scientific scenes comparing specific renderer features, like how long it takes for good caustics etc.

    We can take simple scenes and use presets, at least with renders who have them. I am aware that complex scenes are no way to go.

  • I can test C4D, MODO, Vray and provide times, and cropped comparisons.  If anything else it will be good to see what differences can be got from the same render engine, different users.

    I use Vray for C4D as well, but I'm busy with other stuff at the moment.

    I like Vray, but I totally agree with Recto that I'm missing a detailed manual. Stefan (provider of Vray for C4D) provides an extensive training (Masterclass 2015), which is good for beginners, but you need to find some settings yourself, when you get into certain details (e.g. skin). Vray has a lot of great shaders, but you even do not get details about the settings from Chaos Group. There are constantly new things coming, but the documentation is behind.

     

    I'm glad that guys like Recto is diving deeper into the skin topic. This certainly will help to get even better skin one day. I also love the new support of AlShader in the new Vray version.

     

    Depending on my workload I will try to contribute as well...

    Thanks, its a subject that has had me interested in for years as a on looker to those who had the higher end tools many years ago.  Its taken me a long time to afford C4D, and Vray, so now its my time to be behind the driver seat and give it a go.  These things take time, and after working in C4D even for a short period of time I know I made the right choice, its artist friendly, and that means a great deal to me, wish Vray was more like C4D, but guess I can have it all ways.

     

    Im also getting some very nice hair rendering that I havent shown yet, so all in all by the time I do my first complete project in C4D I think im going to be happy with the results.

     

    Dan.
