Not quite real - Requests?


Recommended Posts

Though the render is amazing, the background looks kinda fake.

For non-fetish what-can-this-engine-do:

Maybe a still image of an action, like a sport. Maybe a snowboarder making a turn, with the snow shooting out like a wave? Something like that. And water, water is always a tricky one when it comes to rendering.

For fetish requests:

Something kinda standard, just a girl wetting or something, though something I kinda dislike is it being extremely over the top, with a way too cartoony expresion etc.

I think I'm going to be the only one not asking for a fetish picture, because I want to give a bigger test of all this rendering stuff by giving them an action sequence to see just how smooth and realistic everything is before going to fetish levels.

This is a better description of what I wanted

I should have been more clear in my original post- At this point I am taking requests for still images only.  Even a single frame takes around an hour to render, assuming it isn't too complex.  At 24 frames per second, it would take a full day just to render a single second of an animation, and that is assuming I don't need my computer for other things.

Which rendering engine are you using? The picture looks really good

My suggestion for a picture to make, or even a sequence:

A girl loosing control waiting in line for the bathroom

I used Nvidia's Iray rendering engine.  

A waiting in line scene should be fairly doable.

That is an interesting observation, as the background was a real photograph and the girl was the only fake thing in the image.

The problem with doing something like a snowboarder making a turn, or fire as someone else suggested, is that while these things are doable, I would have to create shaders for them.  I'm not sure I want to spend an entire day, or longer, coming up with the perfect snow shader and particle system just for a test render.  Water, or other fluids, by themselves are pretty easy, as long as they are static.  It is showing them in motion, where they are transitioning from falling to a container, or in motion, that can be difficult sometimes.

Attached are a couple more sample renders that I spent a bit more time on.

 I only now found this thread. My initial reaction was that the rendering is superb, but the background looks more realistic than the woman. The give away with the woman is her face, especially her eyes. Her hair, arms and clothes all look realistic.

What GPU, CPU (including cores and speed) an operating system are you using?

CPU is an Intel Core i7-6850K at 3.6GHz with a max turbo boost of 4.0GHz under load.  The processor has six cores, but because it is Intel it supports hyper-threading, so it can handle 12 simultaneous processing threads.

For GPUs, which handle most of the rendering work when using Iray (in fact, under render options I can select which processing devices are available for doing a render and disable the CPU entirely), I am using dual Nvidia GTX 1080 cards in an SLI configuration.

I think perhaps the problem with her eyes come from the lighting model that Iray uses.  Instead of using virtual lights and ray tracing, it using HDR photometry, generating a scenes lighting from an HDR sphere.  The idea here is to help seamlessly blend real life and 3D models, movie visual effects often take advantage of this technique.  An artist can capture a photograph of a scene, and an HDR photo sphere of the scene to map the lighting.  Then, digitally insert a 3D object into that scene, match the virtual camera with the real one, and light the virtual object with the HDR sphere to have the lighting match.

Why this caused a problem in my sample scene above is that I wasn't just using a model in a real world scene, but the room itself was part of the 3D scene.  The HDR sphere existed outside that room.  Because rendering speeds are dramatically slowed when caustic calculations are enabled, I didn't use them.  Which meant that light bouncing off the room walls and floors didn't affect the model.  The HDR photo sphere I used was a generic one of an outdoor scene.  So, for the model's eyes, you see the refelection of this photo sphere and lighting that doesn't match the scene she appears to be standing in.

Today I will try to do an omo specific scene, using Iray, and see how it comes out.  However, I doubt that any time in the foreseeable future I will be able to produce a scene that looks 100% real.
