the tests never end.
A client of mine told me: Hey Gabriele, I need a printable 3d virtual scene with high resolution textures, photometric lights, with an inclined camera, with less noise possible and I want to adjust and calibrate materials and objects with you in realtime.
I said: why not?
The client was a beautiful woman...
So I started to use all my rendering tools.
The first software I used was Octane, I modeled all the scene inside 3ds Max, I texturized all the objects, then I exported to Octane and adjusted lights, materials and camera...but I told her: the 1st December I will be capable to move objects too...
BTW I was able to create a good render with tiny lights emitters, acceptable noise, good high resolution textures.
The second software I used was iray. The scene was already modeled so I started to change in realtime lights, materials and cameras using Activeshade.
Every time I changed a texture iray calculated the baking...It was impossible to adjust materials and texture in few minutes, all this work took several hours.
I created a printable render with a lot of noise but photometric lights and good high resolution textures.
The third software I used was Vray-RTgpu. Every adjustment was done in a snap. I was able to move lights, objects, tune materials in realtime but all the textures weren't loaded in the gpu ram because they were converted at 512x512 pixels only. Tiny textures 50x50 pixels were converted at 512x512 pixels, the large textures (6000x6000) too. Was impossible to render a 3500x2500 printable image. BTW the render was cleaner than the other softwares with good ies lights and a lot of detail.
The fourth software I used was Arion. I exported the Max scene using the Arion plugin. Not all the textures and objects were loaded in the gpu ram. I deleted in Max some objects (all the books) and exported again.
Was a snap to change materials but was impossible to roll the camera. When I assigned the light material to the emitters a lot of fireflies appeared over the image. I tried to change every parameter but was impossible to obtain the result that the client of mine desired.
When she asked to me: please Gabriele, move that chair from here to there I told her that was impossible. So I reloaded the original scene in Max moved the chair in the correct position and exported again in Arion. All the materials were reassigned again.
After all these tests, I spent all the rest of the night with my client....
